- Performance Curves
- A.C. Load Curve 1
- Electrical durability of contacts on resistive loading millions of operating cycles
- 4 / 6
- X Current broken in A
- Y Millions of operating cycles
- A.C. Load Curve 2
- Reduction factor k for inductive loads (applies to values taken from durability curve 1).
- X Power factor on breaking (cos ϕ)
- Y Reduction 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
