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 normally closed contact and the on-delay of the normally open contact are increased when the relay coils are protected against voltage spikes (suppression diode 6 to 10 times; diode assemblies 2 to 6 times, varistor +2 to 5 ms). Relay contactors - Series 3RH2. Climate-resistant, touch-safe relay contactors. RC elements, varistors, diodes, or diode assemblies (combination of a diode and a Zener diode) can be connected to all relay contactors to mitigate opening current surges in the coil. Size S00. High contact stability at low voltages and currents. Suitable for semiconductor circuits with currents of ≥1 mA at a voltage of ≥17 V. Expandable by up to four contacts through snap-on auxiliary contact blocks.
