Abstract
Certain exemplary embodiments comprise a bimetal restraint adapted to restrain a bimetal of a circuit breaker from deformation beyond a predetermined threshold during a short circuit event. In certain exemplary embodiments, the bimetal restraint can be adapted to act as a shunt during the short circuit event to transfer electrical energy from an electrical energy source to a load side of the circuit breaker.
Claims19
A system comprising:
- a bimetal restraint adapted to restrain a bimetal of a circuit breaker from deformation beyond a predetermined threshold during a short circuit event, said bimetal restraint adapted to act as a shunt during said short circuit event to transfer electrical energy from an electrical energy source to a load side lug of said circuit breaker, said bimetal restraint not attached to a cover of said circuit breaker and said bimetal restraint releasably seated in a circuit breaker case of said circuit breaker.
A device comprising:
- a bimetal restraint adapted to restrain a bimetal of a circuit breaker from deformation beyond a predetermined threshold during a short circuit event, said bimetal restraint adapted to act as a shunt during said short circuit event to transfer electrical energy from an electrical energy source to a load side lug of said circuit breaker, said bimetal restraint nondestructively detachable from a case of said circuit breaker in an operative embodiment, said bimetal restraint adapted for fastenerless installation in said case of said circuit breaker.
A method comprising a plurality of activities, comprising:
- installing a bimetal restraint adapted to restrain a bimetal of a circuit breaker from deformation beyond a predetermined threshold during a short circuit event, said bimetal restraint adapted to act as a shunt during said short circuit event to transfer electrical energy from an electrical energy source to a load side lug of said circuit breaker, said bimetal restraint not attached to a cover of said circuit breaker.
