Westinghouse Electric CHFD1020 Circuit Breaker

The Westinghouse CHFD1020 is a 1-pole, 20-amp plug-in circuit breaker designed for industrial and commercial power distribution, providing overload and short-circuit protection with thermal-magnetic interruption and a reset capability. It is compatible with CH series panelboards and load centers and is intended for branch circuits in electrical panels, HVAC systems, lighting circuits, and industrial equipment where interruption and restoration must be reliable. Built in an industrial-duty housing for continuous operation, the CHFD1020 is suited for manufacturing facilities, automation, control panels, and other distribution equipment in which stable electrical operation is essential. Maintenance technicians, electricians, and system integrators commonly use it for panel upgrades, electrical maintenance, and replacement projects in demanding environments. Specifications include a 20 A current rating, 1-pole configuration, plug-in mounting, and thermal-magnetic protection; common replacements include Eaton CH Series, Siemens Plug-In, and Square D circuit breakers. Common usage environments include industrial electrical systems, facility power distribution assemblies, and branch circuits in industrial settings.
