Product details

It is a 3-pole unit with UL and CSA approvals, making it suitable for North American panel builds and export machinery that requires those marks. The lifecycle stage is listed as current, meaning the manufacturer still supports this order code for new installations and replacements.

For a panel builder or site electrical engineer, that 100 A sets the maximum load on the downstream conductors and equipment — size the feeder cable and downstream bus for at least that ampacity. The XT4H 250 frame itself is rated for higher currents (up to 250 A), so if the load grows, the trip unit can be swapped without replacing the entire breaker, provided the interrupting rating and SCCR still coordinate upstream. The EKIPLSI trip unit is an electronic, LSIG (long-time, short-time, instantaneous, ground-fault) type. The ground-fault element is built in, so no separate GFCI module is needed for equipment ground-fault protection where code requires it.

Deployment context

The UL/CSA listing means it passes North American short-circuit testing and can be specified without a separate UL listing letter for most panel shops.

Frequently asked questions

What is the closest pin-compatible alternative to XT4HU3100FFF000XXX?

Within the XT4H 250 frame, the closest alternative would be a unit with a different trip current rating or a different trip unit type (e.g., EKIP G or thermal-magnetic). The frame and mounting footprint are shared across the XT4H 250 family, so swapping trip units or ordering a different amp rating is a form-fit-function change without re-paneling.

How do I get current pricing and availability for XT4HU3100FFF000XXX?

The part is sourced to order against an RFQ through independent distribution. Submit a request for quote to confirm current pricing and availability — these are confirmed at quote time and vary with market conditions.

What compliance documentation does this brand provide for XT4HU3100FFF000XXX?

ABB provides UL and CSA certification for this unit, as indicated in the description. RoHS and REACH compliance documentation is typically available from ABB upon request for the XT4 series.
