Abstract

A trip unit (202) for use with a circuit protection device (104) including a trip mechanism (210) includes a support bracket (302) and a magnet member (304) 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 (402), a second side portion (404), and a rear portion (406) coupled between the first side portion and the second side portion. The trip unit also includes a pivot arm (306) pivotally coupled to the support bracket. The pivot arm includes a first end (602), a second end (604), and a curved portion (606) 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.
