Info

To carry out the cabling, a shielded twisted pair cable (notsupplied; ask ABB for information) can be used. The shieldshould only be earthed on the trip unit of the circuit-breaker onthe supply side.The maximum length of the cabling for zone selectivity, betweentwo units, is 300 meters.The maximum number of the circuit-breakers which can be connectedto the outputs (Z out) of a trip unit is 20.All Emax circuit-breakers in versions B-N-S-H-V fitted with PR122and PR123 trip units allow zone selectivity to be realised.NoteWith regard to selectivity in the case ofearth faults with circuit-breakers in series,see page 6/20.Zone 3 Zone 2 Zone 11SDC200186F00016ABB SACE 6/11
