ZGG40-760(3+0)e
General
The ZGG40-760(3+0)e Modular Power Supply SPD consists of three MOV power supply modules and a base. It provides secondary protection for L-PEN, and is equipped with anti-plug protection. This Modular Power Supply SPD features over-temperature protection, failure indication, and centralized remote signaling dry contacts. The dry contacts facilitates remote monitoring of the modular installation status and operating status.

Features
1. Reverse insertion protection
2. High discharge capacity and low residual voltage
3. Overheating protection
4. Failure indication and centralized remote signaling alarm dry contacts
5. Degree of protection: IP20; housing flammability: UL 94 V-0
