That 400 A figure is the continuous current rating — it carries that load indefinitely without tripping, making it a main or large feeder breaker for a 400 A panelboard or switchboard. The 3-pole configuration matches three-phase wye or delta services. ## Trip unit: EKIP DIP LSI IN400 The EKIP DIP LSI trip unit provides adjustable Long-time (L), Short-time (S), and Instantaneous (I) protection curves. The IN400 designation means the trip unit is rated for a 400 A sensor — matched to the breaker frame. The DIP switches on the front face let you adjust the pickup and delay settings without removing the cover. ## Regulatory and compliance documentation ABB provides the standard compliance package: RoHS and REACH declarations, UL file number, and IEC test reports on request. For a panel shop needing to document the SCCR or the interrupting rating, the datasheet and UL certificate are available with the order.","metaTitle":"ABB XT5HU340AFFN000XXX XT5H 400A MCCB, 600VAC, EKIP DIP LSI","metaDescription":"ABB XT5HU340AFFN000XXX molded case circuit breaker, 400A, 600VAC, 3-pole, EKIP DIP LSI trip unit.
