Product FAQs
5 answers
Which electrical panelboards and switchboards are compatible with the XT1SU3030AYD000XXX?
This SACE Tmax XT circuit breaker is engineered for integration with ABB ReliaGear neXT panelboards and ReliaGear SB switchboards.
What is the acceptable wire gauge range for the load side terminals on this breaker?
The factory lug terminals on this unit accommodate conductors ranging from 10 AWG up to 2/0 AWG.
Are the trip unit protection parameters adjustable on this XT1 frame breaker?
No. This model utilizes a TMF (Thermal Magnetic Fixed) trip unit. Both the Long-Time overload and Instantaneous short circuit protection thresholds are factory set and cannot be modified in the field.
Can this 30A circuit breaker be used in direct current systems?
Yes, this breaker is rated for use in DC power systems. It provides a maximum interrupting capacity of 42kA at 250VDC.
How is this SACE Tmax XT molded case breaker mounted?
It is configured as a unit mount breaker, meaning it installs directly to the enclosure or mounting plate using fasteners rather than utilizing a plug-in or drawout assembly.
