Selection and ordering data
1)
The OFF-delay of the NO contact and the ON-delay of the NC contact are
increased if the contactor coils are attenuated against voltage peaks
(suppression diode 6x to 10x; diode assembly 2x to 6x;
varistor +2 to 5 ms).
2)
Includes the peak value of the alternating voltage on the DC side.
