Circuit protection device and trip unit for use with a circuit protection device

A circuit protection device comprising:

• an input terminal configured to receive a current;
• an output terminal configured to be electrically connected to said input terminal and to transmit the current to at least one load when said output terminal is electrically connected to said input terminal;
• a trip mechanism configured to electrically disconnect said input terminal from said output terminal;
• a trip bar coupled to said trip mechanism and configured to operate said trip mechanism;
• and
• a trip unit positioned about said trip bar and comprising:
• a support bracket comprising:
• a mounting portion;
• a retention portion coupled substantially perpendicularly to said mounting portion;
• and
• a pivot area positioned at an intersection of said mounting portion and said retention portion;
• a magnet member coupled to said support bracket and configured to:
• receive the current from said input terminal;
• and
• emit a magnetic field based on the current received;
• and
• a pivot arm pivotally coupled to said support bracket, said pivot arm comprising:
• a first end;
• a second end positioned substantially perpendicular to said first end;
• a curved portion coupled to said first end and said second end, wherein said pivot arm is configured to pivot towards said magnet member to cause said trip bar to operate said trip mechanism to interrupt the current when the current exceeds a first threshold;
• and
• a pivot edge configured to be positioned in contact with said pivot area to enable said pivot arm to pivot through at least a portion of said pivot area.
