•
When switching a resistive load (DC1) having voltage and current
values under the curve, an electrical life of
≥
100·10
3
cycles (45.71) and
≥
30·10
3
cycles (45.31, 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.
