That 1200 A frame with the E.DIP LS/I electronic trip unit means it's sized for large feeder or main-breaker duty in a 480 V or 600 V distribution panel — think a 750 kVA transformer secondary or a busway feeding multiple motor control centers. ## What the E.DIP LS/I trip unit gives you On a 1200 A frame, Ir typically adjusts from about 0.4x to 1.0x In — so you can set the continuous pickup anywhere from 480 A to 1200 A to match the actual load without changing the breaker. The instantaneous setting is fixed at roughly 10x In (12,000 A) for this variant, which gives good short-circuit protection while avoiding nuisance trips on motor inrush. No short-time delay or ground-fault function here; that's the LSIG version's job. Mounts in a standard MCCB cutout — the XT7H frame uses a fixed front-panel mounting pattern with screw terminals for line and load connections. Three-pole design means it occupies a single unit width in a switchboard or panelboard. The E.DIP trip unit is front-accessible for adjustment; no need to pull the breaker to change settings. Verify the bus bar spacing and lug size match your existing panel layout before ordering. ## Compliance documentation ABB provides RoHS and REACH declarations for the Tmax XT7 series. UL 489 listing and IEC 60947-2 certification are standard on this frame. The specific order code carries CE marking for European installations. Documentation (declaration of conformity, installation manual, time-current curves) is available on request with the RFQ.","metaTitle":"ABB XT7HQ312EEFF000XXX Tmax XT7H MCCB, 1200A, 3P, 600VAC","metaDescription":"ABB XT7HQ312EEFF000XXX Tmax XT7H molded-case breaker, 1200A, 3-pole, 600VAC, E.DIP LS/I trip unit.
