Does this Tmax XT breaker replace older GE Spectra series breakers?
Yes, the ABB SACE Tmax XT family, including the XT1 frame, is the direct replacement for legacy GE Spectra RMS breakers when upgrading to ReliaGear neXT panelboards or using ABB retrofit kits.
Does this breaker provide equipment ground fault protection?
No, the XT1HU3040AYD000XXX features an LI (Long-Time, Instantaneous) trip unit. It provides overload and short-circuit protection but does not include integrated ground fault (G) protection.
