HANNOVER MESSE 2020,
20 - 24 April
Replaceable module, visual fault signalling
Combination of varistor surge protection and an encapsulated spark gap connected in the mode 1+1. To be installed in lowvoltage distributions at the boundary of LPZ 2 and LPZ 3 zones to protect distributions and equipment against overvoltage effects induced during a lightning strike and to prevent switching overvoltage. Optional remote status signalling (S).
The basic principle for surge protection is the complexity and coordination of protections. The complexity requirement can be met only by installing surge protections ...
