Protection device surge type 2
Scope
- types of networks (TN, IT, TT)
- connection method
- rated voltage

apparatus consisting of a varistor and a surge arrester encapsulated spark gap combined into module 1 + 1. To install a low-voltage switchgear in the border zones ZMZ 1 - 2. ZMZ serves to protect the wiring and equipment against surge caused by lightning and switching surges
Remote signaling optionally provided (S)
