Application:

Protects electrical equipments against transient overvoltages caused by direct or indirect lightning strikes or switching processes.

Mainly used on main switchboards, widely used in residential, office or industrial buildings to protect against direct or indirect lightning strikes.

Installation and Maintenance:

Should be installed in parallel in the system.

Power must be cut off before installation, do not operate under charging state.

After installation, open the switch of the automatic circuit breaker (or fuse) and check whether the working condition is normal.

During use, the display window is red, indicating that the lightning protection module is out of order. Please repair or replace it in time.
