General Electric TEY120 Bolt-On Circuit Breaker

General Electric TEY120 Bolt-On Circuit Breaker is a 20-amp, 1-pole protective device designed for bolt-on installation in GE panelboards that accept TEY breakers. It is rated for 277 V AC and 1-phase operation, providing overcurrent protection for a single circuit in a distribution panel. As part of GE's TEY bolt-on family, this breaker mounts to the panel bus via a bolt-on connection, offering a solid electrical contact and straightforward serviceability in compatible GE load centers. The TEY120's 20 A rating identifies the maximum current it will interrupt under normal conditions before tripping, helping protect wiring and devices on the protected branch. When installed in the appropriate GE panel, it contributes to safe electrical distribution by isolating faults in a single line without affecting other circuits. 277 V systems are common in commercial and some industrial lighting and distribution installations.
