The selective mains circuit breakers of the S750 series are certified in accordance with DIN VDE 0641-21 as a voltage-independent selective mains circuit breaker, as well as being user-friendly and designed for the highest surge category. Their application area is versatile: as a separator at the meter according to the technical connection requirements of the network operators or VDE-AR-N 4101, as well as in all low-voltage main distributors for protection of distribution circuits and as an activation device with separator function. The special selectivity properties ensure high system availability. The S750 series is intended for direct mounting on a 4-pole or 5-pole busbar system of 40 mm (12 mm x 5/10 mm). Regardless of the rated current of the S750, the lower terminal can be used to directly feed into the busbar system, with up to 50 mm² and max 63A. Devices in the S750 family include an integrated locking option that allows simultaneous blocking of the 3 poles of a three-phase supply. The integrated lock slider locks in an on or off position and can also be secured with a padlock, wire seal or cable tie.
