The ABB XT7HU310EGFF000XXX is a 1200 A molded-case circuit breaker from the XT7H series, with an electronic trip unit (E.DIP) providing LSIG protection and a RP1000 rating plug. The description on record reads XT7H 1200 E.DIP LSIG RP1000 3PUL, confirming a three-pole, 1200 A frame with full selective coordination capability.
This breaker is sized for main or feeder protection in switchboards and panelboards where 1200 A of continuous current and LSIG selectivity are required. The E.DIP trip unit allows field-adjustable settings for long-time pickup and delay, short-time pickup and delay (with I²t on/off), instantaneous pickup, and ground-fault pickup and delay — all accessible without opening the breaker cover.
