Product FAQs
7 answersWhich panelboards and switchboards are compatible with the XT1NU3030AYD000XXX?
This XT1 frame breaker is designed for use with ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and Tmax XT enclosures. It utilizes a unit mount configuration rather than a plug-in design.
Is this breaker suitable for direct current (DC) systems?
Yes, the XT1NU3030AYD000XXX is rated for DC applications up to 500VDC, providing a 35kA interrupting capacity at both 250VDC and 500VDC.
What wire gauge range do the factory lugs on this breaker accept?
The included lugs accommodate wire sizes from 10 AWG up to 2/0 AWG. Ensure proper torque specifications are followed during installation as outlined in the ABB Tmax XT instruction manual.
Are the thermal and magnetic trip settings adjustable on this model?
No, this specific breaker features a fixed thermal and fixed magnetic trip unit. If your application requires adjustable trip settings, you will need to select an XT breaker equipped with an Ekip DIP or Ekip Touch electronic trip unit.
What does the N designation indicate in the XT1NU3030AYD000XXX part number?
The N specifies the interrupting capacity tier for the Tmax XT family. For the XT1 frame, the N tier provides a 25kAIC rating at 480VAC and 50kAIC at 240VAC.
Can the Tmax XT1 series be used to replace legacy General Electric breakers?
Yes, following ABB's acquisition of GE Industrial Solutions, the SACE Tmax XT family replaces legacy GE Spectra RMS and Record Plus molded case circuit breakers. The XT1 frame specifically serves as a modern replacement for the GE Record Plus FD frame and Spectra SE frame in many applications.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time (L) protection against overloads and Instantaneous (I) protection against short circuits. Both of these settings are fixed on this specific model.
