ABSTRACT:
A three pole circuit breaker includes, for each pole, an electrical conductor, a magnet in close proximity to the conductor so as to generate a magnetic field when excessive current flows therethrough, an armature adapted to be attracted to the magnet when the magnetic field is generated therein, and an extension spring adapted to restrain the armature from attraction by the magnet. A common translating crossbar is coupled to the extension springs for simultaneously varying forces on the three extension springs, so as to vary a magnetic level for the circuit breakers.
The circuit breaker further includes a housing, a button rotatable within the housing and adapted to be rotated from without the housing, and a cam affixed to the button within the housing. The cam is coupled to the crossbar so that rotation of the button causes translating movement of the crossbar.
Movement of an armature toward its respective magnet causes particular movement of a respective trip bar leg which actuates a circuit breaker mechanism.
