Abstract:
A circuit breaker tripping mechanism providing relatively low instantaneous level tripping is disclosed. Circuit breaker tripping mechanism includes an armature with a first portion extending in a first direction from an armature pivot and a second portion extending in a second direction from the armature pivot, and a magnetic field generator configured as part of a line conductor. Magnetic field generator is operable to produce a magnetic field acting upon the second portion during a short circuit. Circuit breakers including the circuit breaker tripping mechanism and methods of tripping a circuit breaker are provided, as are other aspects.
