Westinghouse 2609D39G24 FB Breaker Shunt Trip

The Westinghouse 2609D39G24 FB Breaker Shunt Trip is a shunt-trip accessory for Westinghouse FB circuit breakers, identified by part number 2609D39G24, designed to be installed in Westinghouse FB panels or enclosures to provide remote-trip capability and to support centralized safety and protection schemes. As a remote tripping device, it responds to an external electrical signal to trip the breaker, enabling a fast, controlled interruption of power in response to safety commands, alarm systems, or automation logic, while preserving the integrity of the main protection coordination. The 2609D39G24 designation identifies this module for replacement or compatibility checks, helping technicians confirm correct matching within Westinghouse FB systems and facilitating maintenance or part substitution. Typical applications include electrical installations where remote shutdown capability is required to safeguard equipment and personnel, and where Westinghouse FB breakers serve as the primary protection device. It functions as a discrete module within the protection scheme, providing remote actuation without altering the fundamental operation of the main breaker.
