Product details

The ABB XT4HQ3250EFF000XXX is a Tmax XT4H molded case circuit breaker rated for 250 A continuous at 480 VAC, 3-pole configuration. The 65 kA interrupting rating at 480 VAC means this breaker can safely clear a bolted fault up to that level without upstream coordination failure — critical for main or feeder duty in a distribution panel where the available fault current is known to be high.

Sourcing and Lifecycle

This part carries a current production lifecycle status. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.

Mounting and Integration

Panel-mounted design suits switchboard or enclosed MCCB installations. The XT4 frame accepts standard ABB plug-in or fixed mounting accessories; verify the specific terminal kit and arc-chute orientation against the panel cutout before committing the BOM line.

Frequently asked questions

Where can I buy XT4HQ3250EFF000XXX and how do I get a price?

Sourced and quoted to order against an RFQ through independent distribution channels. Submit an RFQ for current availability and pricing confirmed at quote time.

What is XT4HQ3250EFF000XXX's listed amps (250) on this component line?

The continuous current rating is 250 A at 480 VAC, 3-pole.

Will XT4HQ3250EFF000XXX drop into a panel that was specified around XT5NU340ABNF000XXX without rewiring?

No. The XT5NU340ABNF000XXX is a 400 A, 690 VAC frame — larger physical footprint, different bus spacing, and higher interrupting capacity. The XT4H 250 A unit will not mechanically or electrically interchange without panel rework.
