ABB / General Electric TEYL3125B Molded Case Circuit Breaker

It is engineered for direct branch mounting in GE A-Series and Pro-Stock lighting panelboards. The breaker bolts directly to the interior copper or aluminum bus to distribute power safely.

In the GE TEY family, the letter suffix denotes the breaker's maximum interrupting capacity. The 'L' indicates this is the high-interrupting version, fully rated to safely clear a 65kA fault on grounded 480Y/277VAC systems, compared to the standard TEYD or TEYH models which have lower fault ratings.

The TEY series utilizes a compact, one-inch-wide-per-pole frame size. As a three-pole device, it will occupy exactly three inches of bus space inside your panel enclosure.

Yes, the TEYL3125B is rated as suitable for reverse feed. This allows panel builders and electricians to use it flexibly in main, sub-feed, or generator applications where power flows in the opposite direction.

Yes, the TEYL series features a current-limiting construction that responds quickly to short-circuit faults. This design restricts let-through energy, which helps simplify upstream selective coordination and provides increased arc flash protection.

While primarily designed to bolt onto a panelboard bus, the TEYL3125B can be converted for use as a standalone lug-to-lug breaker by installing a separate GE bolt-on mounting base accessory.

Yes, it comes equipped with factory-installed mechanical lugs on the load side that accept either copper or aluminum conductors. The line side secures directly to the panelboard bus via a standard bolt-on connection.

Yes. Following ABB's acquisition of General Electric's Industrial Solutions division, you may receive this exact component with either GE or ABB branding on the label. The physical breaker and panelboard compatibility are identical.
