Product FAQs
7 answersWhat equipment is compatible with the XT4HU3090AFJ000XXX breaker?
This unit mounts directly into ABB SACE Tmax XT panelboards, switchboards, and compatible standalone enclosures designed for XT4 frame breakers.
What wire sizes are accepted by the standard lugs on this XT4 breaker?
The factory-installed lugs accept copper or aluminum conductors ranging from 4 AWG to 300 kcmil. Ensure proper torque specifications are followed during installation as outlined in the ABB instruction manual.
What does the H in the XT4HU3090AFJ000XXX catalog number indicate?
The H designates this as a High interrupting capacity breaker within the Tmax XT4 family, providing a 65kA fault current rating at 480V AC.
Is the thermal-magnetic trip unit on this 90A breaker adjustable?
No. This specific model features a fixed thermal and fixed magnetic trip unit. Both the long-time overload and instantaneous short-circuit protection settings are factory set and cannot be adjusted in the field.
Does this breaker require a special mounting base or plug-in kit?
No. This is a unit-mount breaker designed for fixed installation. It bolts directly to the mounting surface or chassis and does not use a drawout or plug-in base.
Is the XT4HU3090AFJ000XXX rated for direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for DC applications. It provides up to 50kA interrupting capacity at 250V DC and 65kA at 600V DC.
Can this ABB Tmax XT breaker replace older GE models?
ABB acquired GE Industrial Solutions and integrated many product lines. While the Tmax XT series is the current standard, it may require specific retrofit kits or adapter hardware to replace legacy GE molded case circuit breakers in existing switchboards.
