General Electric TEY120 Bolt On Circuit Breaker

The General Electric TEY120 serves as a dedicated bolt-on circuit breaker constructed for secure attachment to compatible GE load center busbars, distinguishing it mechanically from standard plug-in designs. Capable of carrying up to 20 amps of continuous current while managing a nominal voltage of 277 volts, this single-pole unit delivers thermal-magnetic tripping performance to safeguard downstream wiring against short circuits and overloads in single-phase power systems. Installers frequently specify this TEY series component during upgrades for lighting and motor-driven equipment applications where original factory busbar spacing requires a fastened interface instead of a sliding slot connection.

Confirming board busbar alignment prior to tightening the hold-down fastener is essential to ensure consistent torque resistance and proper electrical conductivity throughout the service life of the distribution panel. Strict adherence to the 277-volt rating prevents misuse in incompatible 120-volt residential setups, ensuring the device meets electrical code requirements for branch circuit protection in institutional facilities.
