Product FAQs
8 answersWhich panelboards and enclosures are compatible with the XT1HU3025AFD000XXX?
This SACE Tmax XT1 breaker is designed for use with ABB ReliaGear neXT Panelboards, ReliaGear SB Switchboards, and standard Tmax XT Enclosures.
What are the acceptable wire sizes and materials for the terminals on this XT1 breaker?
The factory installed lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 10 AWG to 2/0 AWG. Ensure proper torque specifications are followed during installation.
How does the short circuit interrupting rating (AIC) vary by voltage for this 25A breaker?
The interrupting capacity scales based on the system voltage. It provides 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC or 347VAC. It is also rated for 50kA at 250VDC.
Does the XT1HU3025AFD000XXX feature an adjustable trip unit?
No, this specific model features a fixed thermal and fixed magnetic trip unit. If your application requires adjustable pickup settings, you will need to select a different breaker configuration.
How is the XT1HU3025AFD000XXX mounted within a panel or enclosure?
This is a unit mount circuit breaker, meaning it is designed to be bolted directly to the mounting pan, chassis, or backplate rather than plugging into a busbar.
Can this 3 pole ABB breaker be utilized in direct current (DC) systems?
Yes, the XT1HU3025AFD000XXX is rated for DC applications up to 250VDC, providing a 50kA interrupting capacity at that voltage level.
What specific fault protection is provided by the LI trip unit?
The thermal magnetic trip unit provides standard LI protection, which includes Long-Time (thermal) protection against overloads and Instantaneous (magnetic) protection against short circuits.
How does this ABB SACE Tmax XT breaker integrate with GE systems?
Following ABB's acquisition of GE Industrial Solutions, the SACE Tmax XT family is frequently integrated into legacy GE infrastructure, specifically serving as the primary breaker line for ReliaGear panelboards and switchboards.
