No, it is equipped with a standard thermal-magnetic LI trip unit. It does not provide ground fault protection.
How is the XT1HU3025AYD000XXX mounted in an electrical enclosure?
It is a unit mount breaker, meaning it secures directly to the chassis or mounting pan with hardware rather than plugging onto a busbar.
How does the interrupting rating change based on system voltage?
The breaker provides 65kAIC for 480VAC systems, but the interrupting capacity increases to 100kAIC when installed on 240VAC systems.
