Westinghouse Electric BR120 Plug In Circuit Breaker

The Westinghouse BR120 Plug-In Circuit Breaker is a 20A, 240V, 1-pole, 1-phase thermal-magnetic protection device designed for plug-in panel installations in industrial and commercial power distribution systems. It provides overload and short-circuit protection for branch circuits and is intended for BR-style load centers and panelboards, supporting continuous operation in demanding environments such as manufacturing facilities, HVAC electrical systems, and other industrial equipment. Maintenance technicians and electricians typically use it for panel upgrades, electrical maintenance, and replacement applications, and it is commonly replaced by Eaton BR Series, Siemens Plug-In, or Square D Homeline breakers when compatible.
