Residual current switch 4p 100A 300mA type AC-S Systeme9 400V SE S9R19491 Systeme Electric

Residual Current Circuit Breaker (RCCB) or Residual Current Device (RCD) S9R, Systeme9 series, Systeme Electric, 4-pole, rated current 100 A, leakage current = 300 mA, type AC S. Complies with GOST IEC 61008-1 and GOST IEC 60947-2 standards. Applied in electrical networks with voltage 400 V. Designed to protect people from leakage currents during direct (10 and 30 mA) and indirect (100 mA) contact with live parts, as well as to protect electrical installations from fire (300 mA). Operating principle - electromechanical. Neutral on the left. Equipped with double safe terminals for separate conductor mounting, instantaneous switching mechanism, contact group status indicator, and leakage current trip indicator. Mounts on a DIN rail using two-position latches, with the possibility of disassembly without removing the PIN busbar.
