Product Details

Contactor Relays - 3RH1 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

Note

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).

Standards

IEC 60947-1, EN 60947-1, IEC 60947-4-1, EN 60947-4-1, IEC 60947-5-1, EN 60947-5-1.
