Product FAQs
7 answersWhich panelboards and switchboards are compatible with the XT5NU360BBFF3XXX?
This breaker is designed for use in ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and ABB SACE Tmax XT enclosures.
What wire sizes are accepted by the lugs on this 600A breaker?
The factory-installed lugs accept two conductors per phase, ranging from 2/0 AWG to 500 kcmil. Ensure proper torque specifications are followed during installation.
How does the thermal-magnetic trip unit operate on the XT5NU360BBFF3XXX?
It features a TMA trip unit with adjustable settings for both long-time thermal and instantaneous magnetic protection. This allows precise coordination for your specific load requirements.
Can this XT5 breaker be used in DC electrical systems?
Yes, it is rated for DC applications with interrupting capacities of 35kA at 250VDC, 25kA at 500VDC, and 16kA at 600VDC.
Does this ABB Tmax XT5 breaker replace older GE models?
The SACE Tmax XT series, including the XT5 frame, is the direct replacement for legacy General Electric Spectra RMS breakers. It integrates into modern ReliaGear assemblies that replaced the older GE lines.
How is the XT5NU360BBFF3XXX mounted within an enclosure?
This is a unit-mount circuit breaker, meaning it bolts directly to the backpan or mounting plate of the enclosure or switchboard rather than plugging into a busbar.
What is the maximum fault current this breaker can safely interrupt at 480VAC?
The normal interrupting tier rating for this XT5 frame provides a maximum interrupting capacity of 35kA at 480VAC. Always verify the available fault current at the installation point does not exceed this value.
