摘要： Methods, apparatus, and systems are provided for a selectivity device for a circuit breaker. The invention includes a modular assembly adapted to be coupled to a load conductor assembly. The modular assembly includes a tripping plunger including a cam surface adapted to interact with a breaker tripping mechanism; an armature coupled to the tripping plunger; a yoke adapted to generate a magnetic field in response to an electric current in the load conductor assembly and disposed to apply a magnetic force proportionate to the electric current on the armature; and a spring assembly adapted to counter-balance the magnetic force up to a predefined tripping current in the load conductor assembly. Numerous additional aspects are disclosed.

摘要： A slot motor apparatus for a circuit breaker is disclosed. The slot motor has first and second legs connected by a thin web, and an extending portion extending rearward from the rear faces of the legs. Slot motor-arc plate assemblies having an arc plate assembly received at least partially overtop of the extending portion are also disclosed, as are assemblies having the arc plate assembly received very close to the rear faces of the slot motor legs. Circuit breakers, slot motor-arc plate assemblies, slot motor covers, and methods of operating the slot motor-arc plate assemblies are disclosed, as are other aspects.
