Product FAQs
6 answers
Which panelboards and switchboards are compatible with the XT4HU3200BYJ000XXX?
This breaker is designed for use with ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and SACE Tmax XT panelboards.
What does the LI designation mean for this thermal-magnetic trip unit?
The LI code indicates Long-Time and Instantaneous protection. On this specific XT4 model, both the thermal overload (Long-Time) and magnetic short-circuit (Instantaneous) trip points are adjustable, allowing for precise coordination with your system loads.
Can this ABB XT4 breaker be used in DC electrical systems?
Yes, it is fully rated for direct current applications. It provides an interrupting capacity of 50kA at 250VDC and 65kA at 600VDC, making it suitable for industrial DC controls, battery systems, or solar applications.
What wire sizes and materials do the factory lugs accept?
The included lugs are rated for dual-rated use with both copper (Cu) and aluminum (Al) conductors. They accept wire gauges ranging from 4 AWG up to 300 kcmil.
How is this unit mount breaker installed?
As a unit mount breaker, it bolts directly to the enclosure backpan or mounting surface rather than plugging into a busbar. Electrical connections are then made by landing cables directly into the breaker lugs.
Why is this ABB breaker listed with General Electric as a parent brand?
ABB acquired GE Industrial Solutions. The SACE Tmax XT series is the current generation of breakers used in modern ReliaGear panels, which replaced legacy GE distribution equipment lines.
