The thermal-magnetic (TMF) trip unit provides fixed overload and short-circuit protection — no interchangeable trip modules, so the 225 A rating is locked at order. Panel-mount footprint suits retrofit into existing switchboards or new MCC builds where DIN-rail isn't the standard. ## What the 65 kAIC rating means for your panel For branch circuits downstream with lower fault levels, you may be able to step down to a lower AIC frame — but at 225 A, this is likely a main or large feeder breaker.","metaTitle":"ABB XT4HU3225AFF000XXX Molded Case Breaker, 225A, 3P, 480V","metaDescription":"ABB XT4HU3225AFF000XXX molded case circuit breaker, 225A, 3-pole, 480 VAC, 65 kAIC.
