MCCB with electronic trip — 3-pole, 60 A, Ekip LSI
The ABB XT2NU3060FAA000XXX is a 3-pole molded case circuit breaker from the XT2N 125 frame, fitted with an Ekip LSI electronic trip unit rated at 60 A. The LSI designation means the trip unit provides long-time (L), short-time (S), and instantaneous (I) protection — adjustable curves that let you coordinate selectively downstream without sacrificing fault clearing speed. This is the variant with UL and CSA approvals, so it lands in North American panels as readily as IEC installations.
Three poles on a 125 A frame with a 60 A trip plug — the frame gives you headroom for coordination; the trip plug sets the continuous current limit. The Ekip LSI electronic trip allows field-adjustable long-time pickup and delay, short-time pickup and delay, and instantaneous pickup. That adjustability is what lets a panel builder tune selectivity with a downstream feeder breaker without swapping hardware. The UL/CSA marking means the breaker carries third-party certification for North American panelboards — an authority signal that saves a submittal resubmission.
