The ABB XT2HU3060JFF000XXX is a molded case circuit breaker from the XT2H 125 frame family, fitted with an EKIP I electronic trip unit set at 60 A, three-pole, with FF (front-flange) terminals, and carries UL/CSA certification.
The XT2H 125 frame supports up to 125 A, so this unit is a lower-rated variant within that frame, allowing coordination with downstream loads while leaving headroom in the frame's interrupting capacity.
