GE TEY3100 Molded Case Circuit Breaker – 100A – 3-Pole – 480Y/277VAC – 14kAIC @ 480Y/277V – Bolt-On – Q-Line TEY

The General Electric (GE) TEY3100 is a 100A, 3-pole molded case circuit breaker from the Q-Line TEY Series, designed for commercial, industrial, and lighting-panel electrical distribution applications. It features a fixed thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) protection functions for reliable overload and short-circuit protection.

The TEY3100 is designed for 480Y/277VAC grounded distribution systems and uses a compact bolt-on mounting configuration with load-side lug connections. It provides an interrupting capacity of 14kAIC at 480Y/277VAC and up to 65kAIC at 120/240VAC and 240VAC.

The breaker features a non-interchangeable trip unit, quick-make/quick-break operating mechanism, and common trip bar. It is suitable for compatible GE Q-Line lighting panelboards and electrical distribution equipment.

Compatibility

Designed for use with compatible GE Q-Line TEY Series electrical distribution equipment, including GE ASL, AE, and AD lighting panelboards and compatible commercial and industrial control panels.

The TEY3100 is intended for 3-phase, grounded 480Y/277VAC systems and uses a 3-pole bolt-on configuration with load-side lugs. Its fixed thermal-magnetic LI trip unit provides long-time and instantaneous overcurrent protection.

It is suitable for applications including commercial and industrial lighting, HVAC, heating and refrigeration equipment, manufacturing facilities, and electrical distribution systems, where the breaker ratings and panelboard specifications are appropriate.

Always verify the specific panelboard model, breaker series, system voltage, pole configuration, interrupting rating, conductor requirements, and manufacturer-approved application before installation.
