RSO ..25
It is recommended to protect the solid state relay against
overheating. Therefore the chart also states the maximum
switching temperature (70, 80 or 90 °C) for the optional
temperature limit switch.
RSO ..90, RSO ..110
Compare the value found in the load current versus tempe-
rature chart with the standard heatsink values and select the
heatsink with the next lower value.
