Eaton Circuit Breaker Bases & Accessories

Eaton circuit breaker accessories are designed specifically for use with Eaton circuit breakers and molded case switches in industrial, commercial, and utility power distribution applications. Accessory devices provide valuable control, signaling and remote operation features beyond the standard overcurrent switching functionality delivered by a circuit breaker frame. Accessories are widely used in switchgear, panelboard, motor control center (MCC), generator transfer, and other critical power circuit installations containing Eaton molded case breakers.

Eaton manufactures a broad range of factory-approved circuit breaker accessory products for auxiliary contacts, alarm indicators, shunt trips, undervoltage releases, motor operators, rotary handle and shaft operators, door-coupling accessories, communications interface modules and more. These electrical accessories, also known as internal accessories, breaker options, breaker add-ons, or add-on modules, enable users and automation equipment to indicate or monitor breaker trip status, conduct emergency or automated tripping, and operate remotely as part of a safety interlock, supervisory control, automation control, or machine control system.
