Product Description

Product Description

ALP intelligent low voltage line protector

 

ALP200, ALP220 and ALP320 series intelligent low line protectors (hereinafter referred to as ALP) apply to low-voltage system with rated voltage to AC 600V, rated current to AC 400A and rated frequency of 50/60Hz. The product is small in volume, compact in structure and convenient in installation, which is intelligent integrated unit for protecting, monitoring and controlling low voltage feeder terminal.

ALP series products have integrated protection, measurement, control and bus communication into one and provided remote auto control, site direct control, panel indication, signal alarm, operation record, trip alarm record and switch quantity record and other functions, applying to coal mine, petrifaction, smelting, electricity, ship and civil architecture and other fields.
