  • Performance Curves

    Performance Curves
    A.C. Load Curve 1

    Electrical durability of contacts on resistive loading millions of operating cycles


    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 durability therefore becomes:1.5 106 operating cycles x 0.6 = 900 000 operating cycles.
