Abstract
An auxiliary switch activation mechanism is provided for use with a circuit breaker having an auxiliary switch and an operating mechanism for opening and closing main electrical contacts. The auxiliary switch activation mechanism includes a lever having a first end removably connectable to the operating mechanism, a second end of said lever removably connectable to the auxiliary switch, and a spring, mechanically coupled to the lever, which imparts a rotational bias on the lever. The lever provides an assisting force to the operating mechanism for opening the main electrical contacts.
Claims17
An auxiliary switch activation mechanism for use with a circuit breaker having an auxiliary switch and an operating mechanism, said operating mechanism for opening and closing main electrical contacts, said auxiliary switch activation mechanism comprising:
- a lever having a first end removably connectable to said operating mechanism;
- a second end of said lever removably connectable to said auxiliary switch;
- and
- a spring, mechanically coupled to said lever, said spring imparting a rotational bias on said lever, wherein said lever provides an assisting force to said operating mechanism for opening said main electrical contacts.
A circuit breaker, comprising:
- a first electrical contact;
- a second electrical contact arranged proximate to said first electrical contact;
- an operating mechanism configured to separate said first and second electrical contacts, said operating mechanism including a rotary contact assembly operatively connected to said first electrical contact;
- and
- an auxiliary switch activation mechanism, said auxiliary switch activation mechanism further comprising:
- a lever having a first end removably connectable to a crank in said rotary contact assembly;
- a second end of said lever removably connectable to an auxiliary switch;
- and
- an activation spring, mechanically coupled to said lever, said activation spring imparting a rotational bias on said lever.
