Product details

What you're looking at

XT1NU3030AAA00NXXX is a molded case breaker rated 30 A, 3-pole, 600Y/347 VAC with a 25 kAIC interrupting capacity. Panel-mount construction — no DIN-rail adapter, so plan for a dedicated cutout or sub-panel in the enclosure.

Panel integration

Panel-mount only. No DIN-rail clip. That means the breaker bolts directly to a mounting plate or sub-panel. Verify the cutout dimensions and lug type before the panel build — the 25 kAIC rating may also drive minimum wire size and bending radius for the line-side conductors.

Frequently asked questions

Will XT1NU3030AAA00NXXX drop into a panel wired for XT5NU340ABNF000XXX?

No. The XT5NU340ABNF000XXX is a 400 A frame with different bus-bar spacing and lug sizes. The 30 A XT1NU3030AAA00NXXX requires separate mounting and conductor sizing.

What are the key ratings for XT1NU3030AAA00NXXX?

30 A, 3-pole, 600Y/347 VAC, 25 kAIC interrupting capacity. Panel mount.
