ABB 2CDS781001R4252 S751/3-E25 Main RCCB 3-pin

The selective main circuit breakers of the series S750 are certified according to DIN VDE 0641-21 as voltage-independant selective main circuit breakers (SHU) as well as amateur operable and designed for the highest overvoltage category. Their application range is diverse: As a separating device at the counter slot according to the TAB of the network operator or VDE-AR-N 4101 just as in all low-voltage main distributions for the protection of distribution circuits and as an isolating device with separation function. The special selectivity properties are to be emphasized to ensure high plant availability. The S750 series is intended for direct mounting on a 4 or 5-pole 40mm busbar system (12mm x 5/10mm). Independant of the rated current of the S750, the lower terminal can be directly fed to the busbar system with up to 50mm² and max. 63A. Devices of the S 750 family include an integrated blocking option, which enables a simultaneous blocking of the 3 poles of a three-phase supply. The integrated locking slide locks in OR OUT position and can also be secured with padlock, wire seal or cable ties.
