Product FAQs
7 answersWhich panelboards and switchboards are compatible with the XT4LU3150BYJ000XXX circuit breaker?
This 150A breaker is designed for seamless integration with ABB ReliaGear neXT Panelboards and ReliaGear SB Switchboards.
What conductor sizes and materials are accepted by the factory lugs on this breaker?
The included lugs accommodate 4 AWG through 300 kcmil copper (Cu) or aluminum (Al) wire, providing flexibility for various conduit and conductor routing requirements.
How does the adjustable trip unit operate on this XT4 breaker?
It features a thermal-magnetic trip unit with adjustable long-time (L) and instantaneous (I) settings. This allows electricians to fine-tune both overload and short-circuit protection to match specific load requirements.
What is the maximum interrupting capacity of this breaker in 480V commercial systems?
In 480VAC systems, this breaker provides a high interrupting capacity of 100kA. It also scales up to 200kA for 240VAC applications, making it suitable for environments with substantial available fault currents.
What mounting configuration does this Tmax XT4 breaker use?
It utilizes a unit mount configuration, meaning it is designed to be bolted directly to the chassis or mounting pan of compatible enclosures, rather than plugging into a busbar.
Is the XT4LU3150BYJ000XXX rated for use in DC power systems?
Yes, this breaker is fully rated for direct current applications. It provides an interrupting capacity of 85kA at 250VDC and 75kA at 600VDC, making it suitable for specialized industrial DC loads.
What frame size is the XT4LU3150BYJ000XXX built on?
This breaker is part of the SACE Tmax XT family and is built on the XT4 frame. This standardized frame size helps panel builders ensure proper fitment and accessory compatibility across multiple amperage ratings.
