ABB TEYL3080B Circuit Breaker

This breaker is specifically designed for installation in GE (now ABB) A-Series lighting panelboards. It bolts directly to the panelboard bus.

The letters in the TEY family denote the short-circuit interrupting rating. While they share the same physical dimensions, the standard TEY provides 14kAIC at 480/277VAC, the TEYF provides 18kAIC, the TEYD offers 25kAIC, the TEYH offers 35kAIC, and the TEYL is the highest tier, providing 65kAIC at 480/277VAC.

The TEY breaker family is built on a compact platform requiring 1 inch of width per pole. As a 3-pole device, the TEYL3080B occupies exactly 3 inches of mounting space in the panelboard.

The line side features a bolted connection designed to mount directly to the A-Series panelboard bus. The load side is equipped with mechanical lugs for terminating your branch circuit conductors.

No. The TEYL3080B is strictly rated for grounded 480Y/277VAC systems. It must not be installed on ungrounded or corner-grounded 480V Delta configurations.

Yes. The TEYL series features a current-limiting construction that ensures a rapid response to high-level short-circuit faults. This restricts let-through energy and simplifies upstream selective coordination.

Yes. Although primarily designed as a bolt-on branch breaker for A-Series panelboards, it can be utilized in unit-mount or lug-to-lug installations when fitted to an appropriate 3-pole mounting base accessory.

Yes, provided the panelboard's main bus and overall series rating allow it. The TEYL3080B shares the exact same physical dimensions and bolt-on connection as the TEY, TEYF, TEYD, and TEYH lines. This allows you to easily upgrade a branch circuit's interrupting capacity to 65kAIC without modifying the panel space.

General Electric originally engineered the TEY line for their A-Series panelboards. Since ABB acquired GE Industrial Solutions, this exact breaker is now manufactured and distributed by ABB under the same TEYL3080B catalog number.
