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.
Claims17
A time delay output apparatus for a circuit breaker, comprising:
- a switch disposed at one side of a main shaft rotatable in respective directions to open/close a fixed contactor and a movable contactor;
- a delay member disposed between the main shaft and the switch so as to operate the switch with a preset time delay;
- and
- a reset plate disposed to be separated from the delay member and to interact with the main shaft so as to generate the time delay, thereby transferring a driving force of the main shaft to the delay member.
