Product FAQs
7 answersWhat panelboards are compatible with the XT4HU3100BYJ000XXX circuit breaker?
This plug-on molded case circuit breaker is designed exclusively for use in ABB ReliaGear neXT power panelboards and switchboards.
How does the plug-on mounting system work for this breaker?
The ReliaGear neXT system uses a plug-in design where the line side connector assembly is factory-assembled on the breaker. It snaps directly into the vertical bus stack using a mounting bracket, eliminating the need for bolt-on strap kits and reducing installation time.
What does the H in the XT4H frame designation indicate?
The H indicates a High interrupting capacity tier within the SACE Tmax XT4 family. This model provides a maximum interrupting rating of 65kA at 480VAC and 150kA at 240VAC.
How are the trip settings adjusted on the XT4HU3100BYJ000XXX?
This breaker features a thermal-magnetic trip unit with adjustable dials on the front face. You can independently adjust the thermal setting for long-time overload protection and the magnetic setting for instantaneous short-circuit protection.
Can this ABB Tmax XT breaker replace older GE Spectra RMS breakers?
While the ABB SACE Tmax XT series is the modern replacement for legacy GE Spectra RMS breakers, this specific plug-on model is designed exclusively for ReliaGear neXT panelboards and will not physically fit into older GE Spectra panelboards.
Is the XT4H frame considered a current-limiting circuit breaker?
Yes, the XT4H frame is classified as a UL current-limiting circuit breaker. It is designed to significantly reduce the peak let-through current and energy during a short-circuit event, minimizing thermal and mechanical stress on downstream equipment.
Can the XT4HU3100BYJ000XXX be used in reverse feed applications?
Yes, the XT4 frame supports reverse feed capabilities. Power can be supplied from the bottom terminals up to a maximum of 600V.
