ABSTRACT:
An improved circuit interrupter having a solenoid in series with the line and load terminals with an armature operable to activate a trip mechanism within the circuit breaker upon experiencing current levels indicative of short circuit conditions. The traditional solenoid coil is replaced with a free form conductor stamped in a serpentine pattern with adjacent legs deformed slightly in opposite directions to permit an electromagnetic material to be disposed therebetween. Current is directed through the conductor progressively back and forth through the serpentine pattern and creates a magnetic field in the electromagnetic material which is sufficient to activate an armature when current levels approximate short circuit conditions.
