GE TEY125 25A Single-Pole Breaker

This GE TEY125 molded case circuit breaker provides 25 A overcurrent protection for single-phase AC circuits rated at 277/480 V. It features a thermal-magnetic trip unit with a fixed instantaneous setting and a high amp trip point of 575 A. The unit is designed for bolt-on mounting in GE AE lighting panels.

Bolt-On Installation and Lug Termination

The breaker mounts directly onto the panelboard bus using a bolt-on connection that requires a screwdriver or nut driver. A mechanical lug terminal accepts the circuit conductor and must be torqued to the manufacturer specification. The most common issue is an under-torqued lug that leads to overheating or nuisance tripping.

Verify Panel Compatibility and Ratings

Confirm the panelboard is a GE AE lighting panel that accepts TEY series bolt-on breakers. Ensure the system voltage does not exceed 277/480 V AC or 125 V DC and that the available fault current is within the 14 kA interrupting rating at 277 V. The frame size is 125 A, so the panel bus must accommodate that rating.

Questions about this item

How can I verify the breaker is working after installing it in a GE AE lighting panel?

After bolt-on mounting, confirm the handle moves firmly to ON and OFF, measure 277/480V AC across the lug terminal, and check that the thermal-magnetic trip operates at the fixed instantaneous setting of 575 A.

What comes in the box and what must I supply separately?

The package contains the single-pole TEY frame breaker rated 25 A with integrated lug terminals; you must provide the GE AE panelboard, mounting hardware, and supply conductors sized for 14 kA interrupting at 277 V AC.

Which TEY version should I choose for a 25 A single-phase 277 V lighting circuit?

Select the 1-pole TEY model rated 25 A, 277/480 V AC, 125 V DC, with 14 kA AIR at 277 V and fixed 575 A instantaneous trip for standard bolt-on panelboard mounting.
