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.","metaTitle":"ABB XT5LQ340AEFF000XXX Molded Case Breaker, 400A 600VAC 3P","metaDescription":"ABB XT5LQ340AEFF000XXX molded case circuit breaker, 400 A, 600 VAC, 3-pole, XT5L frame with EKIP LS/I trip unit.
