## H 50 - Maximum DC1 breaking capacity 

- DC voltage (V) 

- • 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.
