Product FAQs
6 answersWhich panelboards are compatible with the XT4HU3150BYJ000XXX?
This breaker is designed for use in ABB ReliaGear neXT panelboards, switchboards, and SACE Tmax XT panelboards. It features a unit mount design, meaning it bolts directly to the mounting plate or chassis rather than plugging onto a busbar.
How do the adjustable thermal and magnetic trip settings work on this breaker?
The thermal magnetic trip unit allows you to adjust both the long-time (L) overload protection and the instantaneous (I) short-circuit protection. This adjustability lets you fine-tune the breaker's response curve to match the specific load characteristics and coordination requirements of your electrical system.
What does the H in the XT4HU3150BYJ000XXX part number signify?
The H indicates the interrupting capacity tier of the XT4 frame. In the SACE Tmax XT series, H stands for High interrupting capacity, which provides a 65kA rating at 480VAC and a 150kA rating at 240VAC.
What type of wire can be used with the lugs on this 150A breaker?
The factory-installed lugs accept wire sizes from 4 AWG up to 300 kcmil. The terminals are rated for both copper (Cu) and aluminum (Al) conductors.
Can this ABB Tmax XT breaker be used to replace older GE circuit breakers?
ABB acquired GE Industrial Solutions and introduced the Tmax XT series alongside ReliaGear neXT panelboards to replace legacy GE lines like the Spectra RMS series. However, unit mount breakers require specific mounting hardware, so you must verify chassis compatibility or use a retrofit kit when upgrading older GE switchboards.
Is the XT4HU3150BYJ000XXX rated for DC applications?
Yes, this breaker is rated for both AC and DC systems. It provides a 50kA interrupting capacity at 250VDC and a 65kA interrupting capacity at 600VDC, making it suitable for various industrial DC applications.
