Westinghouse PA31600PF Tri-Pac Circuit Breaker

The Westinghouse PA31600PF TRI-PAC Circuit Breaker is a three-pole, 1600 A molded-case power circuit breaker designed for high-capacity industrial power distribution and motor protection, rated 600 V with thermal-magnetic/electronic protection and a TRI-PAC electronic trip unit. It is intended for fixed-mount installations in switchgear, motor control centers, and distribution panels, supporting 50/60 Hz three-phase systems for overcurrent and short-circuit protection in industrial-duty service. Typical applications include manufacturing facilities, industrial automation, HVAC equipment, and other power distribution or motor-control environments where high-current circuit protection is required; common replacements listed are Eaton Magnum DS 1600A, Square D Masterpact NW16, and Siemens WL1600 Power Circuit Breaker.
