Built for heavy-duty commercial and industrial applications, the XT5LU360BBYN000XXX provides reliable overcurrent protection in a 3-pole configuration. This 600A unit-mount breaker is part of ABB's advanced SACE Tmax XT5L frame series. It installs into ReliaGear neXT panelboards, ReliaGear SB switchboards, and standard Tmax XT enclosures. For facility upgrades, it serves as a cross-reference for discontinued Tmax T5L 600A Electronic and Spectra RMS SG600 units, featuring an adjustable trip.
Can the XT5LU360BBYN000XXX be used to replace legacy GE Spectra SG600 circuit breakers?
Yes. As part of the ABB SACE Tmax XT series, this XT5L frame breaker is the direct successor to the discontinued GE Spectra RMS SG600 series. It can be installed in existing Spectra panelboards and switchboards using the appropriate ABB Tmax XT retrofit kits.
Which panelboards and enclosures are compatible with this 600A XT5L breaker?
This unit-mount breaker is designed for installation in ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and standard ABB SACE Tmax XT enclosures.
What wire sizes and materials are accepted by the standard lugs on the XT5LU360BBYN000XXX?
The factory-installed lugs accept two conductors per phase, ranging from 2/0 AWG to 500 kcmil. They are rated for both aluminum and copper wiring.
How does the adjustable thermal-magnetic trip unit function on this breaker?
The trip unit allows you to independently adjust both the Long-Time (thermal) and Instantaneous (magnetic) trip settings. This provides precise tuning for overcurrent and short-circuit protection based on your specific load requirements.
Is this XT5L breaker suitable for DC applications?
Yes. In addition to its AC ratings, this breaker is rated for use in DC systems, providing up to 50kA of interrupting capacity at 600VDC.
Does this breaker require specific hardware for panelboard installation?
Yes. While it is a unit-mount breaker designed for panel connections, installing it into ReliaGear neXT or legacy Spectra boards requires the specific mounting hardware or retrofit kits designed for those bus systems.
