• When switching a resistive load (DC1) having voltage and current
values under the curve, an electrical life of ≥100·103 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.
