Product details

MCCB with EKIP LSI trip — 150 A, 3-pole, UL/CSA

The ABB XT4HU3150FFJ000XXX is a XT4H 250 frame molded case circuit breaker fitted with an EKIP LSI electronic trip unit, rated at 150 A, 3-pole, with F-F (front-front) terminals. The UL/CSA listing means it is accepted for panelboard and switchboard installations in North American markets. The EKIP LSI trip provides adjustable long-time (L), short-time (S), and instantaneous (I) protection curves, letting you coordinate selectively downstream without sacrificing fault clearing speed.

The XT4H frame mounts in a fixed or plug-in base within a switchboard or panelboard enclosure. The F-F terminals accept bus-bar or cable connections from either direction, simplifying bus-stack layout. The EKIP LSI trip unit draws its power from the line-side current transformers, so no auxiliary control power is needed for the protection functions.
