Abstract
In an instantaneous-tripping circuit breaker, a heater-mounted main bimetal, a shifter of a differential shifter mechanism, and an adjustment dial of a thermal overload/open-phase tripping device are removed from a standard circuit breaker equipped with a breaking section, an opening and closing mechanism section, a thermal overload/open-phase tripping device, and an electromagnetic instantaneous tripping device in a case. Instead, a trip coil of the instantaneous tripping device is connected to a main circuit via a connection conductor of a low resistance, a test-tripping part is mounted in place of the shifter of the differential shifter mechanism, and the adjustment dial is replaced with a dummy dial. Accordingly, the standard circuit breaker is changed to an instantaneous-breaking circuit breaker.
