- When switching a resistive load (DC1) having voltage and current values under the curve, an electrical life of ≥ 100 · 10[3] for 43.41 and ≥ 50 · 10[3 ] for 43.61 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.
