brennenstuhl® has decades of experience in the field of extension leads and power distribution. The first brennenstuhl® extension lead was created in 1984 - Since then, brennenstuhl® extension leads have been convincing above all with their quality and safety.
brennenstuhl® extension leads are available with an illuminated on/off switch, increased contact protection, with USB, surge protection, for wall mount or many other features. Already in the developing process, brennenstuhl® sets priority on the quality and safety of the products.
There are significant differences in extension leads - depending on the application, power strips require extra features such as multiple sockets with USB, with surge protection, with main-follow function or they are wall mountable.
A multiple power strip is needed when you do not have enough wall sockets available or within reach. An extension lead, also known as a extension cord or power strip, provides several electrical devices with standardised plug connections with a connection to the mains. This makes it possible to flexibly supply several electrical devices with power at the same time.
brennenstuhl® offers extension leads for almost every application. From the common 3-way power strip to the sophisticated high-tech extension lead with surge protection, automatic function and other intelligent features, brennenstuhl® extension leads meet the most diverse requirements. brennenstuhl® power strips are available with illuminated on/off switch, increased touch protection, with USB charger, surge protection, main-follow function and many other features.
There are different types of multiple socket outlets and brennenstuhl® offers a large selection of functionality. We will show you how to find the perfectly suitable extension lead for your needs.
Extension leads with illuminated on/off switches are available in various designs. The classic version is the extension lead with one illuminated on/off switch that supplies power to all sockets simultaneously or disconnects them from the mains. A 2-pole switch disconnects or closes the live wires.
In addition, there are extension leads with hand/foot switches. Multiple plugs with an external switch are ideal if the power strips are in hard-to-reach places, for example under the sofa or behind the cupboard. However, the switch with extra cable means that the socket outlets can still be conveniently switched.
There are also extension leads with several switches to individually supply power to sockets.
Individually switchable extension leads enable electrical appliances to be switched on and off individually without interrupting the complete power supply of the other electrical appliances plugged in.
With radio-controlled socket strips, the plugged-in devices can be conveniently controlled by remote control or app. Thanks to intelligent radio control, you can connect all the devices you want up to 3,500 W to the radio-controlled power strip and operate them from the comfort of your couch. Of course, the power strips can also be switched manually and independently of the remote control or app.
Power strips with a USB charger enable to charge electronic devices such as smartphones or cameras via the USB sockets. The USB charging function for brennenstuhl® extension leads is available with a maximum total charging current of 2.1 A or 3.1 A.
Charging devices even faster is possible with the technology for fast charging: Power Delivery. With Power Delivery technology, connected devices such as laptops, smartphones or tablets are charged up to 70% faster. Thereby, the USB charging cable connection type C is used.
The brennenstuhl®estilo USB charging stations with multiple sockets are extremely practical for convenient charging of notebook, smartphone or tablet, for example on the sofa or bed. Due to their compact form, the multiple extension leads are also ideal for on the go or as a multiple charger when travelling.
Surge protection pays off. Lightning strikes can cause overvoltages in power, telephone or antenna lines. Extension leads with surge protection can reduce voltage peaks so that the connected devices are not damaged. Avoid damage to your electrical appliances by using surge protection products!
The wall-mountable power strips make it easy to keep things tidy and also eliminate annoying cable chaos and possible tripping hazards. Various brennenstuhl® extension leads are equipped with screw holes for optimum fastening of multiple sockets. Alternatively, the extension leads can also be fastened very well with cable ties.
brennenstuhl® has high-quality extension leads with 19" or 10" format. These extension leads for control cabinet technology in industrial quality are suitable for installation in network or server cabinets where the inch format is used.
The multiple socket outlets in inch format have been specially designed for IT racks and protect the valuable technology of server cabinets, for example with overvoltage protection and mains filters.
Even more space and order on the desk is created by extension leads for the desk, which are available for mounting or installation.
A practical feature of retractable socket outlets for installation in tabletops or work surfaces is that the extension lead can be retracted and extended as required.
This type of brennenstuhl® extension lead in a practical, square shape allows access to the power source from all sides. Placed centrally on the table, this is a practical feature especially when a partner, family member or colleague is still at the table together.
The brennenstuhl® socket tower with USB has a non-slip design on the underside. This means that the socket tower stands stably on the table. The brennenstuhl® Alea socket cube is available with or without USB, it can be firmly installed with the table by screwing on the holder provided.
The brennenstuhl®estilo corner extension lead can be used in many ways, for example as a kitchen socket strip. Thanks to its special shape, it can be mounted horizontally in corners or vertically on the worktop on the wall.
The multiple socket for the kitchen, office or other places of use can be easily attached to work surfaces and walls with special adhesive pads. This means that no drilling is necessary for attachment.
Master-slave extension leads are also available from brennenstuhl® - brennenstuhl® designates the technology Main-Follow.
These power strips have a practical automatic switching system that helps save electricity and provides more convenience.
If the device connected in the Main-socket is switched on, all units in the Follow-sockets are automatically activated. When no more current flows through the Main-socket, the Follow-sockets are automatically switched off.
Outdoor extension leads have at least IP44 protection. An outdoor extension lead should have dust and splash-proof sockets with sealing ring and self-closing hinged covers to protect against dirt or water.
The smart home brennenstuhl®Connect offers several smart sockets. The smart extension lead can be installed via WiFi through the router and then operated via app or voice assistant.
The 3-way brennenstuhl®Connect Ecolor WiFi extension lead has also been awarded the iF DESIGN AWARD 2020.
Power strips with a USB charger offer the possibility of charging end devices such as smartphones, tablets, cameras and many more directly at the power strip with USB charger.
The USB charging function with a type A connection for power strips is available with a maximum total charging current of 2.1 A or 3.1 A.
Charging devices even faster is possible with the technology for fast charging: Power Delivery. With Power Delivery, various battery-powered devices can be safely charged within a short time via a USB C connection, regardless of the manufacturer. With the Power Delivery technology for fast charging of batteries, connected end devices such as laptops, smartphones or tablets are charged up to 70% faster.
Whether you want to charge your smartphone, tablet, smartwatch or laptop, if the device has Power Delivery technology, it can be charged via USB C with Power Delivery quick charging. More information on USB C fast charging with Power Delivery is available in the brennenstuhl® selection of themes.
Extension leads can provide protection against various types of leakage currents. These can occur due to lightning strikes or overvoltages. The protection is limited to a certain amperage in each case. The higher the selected amperage, the higher the maximum surge protection offered by the extension lead.
Surges are all overvoltages that exceed the limit value of the mains voltage for a short time. Without effective surge protection, the overvoltages destroy sensitive electronic components in the circuits of the connected devices.
Protection against overvoltages and electromagnetic current peaks can be achieved by using surge protection extension leads, which are used between the power supply (socket) and the device. These ensure that dangerous overvoltages are diverted within fractions of a second and thus protect the devices plugged in.
There are various reasons why a surge protection product is worthwhile. The financial damage and annoyance is great afterwards when expensive electrical appliances such as televisions, computers or kitchen machines are damaged by lightning strikes and surges. To avoid these surges, a surge protector can reduce voltage peaks to a level that is not dangerous for the end device.
The maximum surge current for surge protection extension leads indicates how much current can be discharged without destroying the protective device. The higher the value, the more smaller overvoltage peaks the extension leads with surge protection can absorb without damaging connected devices.
The most dangerous causes are very high voltage peaks triggered by indirect lightning. Power surges also enter the power grid through indirect lightning in enormous current strengths or reach computer systems, video and hi-fi equipment via the telephone and antenna lines and destroy these devices without appropriate protection. If you want to protect your electrical devices from damage or destruction by high voltage peaks, it is better to connect them to an extension lead with surge protection.
Further questions about surge protection extension leads are also answered in the brennenstuhl® world of themes.
In order to find the right extension lead, you can ask yourself a few questions before purchasing:
Which plugs for extension leads? Is a space-saving flat plug needed if the multiple socket is plugged in behind furniture, for example, or does a practical angled plug fit the requirements better.
What types of socket? Multiple socket strips can contain sockets for different types of plugs, for example USB chargers, Euro plugs or earthed plugs. It is important to pay attention to the increased protection against accidental contact for socket outlets.
How many sockets for multiple socket outlets? Common multiple socket outlets are 3-way, 8-way or 10-way power strips. brennenstuhl® extension leads are available with 2 or more sockets and up to 16 sockets.
How should extension leads be arranged? The socket arrangement can also be important. If you choose a 90° arrangement, for example, you can easily plug in large plugs or angled plugs without blocking other socket positions. There are also extra brennenstuhl® extension leads with an extra large distance between sockets.
How long must the extension lead cable be? To ensure that the extension lead is long enough for every application, there are power strips with different cable lengths from 1.5m or 3m up to 5m.
Cable quality for power strips? With brennenstuhl® extension leads we use a high-quality cable.
What additional functions does my extension lead need? Are switches needed? Do appearance and design play an important role? Is a higher IP protection class required for outdoor use? Is surge protection worthwhile?
Do socket outlets need increased protection against accidental contact? Of course, safety comes first and foremost, which is why increased contact protection for socket outlets is always worthwhile.
Industrial extension leads with personal protection? An PRCD serves as mobile protection against electrical accidents between the socket and the appliance. It disconnects the active conductors from the mains at lightning speed as soon as residual currents occur.
IP protection class for extension leads? The IP44 protection rating indicates that the device is protected against foreign bodies and splashing water and that the extension lead is therefore suitable for outdoor use.
IP = International Protection
4 = (first digit) Protection against solid foreign bodies
4 = (second digit Protection against water
Increased contact protection on extension leads serves as a protective mechanism on socket outlets. The contact protection used in brennenstuhl® extension leads is based on the use of plastic sliders which close the openings to the contacts of the socket.
It is easy to carelessly connect different devices to a power strip without paying attention to the maximum load capacity. If you carelessly connect several devices to one extension lead without paying attention to the total power, you will quickly overload the extension lead.
That depends on the power limit of the extension lead, which is indicated on the rating plate, for example. Usually, the maximum load capacity for extension leads is about 3,500 watts. However, what sounds like a lot is quickly consumed. Three devices are enough to fully utilise the power of the extension lead.
When an extension lead is overloaded, it can heat up enormously. This can cause a "smouldering fire". A smouldering fire means that there are no visible flames at first. This makes it all the more dangerous because it is not easy to detect. Dust or other flammable materials can then cause a flame fire to start and spread until the surrounding area catches fire.
In general, you must not plug in several extension leads one after the other. This is even indicated on the extension lead with a warning "do not plug in one after the other". The reason for this is the increased risk of overloading the extension lead.
The ZEIT publishing group declares brennenstuhl® "Brand of the Century". The "German Standards - Brands of the Century" are among the oldest awards in Germany. brennenstuhl® was honoured for its unique position in the category "The extension lead".
