- Closing delay ms 30 to 100
- Opening delay ms 7 to 13
Arcing time
ms 10 to 15
Switching times at 1.0 x U
s
1)
AC operation
- Closing delay ms 9.5 to 24 9 to 22
- Opening delay ms 4 to 14 4.5 to 15
DC operation
- Closing delay ms 35 to 50
- Opening delay ms 7 to 12
1)
The OFF-delay times of the NO contacts and the ON-delay times of the NC contacts increase if the contactor coils are
attenuated against voltage peaks (suppression diode 6x to 10x; diode combinations 2x to 6x; varistor +2 to 5 ms).
