Leakage currents

Products compared with practical examples What does the leakage current mean in the case of socket strips with overvoltage protection?

The max. leakage current in the case of socket strips with overvoltage protection indicates how much electricity can be discharged without the protective device being destroyed.

The higher the figure, the greater an overvoltage in the power supply can be without the protective devices being destroyed and the higher the leakage current, the more smaller overvoltage peaks the socket strips with overvoltage protection can sustain without being damaged.

The components and protective elements, such as voltage-dependent resistors and gas discharge valves, in the socket strip are a measure ensuring that dangerous overvoltages are earthed in split seconds, thus not allowing the destructive, high voltage to reach the protected electric appliances.

Structure of overvoltage protection in the case of multiple socket strips

Overvoltage protection modules consist of various electrical components, the correct selection and arrangement of which provide for a high-quality protective function:

  • Voltage-dependent resistors
  • Gas discharge valves (encapsulated spark gaps)
  • Thermal fuse
  • Overvoltage protection display

Heroic lightning and overvoltage protection

A superhero in the stormy sky: the “Bretector” can be found on all packaging of the socket strips with overvoltage protection products and is to facilitate the distinction between traditional socket strips and lightning and overvoltage protection socket strips. 

In addition, the classification according to the star system is to offer fast orientation on the packaging:  a table on each pack shows which overvoltage protection socket strips we would recommend for professional, sophisticated and standard electric appliances.

 

For high-end product and products that represent a monetary or non-material value for you, we recommend overvoltage protection socket strips with a max. leakage current of 30,000 A to 120,000 A. High-end devices are especially expensive and are always more efficient; however, they thus also react more sensitively to overvoltages.

For sophisticated electric appliances such as games consoles or charging stations, we recommend overvoltage protection socket strips with a max. leakage current of 19,500 A.

For standard electric appliances such as coffee machines, kettles and mixers, we recommend overvoltage protection socket strips with a max. leakage current of 13,500 A.

In the case of electric appliances that are particularly important to you, we recommend supplying them with a higher leakage current.
