The Ekip LSI trip's Short-time pickup and delay settings let you coordinate with downstream breakers on a selective coordination study — something a fixed thermal-magnetic can't do. The fixed front terminal (F F in the code) means the line and load lugs are both on the front face, which simplifies bus-bar layout in a multi-breaker section. Mounts on the standard DIN rail or direct-panel footprint that ABB's XT4 family shares, so the enclosure cutout and bus spacing are consistent across the line. No EOL notice, no last-time-buy window to track. For a sourcing buyer, that means you can commit this code to a BOM without worrying about a forced redesign next year.","metaTitle":"ABB XT4SU3250FFL000XXX XT4S 250 A, Ekip LSI, 3P, UL/CSA","metaDescription":"ABB XT4SU3250FFL000XXX molded case circuit breaker, XT4S 250 A frame, Ekip LSI trip unit, 3-pole, UL/CSA.

The mechanical footprint, terminal arrangement, and UL/CSA listing are shared across the XT4S 250 platform — the difference is only in the trip unit electronics and the order code suffix."},{"question":"Where can I buy XT4SU3250FFL000XXX and how is it quoted?","answer":"This breaker is sourced to order through independent distribution.
