Example: An LC1-F185 contactor supplied with 115 V/50 Hz for a consumption of 55 VA or a current consumption equal to 0.1 A and cos ϕ = 0.3. For 0.1 A, curve 1 indicates a durability of approximately 1.5 million operating cycles. As the load is inductive, it is necessary to apply a reduction coefficient k to this number of cycles as indicated by curve 2. For cos ϕ = 0.3: k = 0.6 The electrical durability therefore becomes:1.5 106 operating cycles x 0.6 = 900 000 operating cycles.D. C.

Technical DescriptionFunction Qc: Star-Delta TimingDescription
On energisation, the star contact closes instantaneously and timing starts.
At the end of the timing period, the star contact opens.
After a 50 ms pause, the delta contact closes ans remains in this position.Function: 1 OutputLegend
