GDM20 Y, J series molded case circuit breakers are used for AC 50Hz rated working voltage 380V and below, and its rated electric current ranges from 16A to 630A. They are generally used in a power distribution, to distribute electrical energy in a distribution network. Among them, Y and J type rated currents of 225A and below and 400Y type circuit breakers can also be used as protection motors. The transparent molded case circuit breaker has a visual switch state with visible breakpoints and can also be used as an isolating switch. The circuit breaker can also be equipped with auxiliary accessories such as auxiliary contacts and shunt release.
