Panel-mounted — no DIN-rail adapter. The XT4 frame uses a fixed rear-panel mounting pattern; the front flat terminals accept bus bar or cable lugs. For a panel-builder, that means the breaker occupies a dedicated cutout or sub-panel, not a DIN rail slot alongside contactors and relays. Verify the mounting hole pattern against the existing panel layout before committing the BOM.","metaTitle":"ABB XT4NU3250GFF000XXX Molded Case Breaker, 250A, 3P, 480V","metaDescription":"ABB XT4NU3250GFF000XXX molded case circuit breaker, 250A, 3-pole, 480VAC.
