EntelliGuard Selectivity Above GE Current Limiting Circuit Breakers Selectivity between any line side (main)Circuit Breaker with a GE EntelliGuard TU trip unit and a load side (branch) GE current limiting circuit breaker, and certain lighting panel type circuit breakers is determined based on the setting of the line side EntelliGuard TU Trip.
In PB2 & WavePro CB maximum instantaneous multiplier is limited by frame rating. In Entelliguard G the maximum Instantaneous X may be limited by circuit breaker withstand or short time rating (also known as Icw).
Maximum instantaneous is a multiple of rating plug. The above values may be lower if a smaller rating plug than maximum for frame is used. In PB II & WavePro circuit breakers, the maximum instantaneous multiplier is limited by frame rating. In EntelliGuard G, the maximum Instantaneous X may be limited by circuit breaker withstand or short time rating (also known as Icw).
