The Ekip Dip LSI trip unit gives you long-time, short-time, and instantaneous pickup adjustments, so you can coordinate selectively with downstream breakers. At 1200 A and 65 kA SCCR, this breaker handles main incoming protection for a 480 V switchboard feeding motor control centers or large lighting panels. The UL 100% rating means it can carry full rated current continuously without derating — a real advantage in a warm enclosure where a standard 80%-rated breaker would need to be oversized. Front terminals simplify bus-bar or cable connections in a lineup; the drawout version (not this fixed-mount variant) would add cassette-style extraction for maintenance isolation.","metaTitle":"ABB XT7HU312EFFF000XXX SACE XT7H MCCB, 1200 A, 65 kA","metaDescription":"ABB XT7HU312EFFF000XXX molded case circuit breaker, 1200 A, 3-pole, 65 kA interrupting rating at 480 VAC.

The XT1NU3090AFF000XXX is a 90 A, 3-pole breaker in a smaller package. You cannot drop the XT7H into a panel cutout or bus-bar arrangement sized for an XT1 without rewiring and re-drilling the mounting plate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/XT7HU312EFFF000XXX","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/XT7HU312EFFF000XXX when reusing this data.
