Siemens 3RH2 Series Contactor, 10 A, 3NO + 1NC, 690 V ac

IEC 60947-1, EN 60947-1, IEC 60947-4-1, EN 60947-4-1, IEC 60947-5-1, EN 60947-5-1. The OFF-delay of the NO contact and the ON-delay of the NC contact are increased if the contactor coils are attenuated against voltage peaks (noise suppression diode 6 to 10 times; diode assemblies 2 to 6 times, varistor +2 to 5 ms). Contactor Relays - 3RH2 Range. Climate-proof, finger safe contactor relays. RC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode) can be plugged onto all contactor relays for damping opening surges in the coil. Size S00 High degree if contact stability at low voltages ; current Suitable for use with solid-state circuits with currents ≥ 1 mA at a voltage of ≥ 17 V Capable of expansion by up to four contacts through use of snap-on auxiliary switch blocks
