Switching times
The switching times listed here are guide values which apply to DC switching with rated air gap s
LN
, warm
coil and standard characteristic torque. The switching times given are mean values and subject to vari-
ations. The engagement time t
1
is approximately 8 to 10 times longer for AC switching. ...
