Description
Rated 65kAIC at 480VAC, this 3-pole, 200A molded case circuit breaker is engineered for modern power distribution. The ABB XT4HU3200AYJ000XXX utilizes a fixed thermal and fixed magnetic (TMF) trip unit to deliver consistent, current-limiting protection. This plug-on MCCB is specifically designed to mount into ABB ReliaGear neXT panelboards. When paired with the appropriate panelboard, it acts as a seamless substitute for discontinued Spectra RMS SF250 breakers. Load side lugs are included.Specifications

Product FAQs
8 answersWhich ABB panelboards are compatible with the XT4HU3200AYJ000XXX?
This breaker is specifically engineered for ABB ReliaGear neXT power panelboards. It features a unique spring-loaded plug-on connection that attaches directly to the modular bus stack, eliminating traditional bolt-on hardware while providing a highly secure mechanical and electrical connection.
Can I install this 200A XT4 breaker on a standard DIN rail or bare backpan?
No. Because it utilizes the proprietary ReliaGear neXT plug-on mounting style, it cannot be mounted onto standard 35mm DIN rails or traditional bolt-on panelboard backpans. It must be used with a compatible ReliaGear vertical bus assembly.
What type of wiring is compatible with the standard terminal lugs?
The factory-installed lugs are dual rated for both copper (Cu) and aluminum (Al) conductors. They accept wire sizes from 4 AWG up to 300 kcmil, providing flexibility for various feeder sizes depending on your specific load calculations.
Does the XT4HU3200AYJ000XXX require electronic programming for its trip settings?
No. It utilizes a fixed thermal-magnetic trip unit. The Long-Time (overload) and Instantaneous (short-circuit) protection parameters are factory set for standard 200A operation, making installation straightforward without the need for a trip programmer or digital dip switches.
Does this breaker offer sufficient interrupting capacity for commercial service entrances?
Yes. With an interrupting capacity of 65kA at 480VAC and up to 150kA at 240VAC, this breaker is well suited for commercial and industrial facilities with high available fault currents. It safely clears severe short circuits to protect downstream panels and equipment.
Is this molded case circuit breaker strictly for AC voltages?
No, it is fully rated for both alternating current (AC) and direct current (DC) applications. For DC systems, it provides a 50kA interrupting rating at 250VDC and a 65kA rating at 600VDC.
Are the overload and short-circuit protection settings adjustable on this model?
No. The thermal-magnetic trip unit is completely fixed. If your panel design requires field-adjustable trip curves or selective coordination, you will need to specify a Tmax XT4 breaker equipped with an Ekip electronic trip unit instead.
Does the ReliaGear neXT plug-on design restrict whether the panel is top or bottom fed?
No. The modular ReliaGear neXT bus stack and plug-on breaker design is highly flexible. The system can be configured in the field to accommodate either top or bottom feed arrangements without requiring specialized replacement parts.
