ABSTRACT:
A time delay output apparatus for a circuit breaker includes a switch disposed at one side of a main shaft rotatable in directions to open/close a fixed contactor and a movable contactor, and a delay member disposed between the main shaft and the switch so as to operate the switch with a preset time delay, thereby simplifying the construction and reducing the size as well as enhancing operational reliability by stably obtaining a time delay.
