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 aload conductor assembly. The modular assembly includes a tripping plunger including acam surface adapted to interact with a breaker tripping mechanism; an armature coupledto the tripping plunger; a yoke adapted to generate a magnetic field in response to anelectric current in the load conductor assembly and disposed to apply a magnetic forceproportionate to the electric current on the armature; and a spring assembly adapted tocounter-balance the magnetic force up to a predefined tripping current in the loadconductor assembly. Numerous additional aspects are disclosed.
