Features:
1 Single phase or three phase, fits all kinds of power systems.
2 Modular separation structure, easy to install and maintain.
3 Visual indicate window
4 Remote signalling contacted, and remote control
5 Through-flow capacity, low residual depression, fast response time
6 double heat tripping device and temperature control breaking technology
Classified as voltage limiting type SPD, apply to the first protection for the low voltage equipments linked with power line road, to the interference caused by overvoltage, it is installed on LPZ0A -1 or higher interface.
Especially fits for the power box.
