Key
1) Refer to
Dimensions
2) Specifications apply to 50 Hz; at 60 Hz, the running times are about 17% shorter.
3) Approx. 20% torque reduction with undervoltage
4) Under rated conditions, under extreme conditions (e.g., +60°C, 230 V AC -15%) approx. -25%
5) Free auxiliary switches (along with 2 end switches)
6) When looking at the shaft and control voltage at end switch
