Abstract: A circuit breaker thermal-magnetic trip unit for arcing fault detection includes a current transformer having a gapped magnetic core arranged around the load side of the trip unit. The bimetal within the trip unit is positioned abutment with the gap in the transformer core to thereby heat the bimetal causing the bimetal to trip and separate the circuit breaker contacts.

Abstract: A multi-pole circuit interrupter configured to be coupled between an AC source and an electric load electronically detects a hazardous condition associated with energizing of poles and responds to overcome the hazardous condition using a solenoid. The multi-pole circuit interrupter comprises a first switch to energize a first pole on a phase A conductor of the multi-pole circuit interrupter and a second switch to energize a second pole on a phase B conductor of the multi-pole circuit interrupter. The multi-pole circuit interrupter further comprises an electronic solid-state circuit coupled to the phase A conductor and the phase B conductor to detect a line voltage variation and control a current to a device in response to trip an energized pole among the first pole and the second pole if only one of the first pole and the second pole is energized when a user controls a tie bar to turn ON or turn OFF the multi-pole circuit interrupter or when a trip bar fails to trip one of the first pole and the second pole.

Abstract: An apparatus and a method are provided to block and unblock a breaker handle of a circuit breaker having main contacts. The apparatus comprises a locking mechanism including a locking handle shaft and a locking latch. The locking handle shaft is configured to latch the locking mechanism for keeping the breaker handle in a mid-position in which the main contacts stay open. The locking handle shaft has a latching surface configured to be removed from its position in order to rotate the breaker handle to a fully ON position in which the main contacts fully close. The locking latch is configured to prevent rotation of the locking handle shaft. The locking latch is configured to engage and disengage with the locking handle shaft in order to rotate the breaker handle from a reset position to the mid-position in which the locking mechanism locks the breaker handle rotation thus preventing the main contacts from closing. The breaker handle is stopped at the mid-position by the locking mechanism until a self-test is passed.

Abstract: An electrical switching apparatus includes a transductor circuit that senses a direct current between an input terminal and an output terminal and outputs an alternating current proportional to the direct current. The electrical switching apparatus also includes a current sensor configured to sense an alternating current component of the direct current. The electrical switching apparatus further includes an alternating current electronic trip circuit including an arc fault detection circuit configured to detect an arc fault based on the sensed alternating current component. The alternating current electronic trip circuit is also configured to control pairs of separable contacts to trip open based on the alternating current output from the transductor circuit or the detected arc fault. The electrical switching apparatus also includes a power supply structured to provide direct current power to the alternating current electronic trip circuit.
