Visual fault signalling SPD Type 3Combination of varistor surge protection and an encapsulated spark gap. To be installed in low-voltage 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.
The basic principle for surge protection is the complexity and coordination of protections. The complexity requirement can be met only by installing surge protections ...
