It carries the EKIP DIP LS/I electronic trip unit with L (long-time) and S (short-time) protection plus I (instantaneous) — a common choice for feeder or main breaker duty in industrial switchboards where selectivity and adjustable trip curves are needed. 400 A at 600 VAC means this breaker handles a 400 A continuous load on a 600 V class system. The 3-pole configuration covers three-phase circuits. That means you can coordinate downstream breakers without swapping trip units. The LS/I variant omits ground-fault protection, so if your panel requires GF, you need the EKIP G version instead. UL and CSA listed per the order code suffix — the FF indicates UL/CSA marking. That covers North American installations requiring a listed branch-circuit or feeder breaker.","metaTitle":"ABB XT5HU340AEFF000XXX Molded Case Breaker, 400 A, 3-Pole, 6","metaDescription":"ABB XT5HU340AEFF000XXX molded case circuit breaker, 400 A, 3-pole, 600 VAC, EKIP DIP LS/I trip unit, UL/CSA.
