Product FAQs
6 answersWhich panelboards are compatible with the XT1HU3090AFD000XXX?
This unit mounts directly into ABB SACE Tmax XT panelboards and switchboards. As a unit mount breaker, it fastens directly to the enclosure backpan or mounting plate rather than plugging into a busbar.
What wire sizes are accepted by the lugs on this 90A breaker?
The factory lugs accept conductors ranging from 10 AWG to 2/0 AWG. Always apply the manufacturer specified torque when terminating cables to ensure a secure and compliant connection.
Can the thermal or magnetic trip settings be adjusted on this model?
No, this specific Tmax XT1 breaker features a thermal magnetic trip unit with fixed thermal and fixed magnetic settings. It provides standard long-time and instantaneous (LI) protection without adjustable dials.
Is this Tmax XT1 breaker suitable for DC power systems?
Yes, it is rated for direct current applications up to 500 VDC. It delivers a 50kA interrupting capacity at both 250 VDC and 500 VDC.
How does the ABB and General Electric branding apply to this breaker?
ABB acquired GE Industrial Solutions, integrating their product lines. The SACE Tmax XT series is an ABB global platform often utilized in new installations and for modernizing legacy GE switchboards.
What is the maximum fault current this breaker can safely clear?
This high-interrupting breaker can safely clear fault currents up to 100kA at 240VAC and 65kA at 480VAC. Ensure your system's available fault current does not exceed these limits.
