The 65 kA interrupting rating at 480 VAC means this breaker can safely clear a bolted fault up to that level without upstream coordination failure — critical for main or feeder duty in a distribution panel where the available fault current is known to be high. ## Sourcing and Lifecycle This part carries a current production lifecycle status. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time. ## Mounting and Integration Panel-mounted design suits switchboard or enclosed MCCB installations. The XT4 frame accepts standard ABB plug-in or fixed mounting accessories; verify the specific terminal kit and arc-chute orientation against the panel cutout before committing the BOM line.","metaTitle":"ABB XT4HQ3250EFF000XXX XT4H 250 A MCCB, 3-Pole, 65 kA","metaDescription":"ABB XT4HQ3250EFF000XXX XT4H molded case circuit breaker, 250 A, 3-pole, 480 VAC, 65 kA interrupting rating.
