ABSTRACT:
A coil and trip mechanism to interrupt an electrical circuit having a dual counter-balanced armature arrangement, one a clapper type armature and the other a plunger type. The clapper armature is mounted for movement between a latched position and a tripped position. The plunger armature is mounted for sliding reciprocal movement in and out of the center of the coil between an extended latched position and a retracted tripped position. The armatures are oppositely spring biased toward each other, the stronger bias being provided by a coil spring urging the plunger armature toward the clapper thus holding it away from the trip coil in the latched position until the trip coil is energized. When the trip coil is energized, its electromagnetic force draws the plunger inwardly compressing the coil spring thus neutralizing its biasing force towards the clapper. The opposite bias urging the clapper toward the trip coil can then become effective and aid the electromagnetic force of the trip coil in moving the clapper from a latched to a tripped position.
