F 44 - Electrical life (AC) v contact current
• When switching a resistive load (DC1) having voltage and current
values under the curve, an electrical life of ≥ 100·103can 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.
