ABB / General Electric TEYD3045B Miniature Circuit Breaker

No. Although it is part of the broader Q-Line family, the TEYD3045B is a bolt-on breaker specifically designed for commercial GE A-Series lighting panelboards. It will not fit in residential plug-on load centers that require THQL or THQP breakers.

The letter suffix in the frame designation indicates the breaker's short-circuit interrupting rating at 480/277V. The standard TEY is rated at 14kA, the TEYD is 25kA, and the TEYH is 35kA. All share the same physical dimensions and mount into the same A-Series panelboards.

Yes. While it is primarily designed to bolt onto the bus of GE A-Series panelboards, it can be adapted for unit-mount or lug-to-lug installations by utilizing a separate three-pole mounting base.

While the factory lugs are dual-rated for 10-4 AWG copper or aluminum wire, you must apply a manufacturer-approved joint compound (anti-oxidant) to aluminum conductors before termination to prevent oxidation and ensure a secure electrical connection.

Yes, the TEYD frame features a current-limiting construction that allows for full instantaneous selectivity when coordinated with upstream GE breakers, such as the Record Plus or EntelliGuard series.
