JXB1-125 125A MCB

JXB1-125 have delicate appearance, light weight. Excellent and reliable performance, high breaking capacity, rapid tripping and mounted by rail. Its enclosure and components adopts high fire-resistant and shock-resistant plastic of long durability. It mainly serves for protecting the circuits of AC 50Hz/60Hz, 230V of single pole, 400V of two poles or three or four poles from overload or short-circuit, and also for unfrequent making and breaking electrical apparatus and lighting circuit. It conforms with the standards of IEC60947-2.
