Yes, this breaker is rated for DC applications up to 600VDC, delivering a 35kA interrupting capacity at both 250VDC and 600VDC.
What does the N in the XT4N frame designation signify?
The N denotes the normal interrupting capacity tier for the ABB SACE Tmax XT4 series, corresponding to a 25kA rating at 480VAC.
What does unit mount mean for this XT4 breaker?
As a unit mount breaker, it is designed to be bolted directly to a backpan or mounting plate within an enclosure, rather than plugging or bolting directly onto a panelboard busbar.
