A versatile solution for industrial environments, the ABB XT1SU3100AFD000XXX is a 3-pole, 100A molded case circuit breaker. It utilizes fixed thermal and magnetic trip elements to deliver precise long-time and instantaneous (LI) overcurrent protection. Designed for broad compatibility, this unit mount breaker fits ABB ReliaGear neXT panelboards, SB switchboards, and SACE Tmax XT panels. It also replaces the legacy T1N100TL.

Product FAQs
7 answers
Which panelboards are compatible with the XT1SU3100AFD000XXX?
This XT1 frame breaker is designed for installation in ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and SACE Tmax XT panelboards.
What wire sizes and materials do the factory lugs accept?
The standard lugs on this breaker accommodate conductor sizes from 10 AWG up to 2/0 AWG. They are dual-rated for both copper (Cu) and aluminum (Al) wire.
Are the thermal and magnetic trip settings adjustable on this model?
No. This specific model features a thermal-magnetic trip unit with fixed thermal (Long-Time) and fixed magnetic (Instantaneous) settings, meaning neither the overload nor the short-circuit pickup can be adjusted in the field.
Is this breaker suitable for direct current (DC) systems?
Yes, it carries a DC rating of up to 250VDC with a 42kA interrupting capacity, allowing it to be used in compatible direct current control or distribution circuits.
Does this breaker plug into the busbar or bolt on?
The XT1SU3100AFD000XXX is a unit-mount breaker. It must be bolted directly to the mounting plate or chassis and wired to the bus, rather than plugging directly onto the busbars.
What type of fault protection does the LI trip unit provide?
The LI trip function provides fundamental thermal-magnetic protection. The Long-Time (L) function protects the circuit against sustained overloads, while the Instantaneous (I) function trips the breaker immediately during a short circuit.
Why is this breaker associated with both ABB and General Electric?
ABB acquired GE Industrial Solutions and integrated their product lines. The SACE Tmax XT family, including this XT1 frame, serves as the modern replacement for legacy GE molded case circuit breakers in newer ReliaGear panelboards.
