Product details

This is the current-production variant — lifecycle stage is marked current, meaning ABB still manufactures it as an active catalog line.

The TMF trip unit is a fixed thermal-magnetic design — no interchangeable trip blocks. That simplifies spares stocking but means the breaker is dedicated to its 250 A rating. For panel builders, the XT4H frame is a standard DIN-rail mount, fitting into the same cutout as other XT4 variants.

Deployment context

The 250 A TMF rating suits it for feeder protection or large motor branch circuits where a fixed trip curve is acceptable.

Frequently asked questions

Where can I buy XT4HQ3125AFF000XXX?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead time is published here.

What is the closest alternative to XT4HQ3125AFF000XXX in the XT4 family?

Within the XT4H frame, the primary differentiator is the trip unit. The TMF is fixed at 250 A; an interchangeable electronic trip unit (XT4H 250 Ekip) would be the functional alternative if adjustable trip settings are needed. No pin-compatible drop-in exists — the trip unit type is integral to the breaker.
