Abstract
A trip actuator (,) includes a trip spring (,) to bias the trip arm (,) in a clockwise direction about trip arm pivot (,). In the latched and ready to operate state, the clockwise moment about the axis of the latch pivot (,) created by force “F” opposes the counterclockwise moment created about the axis of the latch pivot (,) created by the horizontal component “f,” of force “f”, to hold the latch (,) in the upright position against the force of the trip arm (,). When a trip (triggering) signal is provided to the flux shifter (,), the flux shifter (,) releases the plunger (,). With the force “F” removed, the trip arm (,) will drive the latch pin (,), causing the latch (,) to rotate counterclockwise about the latch pivot (,). As the latch (,) and trip arm (,) rotate, the latch pin (,) slides off the latch surface (,), fully releasing the trip arm (,) and allowing the trip paddle (,) to move the secondary latch tab (,).
