Product details

800A MCCB with Ekip Dip LS/I protection

The ABB XT6HU3800EFF000XXX is a 3-pole molded case circuit breaker rated 800 A continuous on a 600 VAC system, built on the XT6H frame. The Ekip Dip LS/I trip unit provides adjustable long-time and short-time protection with instantaneous override — the standard choice for feeder and main breaker duty in industrial distribution panels. At 800 A and 600 VAC, this MCCB handles the full load of a large motor control center or a transformer secondary. The 3-pole construction covers three-phase systems; the FF suffix indicates the standard fixed-front terminal configuration for panel-mount installations.

The Ekip Dip LS/I trip unit allows field-adjustable long-time pickup (Ir) and short-time pickup (Isd) plus instantaneous (Ii) — critical for coordinating with downstream feeders and avoiding nuisance trips on motor inrush. The 3-pole form factor fits standard panelboard and switchboard mounting arrangements, with line and load lugs sized for the 800 A cable bundle.

Compliance documentation

ABB provides RoHS and REACH declarations for the XT6H series; request them with the RFQ for your quality documentation package.

Frequently asked questions

What is the closest alternative to XT6HU3800EFF000XXX?

Within the same XT6H frame, the Ekip Dip LS/I trip unit is available with different accessory suffixes (e.g., terminal type, rotary handle). The closest functional peer shares the same 800 A frame, 3-pole count, and Ekip Dip LS/I protection — only the accessory configuration differs. Confirm the terminal and mounting requirements before substituting.

Where can I buy XT6HU3800EFF000XXX and get current pricing?

Sourced and quoted to order against an RFQ through independent distribution. Submit a request for current pricing and availability — both are confirmed at quote time.

What is the 800 A rating used for on this breaker?

The 800 A continuous rating makes this MCCB suitable for main feeder protection in industrial distribution panels, large motor control centers, or transformer secondary protection at 600 VAC or less.

What compliance documentation does ABB provide for this MCCB?

The FF UL/CSA marking indicates UL 489 and CSA C22.2 No. 5 listings. ABB also supplies RoHS and REACH declarations on request for the XT6H series.
