ABB 2CDS781001R3502 S751-E50 Main RCCB 1-pin

The selective main circuit breakers of the series S750 are certified as voltage-independent selective main circuit breakers (SHU) according to DIN VDE 0641-21 as well as have an amateur and designed for the highest over-voltage category. Their range of applications is varied: As a separator at the meter location according to the TAB of the network operators or VDE-AR-N 4101 just like in all low-voltage main distributions for protection of distribution circuits and as activation device with isolating function. The special selectivity properties to ensure high plant availability are to be highlighted. The S750 series is designed for direct mounting on a 4-pole or 5-pole 40 mm (12mm x 5/10mm) busbar system. Regardless of the rated current of the S750, the lower terminal can be fed directly to the busbar system with up to 50mm² and a maximum of 63A. Devices in the S 750 family include an integrated blocking option which enables a simultaneous blocking of the 3 poles of a three-phase power supply. The integrated locking slide locks in THE ON or OFF position and can also be secured with padlock, wire seal or cable tie.
