Product FAQs
7 answersWhich panelboards and switchboards accept the XT4LU3200BYJ000XXX breaker?
This XT4 frame breaker is designed for direct integration with modern ABB ReliaGear neXT panelboards and ABB ReliaGear SB switchboards.
Can the XT4LU3200BYJ000XXX replace legacy GE Spectra circuit breakers?
Yes. Following ABB's acquisition of GE Industrial Solutions, the Tmax XT series replaces the legacy GE Spectra RMS series. With the appropriate ABB retrofit kit, this XT4 breaker can be installed in existing GE Spectra panelboards and switchboards to upgrade legacy F-frame breakers.
How does the adjustable thermal-magnetic trip unit function on this XT4 breaker?
This breaker features an LI (Long-Time, Instantaneous) trip unit with adjustable thermal and adjustable magnetic settings. This allows electricians to fine-tune both the overload and short-circuit protection thresholds to match specific load requirements and coordination studies.
What wire sizes and materials are supported by the factory lugs on this breaker?
The included lugs accept both copper and aluminum conductors ranging from 4 AWG up to 300 kcmil, providing flexibility for various conduit and wire pull requirements.
Does this breaker use a plug-in or unit mount configuration?
The XT4LU3200BYJ000XXX is a unit mount circuit breaker. It bolts directly to the mounting surface or backpan, making it suitable for standalone enclosures or specific bolt-on panelboard configurations, rather than plugging into a busbar system.
Can the XT4LU3200BYJ000XXX be reverse fed?
Yes, this breaker is rated for reverse feed applications. This allows power to be supplied to either the top or bottom terminals without compromising the breaker's thermal-magnetic protection capabilities.
Is the XT4LU3200BYJ000XXX suitable for heating, air conditioning, and refrigeration equipment?
Yes, this breaker is HACR rated. It has been tested and approved to handle the specific electrical loads and inrush currents associated with commercial HVAC and refrigeration equipment.
