Product FAQs
6 answersWhat panelboards are compatible with the XT1SU3100AFF000XXX?
This breaker is designed for use in ABB ReliaGear neXT panelboards, ReliaGear RQ panelboards, and ReliaGear SB switchboards. Proper mounting hardware or adapter kits are required depending on the specific panel configuration.
Are the thermal and magnetic trip settings adjustable on this breaker?
No. This model features a TMF (Thermal Magnetic Fixed) trip unit. Both the long-time thermal protection and instantaneous magnetic trip thresholds are factory-set and cannot be adjusted in the field.
What does the 'S' in the XT1S nomenclature indicate?
In the ABB SACE Tmax XT series, the 'S' designates the Standard interrupting capacity tier. For the XT1 frame under UL standards, this provides a 35kAIC rating at 480VAC.
What type of line and load connections are standard on this model?
The 'FF' in the catalog number indicates the breaker comes standard with front terminals for both the line and load sides. It is a unit-mount, bolt-on breaker that accepts standard ABB front terminal lugs.
Can the Tmax XT1 replace legacy GE Spectra breakers?
The ABB Tmax XT series is the designated upgrade path for legacy GE Spectra RMS and Record Plus breakers. However, they are not physically identical. Retrofitting an XT1 into an older GE enclosure requires a specific ABB retrofit kit to adapt the mounting and bus connections.
Can internal accessories be added to this XT1 breaker?
Yes, the SACE Tmax XT1 frame supports a range of field-installable internal accessories, including shunt opening releases (SOR), undervoltage releases (UVR), and auxiliary contacts (AUX). These install into dedicated accessory slots under the front cover.
