I plan to use Schneider MCCB with rotary handle (long shaft version), than use stepper motor to operate MCCB automatically
and use MCCB auxiliary contact to detect open, closed, or tripped position; stepper motor is controlled by PLC
also stepper motor is not position-locked when power off (if not, it can caused damaged to MCCB nor stepper motor, ex. if MCCB is tripped but locked in closed position by stepper motor)
Problem is, how can I find right motor torque for this task ?,
and how can I prevent such scenario when MCCB is going to be closed by stepper motor (after closed or tripped), but it's instantly tripped after closed by stepper motor, do you think there is any way to prevent this ?,
Do you think this is good idea ?
I use EZC250 series with EZEROTE rotary handle and Compact NSXm series with LV426935 rotary handle
There is no official motorized available from Schneider
