ABB Tmax XT

ABB Tmax XT molded case circuit breakers

ABB Tmax XT MCCBs protect commercial and industrial distribution systems against overloads and short circuits. The range supports higher current and breaking-capacity requirements than typical miniature circuit breakers.

Compare XT1, XT3 and XT5 models by pole configuration, rated current, breaking capacity and trip-unit requirements. Correct selection depends on system fault level, cable capacity, load profile and selectivity. For broader options, see all molded case circuit breakers.
