Performance CurvesPerformance CurvesA.C. Load Curve 1
Electrical durability of contacts on resistive loading millions of operating cyclesXCurrent broken in AYMillions of operating cyclesA.C. Load Curve 2
Reduction factor k for inductive loads (applies to values taken from durability curve 1).XPower factor on breaking (cos ϕ)YReduction factor k
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 C : Off-Delay Relay with Control SignalDescription
After power-up and closing of the control contact C, the output R closes. When control contact C re-opens, timing T starts. At the end of the timing period, the output(s) R revert(s) to its/their initial state. The second output can be either timed or instantaneous.Function: 1 OutputFunction: 2 Outputs
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)Legend
