DC voltage (V)
DC breajking current (A)
• 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.
