Product type: S751/3DR-K50

S751/3DR-K50 sel. main CB K-Char.,25kA,50A,3x1P

RoHS Compliant

Description

Selective main circuit-breakers of the S 750 DR series are SMCBs based on DIN VDE 0641-21 with voltage-independent operating principle. This means that they do not rely on a control circuit to make or break contact (SHU) and are therefore particularly suitable for use in energy distributionsystems with maximum availability requirements. They offer total selectivity to downstream MCBs and outstanding selectivity to upstream protective devices due to unique current limiting selectivity. S751/3DR-K50
