About ABB

ABB's own North American breaker lines are Tmax (molded case) and Emax (air circuit breakers). Since 2018 ABB also owns GE Industrial Solutions, so GE Spectra, Record Plus, and EntelliGuard are ABB products too. Those live on our GE page.

Tmax XT units turn up mostly in newer OEM equipment, data center gear, and solar balance-of-system panels.

Read the catalog number

Tmax XT catalog numbers read frame, interrupting letter, U for the UL version, poles, then amps. XT1HU3020 is XT1, H, 3-pole, 20A. On XT5 and larger the amps are written in tens: XT5NU340 is a 3-pole 400A unit.

The letter after the frame number is the interrupting class (N, S, H, L, V and so on). Higher classes cost more new and carry more used.

Tmax and Emax trip units (Ekip) are modular. Photograph the trip unit and any modules fitted.
