Product Introduction
module PV Series DC surge protection device (short for SPD) can be installed in front of the low-voltage distribution system. It can prevent the system and equipments from the permanent damage caused by induced over-voltage, over current, and other induced surge voltage. It meets the IEC and GB18802.1 standards. The quality control is under strict ISO9001 Quality Assurance system.
This product uses high temperature and resistant flame retardant plastic shell. It takes the features of good sealing, good appearance, easy installation, dustproof anticorrosion flame retardant, long service life under a harsh environment etc.
 It is designed as module with 35mm electrical lead rail. Each line of SPD module has working indicator window. When the indicator window shows green, the SPD is normal, shows red, the SPD is failure.
With temperature control breaker, build-in over current fuse protector, thermal inductance breaker and degradation automatic release, it can avoid the fire danger. With remote alarm connector, it can facilitate remote monitoring and realize automation management. Its protection mode is L-PE.
