Claims17
An accessory for use with a circuit breaker, the circuit breaker including a separable contact structure, an operating mechanism for opening and closing the separable contact structure, the accessory comprising:
- an electrical device having a movable component;
- a first member, the first member interacting with the movable component for movement between a first position and a second position;
- and
- a second member, the second member including a first portion and a second portion, the first portion being configured to be engaged by a pin portion of the first member when the first member is in its first position and to be released by the pin portion of the first member when the first member is moved to its second position, and the second portion being configured to interface a portion of the operating mechanism, the release of the first portion of the second member by the pin portion of the first member causing the second portion of the second member to interface the portion of the operating mechanism.
An accessory for use with a circuit breaker, the circuit breaker including a separable contact structure, an operating mechanism for opening and closing the separable contact structure, the accessory comprising:
- an actuator having a movable plunger;
- a plunger link, the plunger link having a portion being configured to be struck by the plunger for movement between a first position and a second position, and a pin portion;
- and
- a trip member, the trip member being configured to be engaged by the pin portion when the plunger link is in its first position and to be released by the pin portion when the plunger link is moved to its second position, the release by the pin portion causing the trip member to be displaced, the displacement of the trip member interfacing the operating mechanism to open the separable contact structure,
- the trip member being configured by including a seat portion that interfaces the pin portion, the seat portion being configured to set a gap between the plunger link and the plunger.
