ABSTRACT:
A multipole circuit breaker having a housing with a top wall center recess receiving a center strut of an interior trim. An operating assembly is interconnected with a trip assembly through a transistor link passing beneath the center recess and is operable by the magnetic assembly to assist the operating assembly in separating the breaker contacts in response to a fault current. A closure member overlapped by the interior trim prevents access to the load wires. A voltage reject configuration is provided on the housing to prevent mounting in a panelboard designed to carry voltages higher than that for which the circuit breaker is rated and a jaw assembly for the breaker is disclosed having a plurality of contact positions with each leg of a U shaped bus stab.
