Residual current circuit breaker 3p 63A 300mA type AC Systeme9 400V SE S9V14363 Systeme Electric

Differential current block (BDT) or Vigi-block S9V, Systeme9 series, Systeme Electric, 3-pole, rated current 63 A, leakage current = 300 mA, type AC. Complies with GOST IEC 61008-1 and GOST IEC 60947-2 standards. Applied in electrical networks with voltage 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 circuit breakers, a trip indicator due to leakage current, and protection against errors when selecting a circuit breaker. Mounts on a DIN rail using two-position latches.
