S751DR-E63

The selective main circuit breakers of the S750DR series are certified according to DIN VDE 0641-21 as voltage-independent selective main circuit breakers (SHU), are suitable for operation by laypersons and are designed for the highest overvoltage category. Their field of application is diverse: as an isolating device at the meter location in accordance with the TAB of the network operators or VDE-AR-N 4101, as well as in all low-voltage main distribution boards for the protection of distribution circuits and as a disconnecting device with isolating function. Particularly noteworthy are the special selectivity properties ensuring high system availability. They are intended for mounting on a 35 mm DIN rail according to DIN EN 60715. Devices of the S 750DR family include an integrated locking facility that allows simultaneous blocking of the 3 poles of a three-phase supply. The integrated locking slide locks in the ON or OFF position and can additionally be secured with a padlock, wire seal or cable tie. The switching state can be monitored via an add-on auxiliary switch.
