DC voltage (V)
• 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 of the load will be increased.
