Westinghouse Electric GHB2080 Circuit Breaker

The Westinghouse Electric GHB2080 Circuit Breaker is a two-pole, 80-amp device designed for 480/277-volt AC service, giving reliable overcurrent protection for higher-capacity branch circuits in commercial and industrial electrical distribution. As part of the Westinghouse GHB family, the GHB2080 is intended for panel installations that handle 480/277V circuits, providing a two-pole interruption to safeguard conductors, devices, and connected loads. In practical terms, it protects circuits up to 80 amperes, preventing damage from overloads and short circuits by interrupting current flow when fault conditions arise. Typical applications include large-drawer or fixed-panel branch circuits in commercial facilities, data centers, manufacturing floors, and other environments where 480/277V power is distributed. This description reflects the essential characteristics of the GHB2080: a two-pole, 80A circuit breaker for 480/277V service that helps maintain electrical safety and system reliability. When selecting a replacement or upgrade, confirm that the panel supports GHB2080-series breakers and that the bus and mounting align with the system requirements for 480/277V operation.
