3RH2 contactor relays
The following information must be taken into account when planning applications involving
3RH2 contactor relays.
Resistance to extreme climates
3RH2 contactor relays are suitable for use in any climate.
Shock load and vibratory load
The 3RH2 contactor relays have been tested in terms of their shock resistance to sine
pulses and rectangular pulses for AC and DC operation.
Ambient temperature
The 3RH2 contactor relays are dimensioned for operation at ambient temperatures of
between -25 °C and +60 °C. The devices can be stored at temperatures within the range
from -55 °C to +80 °C.
