- Features
| High contact stability at low voltages and currents |
| RC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode) can be plugged onto all 3RH2 contactor relays from the front for damping opening surges in the coil |
| Depending on the version, the solenoid coils of the coupling contactor relays are supplied without overvoltage damping |
| The auxiliary switch block can easily be snapped onto the front of the contactor relays |
