Electrical Durability and Load Limit Curves
AC Load
Curve 1: Electrical durability of contacts on resistive load in millions of operating cycles
X
Y
Current broken in A
Millions of operating cycles
Curve 2: Reduction factor k for inductive loads (applies to values taken from durability Curve 1)
X
Y
Power factor on breaking (cos φ)
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 0.5 A and cos φ =
0.3.
For 0.5 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 x 10 operating cycles x 0.6 = 900 000 operating cycles
