Application:

It is suitable for the environment of bad lightning protection, but the equipment pressure resistance is low. It can play an excellent protective effect on electrical equipment.

Suitable for lightning protection of I+II class (B+C class) power supply system

Suitable for 230/400V (50/60Hz) transient overvoltage protection

Installation and Maintenance:

Wire according to the wiring diagram and the surge protector mark
Installation and maintenance should be carried out by professionals
When the indicator window is "red", the surge protector should be replaced immediately.
