NOTE 1:
Install arc suppressors
across load to avoid module contact
arcing and ensure specified contact life
expectancy.
NOTE 2:
Total operations = operations
(power factor 1) x limitation factor F.
Example:
U = 230 Vac, I = 1 A,
power factor cos
ϕ
= 0,5
Switching power P = U x I = 230 VA
Contact life (cos
ϕ
= 1, P = 230 VA) =
2 000 000 operations (see Figure 1)
Limitation factor F (cos
ϕ
= 0,5) = 0,7
(see Figure 2)
Contact life (cos
ϕ
= 0,5, P = 230 VA) =
F x contact life (cos
ϕ
= , P= 230 VA) =
2 000 000 x 0,7 = 1 400 000 operations.
