Westinghouse NP28313-F Molded Case Circuit Breaker

The Westinghouse NP28313-F is a 3-pole molded case circuit breaker (AB Circuit Breaker) designed for industrial power distribution, delivering thermal-magnetic fault interruption with a 20 A rating and a 600 VAC / 250 VDC voltage rating in a panel-mount frame. It is suited to three-phase systems in motor control centers, distribution panels, manufacturing equipment, HVAC, and industrial automation, providing branch-circuit and motor protection with a thermal magnetic trip, 50/60 Hz operation, industrial duty rating, and mechanical lug connections for secure terminations. Maintenance teams and system integrators use it for replacement, retrofit projects, preventive maintenance, and upgrades, and common replacements include Square D FA34020 and Siemens BQD320.
