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