Residual current circuit breaker 4p 100A 300mA type A-S Systeme9 400V SE S9R29491 Systeme Electric

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