Product FAQs
6 answersWhat panelboards and switchboards are compatible with this XT1 breaker?
This breaker is designed for integration into ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and SACE Tmax XT panelboards.
What does the LI trip function specify on this model?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. On this specific model, both the thermal and magnetic trip thresholds are fixed.
Are the thermal or magnetic trip settings adjustable in the field?
No, this configuration features a fixed thermal and fixed magnetic trip unit. If adjustable trip settings are required for coordination, an XT frame with an electronic trip unit (Ekip) or an adjustable thermal magnetic unit must be specified.
What wire sizes do the factory-installed lugs accommodate?
The standard lugs on this breaker accept wire gauges ranging from 10 AWG up to 2/0 AWG.
Is this breaker suitable for use in DC circuits?
Yes, this thermal magnetic breaker is rated for DC applications up to 250VDC, providing a maximum interrupting capacity of 42kA.
How is this breaker mounted within an enclosure?
This is a unit mount breaker, meaning it is designed to be bolted directly to a backpan or mounting plate rather than plugging into a busbar or utilizing a drawout cradle.
