The LSI designation means it provides Long-time (L), Short-time (S), and Instantaneous (I) protection — the three curves you need for feeder and main breaker duty in low-voltage switchgear. The fixed front terminals (F F) simplify panel bus connections without requiring drawout cassette hardware. The 1200 A continuous rating on a 3-pole frame sizes this for main incoming protection in a 480 V or 600 V switchboard section. The EKIP DIP LSI trip unit gives you field-adjustable long-time pickup and delay, short-time pickup and delay (for selective coordination downstream), and a fixed instantaneous pickup. That selectivity headroom is what lets you clear a branch fault without dropping the main bus — the S (short-time) band is the key parameter for coordination studies. UL listing means the breaker carries the UL 489 mark for North American panel acceptance.","metaTitle":"ABB XT7SU312EFFF000XXX XT7S 1200A EKIP DIP LSI 3P F F UL","metaDescription":"ABB XT7SU312EFFF000XXX XT7S 1200A EKIP DIP LSI IN1200A 3P F F UL power circuit breaker.

No pin-compatible drop-in with identical trip curve and terminal style is listed as a direct cross-reference. For a parametric match, compare the 1200 A frame with EKIP DIP LSI trip in other XT7S order codes."},{"question":"What compliance documentation does ABB provide for this breaker?","answer":"The description includes UL marking, indicating UL 489 listing for the North American market.
