Product FAQs
5 answersWhich panelboards are compatible with the XT6HU3600BFU000XXX breaker?
This unit is designed for unit mount installation directly into ABB and GE ReliaGear neXT Power Panelboards, as well as ReliaGear SB Switchboards.
What wire sizes are accepted by the factory lugs on this 600A breaker?
The included lugs accept three conductors per phase, ranging from 2/0 AWG to 400 kcmil. They are rated for both copper and aluminum wiring.
How does the adjustable thermal-magnetic trip unit function on this XT6 breaker?
The LI trip unit allows you to adjust both the long-time (thermal) settings for overload protection and the instantaneous (magnetic) settings for short-circuit protection. This provides precise coordination for your specific load requirements.
Is this breaker suitable for DC applications?
Yes, it is fully rated for DC systems. It provides interrupting capacities of 70kA at 250VDC, 50kA at 500VDC, and 35kA at 600VDC.
Does this ABB Tmax XT breaker replace older GE models?
The SACE Tmax XT family, including the XT6 frame, is the modern replacement for legacy GE molded case circuit breakers. It is designed to integrate seamlessly into the updated ReliaGear ecosystem following ABB's acquisition of GE Industrial Solutions.
