The ABB XT5LQ340AEFF000XXX is a 3-pole molded case circuit breaker rated 400 A at 600 VAC, built on the XT5L frame with an EKIP LS/I electronic trip unit. The EKIP LS/I gives you adjustable long-time and short-time pickup and delay, plus instantaneous protection, so you can coordinate selectively downstream without nuisance trips.
The EKIP LS/I trip unit is field-replaceable without removing the breaker from the panel, which saves downtime if you need to change protection curves later.
The continuous current rating is 400 A at 600 VAC, 3-pole configuration.
It uses an ABB EKIP LS/I electronic trip unit with adjustable long-time and short-time protection plus instantaneous trip, housed in a 400 A frame.
