This is a fixed (non-withdrawable) version with front terminals, UL listed for North American panel builds. The 1000 A frame is the physical platform — it determines the mounting footprint, busbar spacing, and lug size. The EKIP DIP LSI trip unit is what makes this breaker selectable: L (long-time) sets the thermal pickup for overloads, S (short-time) provides a delayed trip for moderate faults, and I (instantaneous) clears high faults in under a cycle. The DIP-switch adjustability means you commission the protection settings on the panel floor, not at the factory. Three-pole configuration suits three-phase power distribution, motor feeder, or main breaker duty in a UL 489 panel. ## Deployment context This breaker mounts into a standard switchboard or panelboard enclosure — it is not a DIN-rail device. The fixed-mount version is bolted directly to the bus, so plan for a dedicated mounting position and access to the front terminals for cable or busbar connection. The UL listing covers North American installations; the same part carries IEC ratings for global projects. For a 1000 A main or large feeder, factor in the physical space — roughly the width of a 3-pole frame at that rating — and the required clearance for arc-flash boundaries per NFPA 70E.","metaTitle":"ABB XT7SU310DFFF000XXX XT7S 1000A EKIP DIP LSI, 3P","metaDescription":"ABB XT7SU310DFFF000XXX molded case circuit breaker, XT7S 1000A frame, EKIP DIP LSI trip unit, 3-pole.
