ZGG40-***(1+1)hs - Type 2 - Sichuan Zhongguang Lightning Protection Technologies Co., Ltd.

ZGG40-75/275/320/385/440(1+1)hs

General

This series is made up of one MOV power modules, one GDT power module and a base.

The ZGG40-75(1+1)hs is used for secondary protection of L(＋)-N(－), N(－)-PE respectively. It is applied to the low-voltage AC power distribution system or DC power supply and connected with equipment in parallel.

The ZGG40-275/320/385/440(1+1)hs are used for secondary protection of L-N, N-PE respectively.

Features

1. Anti-reverse plug.

2. High discharge capacity, low residual voltage.

3. Overtemperature protection.

4. Failure indication and centralized remote signalling alarm dry contacts.

5. Enclosure IP20, UL94 V-0.
