GENERAL
WM11-125 Series Minature Circuit Breaker is such features as delicate appearance, light weight, excellent and reliable performance, high breaking capacity, rapid tripping and mounted by rail. Its enclosure and com-ponents adopts high fire-retarding and shock-resistance plastic of long durability. It mainly serves for protecting the circuits ofAC 50Hz,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 ofIEC60947-2.
