20 ABB SACEIntelligent switchgearThanks to the use of electronic releases with dialogue func-tion, the air and moulded-case circuit-breakers mountedinside the switchgear can be controlled and managed by asupervision system.To integrate the moulded-case and air circuit-breakers fit-ted with electronic releases into correct installation man-agement, ABB SACE supplies SD-View 2000, a “ready touse” system consisting of software which, when installedon a personal computer with standard configuration, al-lows full control of the low voltage electrical installation.Modbus ® RTU, the recognised standard in the electricaldistribution sector, is supplied as the communication pro-tocol.ApplicationsSD-View 2000 is a system specially studied for applicationin those electrical distribution installations which requireefficient management without the need to use complex andcostly systems.It is able to dialogue and control all the protection units ofthe installation and, in particular, low voltage Tmax, Isomaxand Emax series of circuit-breakers in the following con-figurations:– Tmax T4 and T5 series of moulded-case circuit-breakers fitted with PR222DS/PD release– Isomax S from S4 to S7 series of moulded-casecircuit-breakers fitted with PR212/P release andPR212/D-M communication unit– Emax E1 to E6 air circuit-breakers fitted withPR112/PD or PR113/PD Modbus releases.VersionsTmax T4 and T5Emax E1…E6Isomax S4…S7
