Product FAQs
7 answersDoes the XT5HU360BBYN000XXX replace older GE circuit breakers?
Yes. Following ABB's acquisition of GE Industrial Solutions, the Tmax XT5 series is the direct replacement for legacy GE Spectra RMS SG600 frame circuit breakers. Retrofit kits are available to install this breaker into existing Spectra panelboards and switchboards.
What equipment is the XT5HU360BBYN000XXX designed to be installed in?
This unit mount molded case circuit breaker is designed for use in ABB and GE ReliaGear neXT panelboards, switchboards, and motor control centers.
What does the H in the XT5H frame designation indicate?
The H indicates a High interrupting capacity. For this specific 600A breaker, it provides an interrupting rating of 65kAIC at 480VAC and 35kAIC at 600VAC.
How does the thermal magnetic trip unit on this breaker operate?
The XT5HU360BBYN000XXX features a TMA (Thermal Magnetic Adjustable) trip unit with LI functions. This allows you to adjust both the long time (thermal) settings for overload protection and the instantaneous (magnetic) settings for short circuit protection to coordinate with your specific system requirements.
Can the XT5HU360BBYN000XXX be used in DC electrical systems?
Yes, this breaker is rated for both AC and DC applications. It supports up to 600VDC, providing a 70kAIC interrupting rating at 250VDC, 50kAIC at 500VDC, and 35kAIC at 600VDC.
What are the wire size requirements for the lugs on this 600A breaker?
The included lugs accept two conductors per phase, accommodating wire sizes from 2/0 AWG up to 500 kcmil. The terminals are rated for both copper and aluminum conductors.
What maintenance is required for the thermal magnetic trip unit?
Standard maintenance includes periodically exercising the breaker by manually toggling it on and off to keep the mechanical linkages free of dust and debris. You should also verify that the adjustable thermal and magnetic dials remain set to the values specified by your coordination study.
