Abstract
A magnet assembly for actuating a trip latch in a circuit breaker. The magnet assembly includes a core and an armature. The core is disposed around a conductor forming a primary current path in the circuit breaker, and includes an end forming a pole face. The armature is biased by a force acting in a direction away from the pole face. The armature includes a generally planar surface and a projection extending from the generally planar surface toward the pole face. The generally planar surface is separated from the pole face by a first air gap, and the projection is separated from the pole face by a second air gap. The first air gap is larger than the second air gap.
