Product FAQs
7 answersWhat does the "S" in the XT1S designation indicate for this breaker?
The "S" denotes the Standard interrupting capacity tier for the ABB Tmax XT1 frame. For this 15A breaker, it provides a maximum interrupting rating of 35kA at 480VAC and 65kA at 240VAC.
Can the thermal or magnetic trip settings be adjusted in the field?
No, this breaker features a Fixed Thermal and Fixed Magnetic (TMF) trip unit. Both the long-time overload and instantaneous short circuit protection thresholds are factory set and cannot be modified by the installer.
Which panelboards and switchboards are approved for use with this XT1 breaker?
This unit mount breaker integrates directly into ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and SACE Tmax XT panelboards. It is commonly used when upgrading or expanding these specific distribution systems.
Can this breaker be used to replace legacy GE circuit breakers?
Yes, the ABB Tmax XT series serves as the replacement for several legacy GE lines following ABB acquiring GE Industrial Solutions. Specifically, this XT1SU3015AFD000XXX model can replace legacy T1N015TL breakers.
What temperature rating should be used when sizing conductors for the factory lugs?
Conductors should be sized based on the 75 degrees C ampacity column in the National Electrical Code (NEC). While 90 degrees C insulated wire can be installed, its ampacity must be based on the 75 degrees C rating of the breaker lugs.
What type of protection does the LI trip function provide?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against short circuits.
What is the maximum amperage capacity of the XT1 frame?
While this specific breaker is rated for 15A, the ABB Tmax XT1 frame size can support up to 125A maximum continuous current.
