Modular Power Supply Surge Protective Device(Class I Test)

Product Introduction

DK-50G Modular Power Supply series SPD is designed according to IEC standards. It complys with the requirements of GB18802.1-2011 Low-voltage Surge Protective Devices——Part 1: Surge Protective Devices connected to low-voltage power distribution systems——Requirements and tests. It is designed as module, with features of good seal ability and 35mm din rail mounted. With temperature control circuit breaker and built-in over currents protective circuit, the modular SPD will automatically release to avoid fire danger when it it breaks down. It consists of remote alarm connector for remote monitoring. It can be used for protection lightning of L-PE and N-PE.
