Product FAQs
5 answersWhat is required to install this breaker in a ReliaGear neXT panelboard?
While the XT4HU3150EYJ000XXX is compatible with ReliaGear neXT panelboards, it requires a specific plug-in mounting kit or hardware assembly designed for the XT4 frame to properly connect to the panel bus.
How does the LSI electronic trip unit benefit panel builders?
The Ekip Dip LSI trip unit allows precise adjustments for Long-Time, Short-Time, and Instantaneous protection. This adjustability makes it easier to achieve selective coordination with upstream and downstream breakers in complex electrical systems.
Are the lugs on the XT4HU3150EYJ000XXX rated for aluminum wire?
Yes, the factory-installed lugs are dual-rated for both copper and aluminum conductors. They accept wire sizes from 4 AWG up to 300 kcmil.
Can I use the XT4HU3150EYJ000XXX to replace a legacy GE Spectra breaker?
The ABB SACE Tmax XT series replaces the legacy GE Spectra RMS line, but they are not physically identical. You will need a specific retrofit kit to install this XT4 breaker into an existing Spectra panelboard or switchboard.
Does this breaker provide ground fault protection?
No, the XT4HU3150EYJ000XXX features an LSI trip unit, which covers Long-Time, Short-Time, and Instantaneous overcurrents. It does not include the Ground Fault (G) function. If equipment ground fault protection is required, an LSIG trip unit model must be sourced instead.
