Application:

For AC power system protection.

It provides protection for equipment of low-voltage AC power system from transient overvoltage damage caused by lightning strikes.

It is suitable for the second level lightning protection of three-phase system

Installation and Maintenance:

After installation, check whether the protection unit is inserted in place, close the circuit breaker (fuse) switch, and check whether the working state is normal.

When the fault indication window changes from green to red, please replace it as soon as possible.
