Description
A highly configurable overcurrent solution, the ABB XT4NU3225FY8000XXX functions as a 3-pole, 225A electronic trip circuit breaker. It leverages microprocessor technology to offer superior accuracy compared to standard thermal-magnetic devices. This unit-mount MCCB is compatible with ABB ReliaGear neXT power panels, SB switchboards, and SACE Tmax XT panelboards. Facility managers can also use it to replace discontinued T4N250EW breakers.Specifications

Product FAQs
8 answersWhich panelboards and switchboards are compatible with the XT4NU3225FY8000XXX?
This XT4 frame breaker is designed for use with ABB ReliaGear neXT Power Panels, ReliaGear SB Switchboards, and SACE Tmax XT Panelboards.
What does the LSI designation indicate on this electronic trip unit?
LSI indicates that the electronic trip unit features adjustable settings for Long-Time (overload), Short-Time (short circuit with intentional delay), and Instantaneous (immediate short circuit) protection. This allows for precise coordination with other breakers in the electrical system.
What are the acceptable wire sizes for the factory-installed lugs on this breaker?
The included lugs accept wire sizes ranging from 4 AWG to 300 kcmil. They are rated for both copper (Cu) and aluminum (Al) conductors.
Is the XT4NU3225FY8000XXX a plug-in or unit mount breaker?
This is a unit mount circuit breaker. It is designed to be bolted directly to the backpan or mounting surface of the enclosure or panelboard, rather than plugging onto a busbar.
Can this ABB XT4 breaker be utilized in direct current (DC) systems?
Yes, this breaker is rated for DC applications. It provides a 35kA interrupting capacity at both 250VDC and 600VDC.
Why choose an electronic trip unit over a thermal-magnetic trip for this 225A breaker?
Electronic trip units provide greater accuracy, repeatability, and adjustability compared to thermal-magnetic units. The adjustable LSI settings on this model allow panel builders to fine-tune the protection curve to match specific load requirements and improve system coordination.
How does the ABB and General Electric parent brand designation affect compatibility?
Following ABB's acquisition of GE Industrial Solutions, the SACE Tmax XT line, including this XT4 breaker, was integrated into the ReliaGear ecosystem. It is designed for modern ReliaGear neXT and SB switchboards, which serve as the current generation of GE and ABB power distribution panels.
Does this breaker belong to the ABB Tmax XT series?
Yes, it is part of the SACE Tmax XT family, specifically utilizing the XT4 frame size. It serves as a direct replacement or new installation component for systems requiring an XT4 electronic trip breaker.
