Product FAQs
6 answersAre lugs included with the XT1NU3015AAA000XXX?
Yes, this breaker comes standard with front terminals that accept 14 AWG to 1/0 AWG copper wire.
What does the 'N' in the XT1NU3015AAA000XXX part number indicate?
The 'N' designates the interrupting capacity level as Normal, which corresponds to a 25kAIC rating at 480VAC for the XT1 frame.
What does the 'U' in the catalog number mean?
The 'U' indicates that the breaker is UL 489 listed for use in North American markets, distinguishing it from IEC-only versions of the Tmax XT series.
Can the XT1NU3015AAA000XXX be mounted on a DIN rail?
While this breaker is configured for standard unit mounting, the ABB Tmax XT1 frame can be adapted for 35mm DIN rail installation using a separate mounting bracket accessory.
Is the trip unit on this breaker adjustable?
No, it features a TMF (Thermal Magnetic Fixed) trip unit. Both the long-time thermal protection and instantaneous magnetic protection thresholds are fixed and cannot be adjusted in the field.
What equipment is this breaker designed for?
It is designed for use in ABB SACE Tmax XT panelboards and switchboards. It is not a direct plug-in replacement for older GE Spectra RMS or Record Plus frames without specific retrofit hardware.
