Product FAQs
5 answersWhat panelboards are compatible with the XT4HU3175AYJ000XXX?
This unit mount breaker is designed for use in ABB ReliaGear neXT panelboards and compatible switchboards.
What wire sizes are accepted by the standard lugs on this breaker?
The included lugs accept wire gauges from 4 AWG up to 300 kcmil and are rated for both copper and aluminum conductors.

No. This specific breaker features a thermal magnetic trip unit with fixed thermal and fixed magnetic settings for long-time and instantaneous protection.
How does this breaker connect to the bus or conductors?
It features front flat terminal connections and is configured for unit mounting. This means it bolts directly to the mounting surface or chassis rather than plugging into a busbar.

The Tmax XT series is integrated into the ABB ReliaGear neXT architecture. It is not a direct replacement for legacy GE Spectra or A-Line panelboards without specific retrofit kits or chassis upgrades.
