摘要：
A supplemental magnetic trip unit is arranged on the load strap of an industrial-rated circuit breaker to interrupt circuit current upon occurrence of a short circuit fault. The trip unit employs a U-shaped magnet and a hinged armature that articulates the circuit breaker operating mechanism latch to allow the circuit breaker contacts to become separated upon the urgence of the powerful circuit breaker operating mechanism springs.
