Product Description
1.Introduction

DKG-20 3P DC surge protective device is a parallel type module DC power surge protection device(short for SPD), which is dedicated to the lightning protection of photovoltaic DC power distribution system. Adopted high temperature and resistant flame retardant plastic shell, with the features of good sealing, good appearance, easy installation, dust-proof, anti-corrosion and flame retardant, this product can work stably under a harsh environment. This product is used for lightning protection of DC power distribution equipment, such as photovoltaic combiner box, photovoltaic DC power distribution cabinet and grid tie inverter.
It is designed as module with 35mm din rail mounting. It has working indication window in each line. When working indication window turns red, the SPD breaks down. With temperature control circuit breaker and built-in over current protective circuit, this modular SPD can automatically release to avoid fire danger when it breaks down. The optional remote alarm function is convenient for remote monitoring and automated management. The main module and the base are replaceable. It can be used for lightning protection of  +--PE,---PE.
