It is a standard equipment (automatic reset type) and 30ms of one-pulse is output at overload tripping. Hold-type circuit is necessary since the output time is short (30ms to 50ms). If continuous output is necessary, use Trip indicator (TI) contact of tripping relay. In addition, Manual Reset type (MRE) can be set for AE-SW as an option. Manual Reset type operates at overcurrent tripping and continuously outputs until manual reset button(front of circuit breaker) is pushed and reset. Moreover, "ON" operation is not available until it is reset.
