摘要： A delay time generation apparatus for an air circuit breaker according to the present invention can provide an effect of ensuring a delay time as long as possible even in a narrow space upon outputting a signal related to a conductive state, by virtue of interaction of a main shaft, a pin portion, a first rotating unit, a second rotating unit and a spring member.

摘要： The present disclosure relates to a magnetic trip device for a circuit breaker capable of maintaining fault information indication until a user removes the cause of an accident subsequent to a trip operation and resets the magnetic trip device. The device comprises an actuator coil part having a plunger; an output plate; a micro switch outputting an electrical signal indicating a state of the circuit breaker; a switch driving lever mechanism rotating to press and releasing the micro switch; a driving lever bias spring elastically biasing the switch driving lever mechanism to rotate; an automatic reset mechanism pressing the plunger to a retracted position; and a driving lever latch rotating to a restraining position for preventing the switch driving lever mechanism from rotating to a first position, and a release position allowing the switch driving lever mechanism-to rotate to the first position.

摘要： A magnetic trip device comprises an actuator coil part having a plunger; an output plate configured to rotate in a first direction by the pressing of the plunger; a micro switch configured to output an electrical signal indicating a state of the circuit breaker; a switch driving lever mechanism configured to rotate to a first position for pressing the operation lever portion and a second position for releasing the operation lever portion; a driving lever bias spring for elastically pressing the switch driving lever mechanism; an automatic reset mechanism for pressing the plunger to the retracted position; a driving lever latch configured to rotate to a restraining position for preventing the switch driving lever mechanism from rotating to the first position, and a release position; and an avoiding portion formed on the output plate to avoid contacting with the switch driving lever mechanism.
