A trip unit for use with a circuit protection device including a trip mechanism includes a support bracket and a magnet member coupled to the support bracket. The magnet member is configured to emit a magnetic field when a current is transmitted through the trip mechanism. The magnet member includes a first side portion, a second side portion, and a rear portion coupled between the first side portion and the second side portion. The trip unit also includes a pivot arm pivotally coupled to the support bracket. The pivot arm includes a first end, a second end, and a curved portion coupled to the first end and the second end. The pivot arm is configured to pivot towards the magnet member to cause the trip mechanism to interrupt the current when the current exceeds a first threshold.

A rotor assembly may include first rotor half, a first spring supported with the first rotor half, a second rotor half, and a second spring supported within the second rotor half, wherein the first rotor half and the second rotor half are adjoined to enclose the first and second springs. A coiled section of each spring may surround a rotor center pin. A contact arm positioned between the springs may include a non-circular opening. A method for assembling such a rotor assembly is further described.
