The TMA trip gives you thermal adjustment for overloads and fixed magnetic pickup for short-circuits. On a 100 A setting in a 250 A frame, you have headroom for high inrush loads without nuisance tripping — common on motor or transformer feeders where the starting current exceeds the continuous rating for a few cycles. The 500-1000 VAC rating covers systems common in industrial distribution. The 250 A frame with a 100 A trip means the breaker body handles the short-circuit current while the trip unit protects the downstream conductor at 100 A. UL and CSA listing means the breaker is accepted for use in service entrance equipment and panelboards under NEC and CEC. No special agency review needed for the panel builder.","metaTitle":"ABB XT4NU3100BFF000XXX XT4N 250A Frame MCCB, 100 A TMA, 500-","metaDescription":"ABB XT4NU3100BFF000XXX molded case circuit breaker, XT4N 250A frame, 100 A TMA trip, 500-1000 VAC, 3P, UL/CSA.
