Breaker, Molded Case, 300A, Rating Plug, microEntelliGuard, SG

EntelliGuard TU Trip Units are designed with UL-Listed interchangeable rating plugs. These rating plugs change the per-unit (1X) continuous current rating of the breaker. A circuit breaker frame equipped with a suitable rating plug has a long-time trip value equal to the ampere rating marked on the rating plug. For example, a breaker frame with a 1600 A sensor and an 800 A rating plug has an 800 A continuous current (long-time) rating.
