mounted to contactor
1) The opening delay of the NO contact and the closing delay of the
NC contact are increased if the contactor coils are attentuated against
voltage peaks (noise suppression diode 6 to 10 times; diode assemblies
2 to 6 times, varistor +2 to 5 ms).
2) Includes the peak value of the ripple voltage on the DC side.
