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 10 operating cycles x 0.6 = 900 000 operating cycles.
