Description
Built for rapid installation, this 3-pole 100A plug-on circuit breaker offers advanced LI protection for demanding commercial environments. It utilizes an adjustable thermal-magnetic trip unit to accommodate specific load requirements while maintaining a 100kAIC rating at 480VAC. The breaker mounts into ABB ReliaGear neXT panelboards, serving as a modern substitute for legacy T4L100 and Spectra RMS SE150 devices. Load side lugs are included to streamline the wiring process during setup.Specifications

Product FAQs
7 answersWhat panelboards are compatible with this XT4 breaker?
This breaker is designed specifically for ABB ReliaGear neXT panelboards. It features a plug-on mounting style that connects directly to the ReliaGear neXT bus system.
How does the plug-on mounting work for ReliaGear neXT panelboards?
The ReliaGear neXT system uses a spring-loaded plug-in design instead of traditional bolt-on connections. This allows the breaker to snap securely onto the bus stack, reducing installation time and eliminating the need to torque bus connections.
What does the L in the XT4L frame designation mean?
The L indicates an Extra High interrupting capacity. For this 100A breaker, it provides a maximum interrupting rating of 200kA at 240VAC and 100kA at 480VAC.
Are the thermal and magnetic trip settings adjustable on this breaker?
Yes, this breaker features a Thermal Magnetic trip unit with both adjustable thermal and adjustable magnetic settings. This allows you to fine-tune the overload and short-circuit protection to coordinate with your specific system requirements.
Can this breaker be used in DC electrical systems?
Yes, this XT4 breaker is rated for DC applications. It provides an interrupting capacity of 85kA at 250VDC and 75kA at 600VDC.
What wire sizes are accepted by the lugs on this 100A breaker?
The factory-installed lugs accept wire sizes from 4 AWG up to 300 kcmil. They are rated for use with both copper and aluminum conductors.
What does the LI trip function code indicate on this breaker?
The LI designation means the trip unit provides Long-Time (L) and Instantaneous (I) protection. Long-Time handles overload conditions, while Instantaneous protects against short circuits.
