- When switching a resistive load (DC1) having voltage and current values under the curve, an electrical life of ≥ 100 · 10[3] can be expected. - In the case of DC13 loads, the connection of a diode in parallel with the load will permit a similar electrical life as for a DC1 load. Note: the release time for the load will be increased. **==> picture [123 x 76] intentionally omitted <==** **==> picture [120 x 41] intentionally omitted <==** **----- Start of picture text -----**
