Product FAQs
5 answersWhat panelboards are designed to accept the XT1HU3020AFD000XXX?
This unit mount breaker is designed for integration into ABB ReliaGear NeXT panelboards and ReliaGear SB switchboards. Installation into these systems typically requires the appropriate ReliaGear mounting hardware or module kits.
Is the trip unit on this 20A Tmax XT breaker adjustable?
No. This specific model features a fixed thermal and fixed magnetic (TMF) trip unit. Both the long-time overload and instantaneous short-circuit protection settings are factory set and cannot be adjusted in the field.
What does the H in the XT1HU3020AFD000XXX part number indicate?
The H designates the interrupting capacity tier for this SACE Tmax XT1 frame. It indicates a High interrupting rating, which provides 65kA of fault current protection at 480VAC.
What wire sizes are supported by the standard lugs on this breaker?
The factory-installed lugs accept wire gauges ranging from 10 AWG to 2/0 AWG. Always ensure you torque the terminal screws to the manufacturer specifications printed on the breaker faceplate during installation to prevent thermal issues.
Can this unit mount breaker be converted to a plug-in configuration?
The XT1HU3020AFD000XXX is supplied as a fixed, unit mount breaker. Converting it to a plug-in configuration is possible but requires purchasing a separate conversion kit and a compatible plug-in base assembly.
