Differential current block 4p 63A 300mA type A Systeme9 400V SE S9V24463 Systeme Electric

Differential current block (DCB) or Vigi-block S9V, Systeme9 series, Systeme Electric, 4-pole, rated current 63 A, leakage current = 300 mA, type A. Complies with the requirements of GOST IEC 61008-1 and GOST IEC 60947-2 standards. Used in electrical networks with a voltage of 400 V. In combination with a circuit breaker, it is designed to protect circuits from overcurrents and people from leakage currents during direct and indirect contact with live parts. Operating principle - electromechanical. Equipped with a mounting busbar for CB, a trip indicator due to leakage current, and protection against errors when selecting the CB. Mounts on a DIN rail using two-position clips.
