Product details

Molded case breaker, 30 A, 3-pole — panel-mount fit

The ABB XT1NU3030AAA0A0XXX is a Tmax XT1 molded case circuit breaker rated 30 A continuous, 3-pole, with a 480 VAC maximum operating voltage and an interrupting capacity of 18 kAIC. The UL 80% rated designation means the breaker is listed for continuous loading at 80% of its 30 A frame rating (24 A) without derating, which is the standard for most UL 489 molded case breakers used in commercial and industrial panels.

Panel-mount integration

The breaker is panel-mounted, not DIN-rail — it bolts directly to a backplate or enclosure subpanel. The fixed front flat terminals accept standard lug or bus-bar connections. For a panel OEM, this means planning for a dedicated mounting footprint and torque-specified terminations rather than a snap-on rail.

Frequently asked questions

Who supplies XT1NU3030AAA0A0XXX and how is it quoted for volume purchases?

We supply it through the authorized ABB franchise channel. Submit an RFQ for volume pricing and lead time; availability is confirmed at quote time.

What is XT1NU3030AAA0A0XXX's listed amps and poles?

The breaker is rated 30 A continuous, 3-pole, with a 480 VAC maximum and 18 kAIC interrupting capacity.

Will XT1NU3030AAA0A0XXX drop into a panel specified around XT1NU3090AFF000XXX without rewiring?

No — the peer XT1NU3090AFF000XXX is a 90 A variant in the same Tmax XT1 frame, so the physical footprint and terminal layout are identical, but the 30 A trip unit is fixed and cannot be swapped to match a 90 A load. The panel bus and conductor sizing must match the 30 A rating.
