Product FAQs
7 answersWhat panelboards accept the XT4HU3100AFJ000XXX circuit breaker?
This unit-mount breaker is designed to integrate directly with ABB ReliaGear neXT Panelboards, ReliaGear SB Switchboards, and SACE Tmax XT Panelboards.
What wire gauge and conductor material do the lugs support?
The factory-installed lugs accept 4 AWG to 300 kcmil conductors and are dual-rated for both copper (Cu) and aluminum (Al) wire. Ensure you follow standard torque specifications during termination.
Are the long-time and instantaneous trip settings adjustable?
No. The XT4HU3100AFJ000XXX features a fixed thermal-magnetic trip unit (LI). If your application requires field-adjustable trip curves, you must select an XT4 variant equipped with a TMA (Thermal Magnetic Adjustable) or an Ekip electronic trip unit.
What does the "H" in the XT4HU catalog number indicate?
The "H" signifies that this is a High Interrupting tier frame. It provides elevated short-circuit fault protection compared to standard XT4 frames, delivering up to 150kA at 240VAC and 65kA at 480VAC.
Can the XT4HU3100AFJ000XXX be used in DC power circuits?
Yes. While commonly used in AC distribution, this frame is fully rated for DC systems. It provides up to 50kA interrupting capacity at 250VDC and 65kA at 600VDC.
Is this breaker configured for plug-in or fixed mounting?
Out of the box, this SKU is configured as a fixed, unit-mount breaker. Installing it in a plug-in or withdrawable configuration requires a separate moving part conversion kit and a compatible fixed base.
Why is the parent brand listed as both ABB and General Electric?
Following ABB's acquisition of GE Industrial Solutions, the SACE Tmax XT series serves as the modern replacement platform for legacy GE molded case circuit breakers. This unit is manufactured by ABB and is designed specifically for current ReliaGear and Tmax distribution equipment.
