ABB | UL / CSA MOLDED CASE CIRCUIT BREAKERS
Product overview
ABB SACE Tmax XT UL/CSA circuit breakers provide low-voltage power-distribution protection with thermal-magnetic or Ekip electronic trip units. Choose current first or select a frame; poles, interrupting class and trip unit resolve an exact U.S./Canada product type and ABB order code.
Key features
- XT1 through XT7 and XT7 M fixed circuit breakers, up to 1200A.
- AIC selection is explicitly stated at 480V AC; other voltage ratings remain device-specific.
- Exact base-breaker references with separate, frame-matched electrical and mechanical accessory order codes.
