1)
Total break time = opening delay + arcing time
 AC operation
- Closing delay ms 9 ... 38 8 ... 40
- Opening delay ms 4 ... 16
 DC operation
- Closing delay ms 50 ... 170 50 ... 170
- Opening delay ms 15 ... 17.5
 Arcing time
ms 10
Switching times at 1.0 x U
s
1)
 AC operation
- Closing delay ms 10 ... 18 10 ... 17
- Opening delay ms 4 ... 16
 DC operation
- Closing delay ms 55 ... 80
- Opening delay ms 16 ... 17
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 (varistor + 2 ms to 5 ms, diode combination: 2x to 6x).
