• When switching a resistive load (DC1) having voltage and current

values under the curve, an electrical life of ≥ 100·103cycles (45.71) and
≥ 30·10

cycles (45.91) 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.
