Abstract
PURPOSE: To simplify check work of trip device, by forming the device such that testing device and static type trip device are connected with a connector.
CONSTITUTION: In the device, main circuit 1 of air circuit breaker, converting circuit 2 in which alternating current signals of transformers 1-2 are converted to direct current voltage signals, trip circuit 3 which has long time, short time and instantaneous trip characteristics, and testing device 5 of static trip device which is connected to these circuits 2,3 through connecting terminal 6. Thus, the device can be simply checked by connecting the testing device 5 and the static type trip device with the connector 6. Therefore, the static type trip device can be checked without drawing out the air circuit breaker from a panel in which air circuit breaker is contained.
