Product FAQs
5 answersWhat panelboards and switchboards are compatible with the XT4LU3225BFJ000XXX?
This unit mount breaker is designed for integration into ABB ReliaGear neXT panelboards and ABB ReliaGear SB switchboards. It utilizes the Tmax XT frame architecture for modular power distribution.
Can the Tmax XT4 series replace legacy GE Spectra circuit breakers?
Yes. The ABB Tmax XT4 series serves as the direct replacement for legacy GE Spectra RMS F-frame (SF250) circuit breakers. With the correct ABB retrofit kits, this XT4 breaker can be installed into existing Spectra panelboards to upgrade aging infrastructure.
What wire sizes are accepted by the lugs on this 225A breaker?
The factory-installed lugs accept copper (Cu) or aluminum (Al) conductors ranging from 4 AWG to 300 kcmil. Always verify proper torque specifications in the Tmax XT4 installation manual before terminating the connections.
What protection functions are included in the LI thermal-magnetic trip unit?
The LI designation means the breaker provides adjustable Long-Time (L) overload protection and adjustable Instantaneous (I) short-circuit protection. This allows panel builders to fine-tune the thermal and magnetic trip thresholds to coordinate with downstream devices and specific load requirements.
What does the L in the XT4L frame designation indicate?
The L denotes an extra-high interrupting capacity tier within the ABB Tmax XT4 family. It delivers up to 100kAIC at 480VAC and 200kAIC at 240VAC, making it ideal for heavy commercial and industrial systems with exceptionally high available fault currents.
