M: Motor The motor automatically recharges the closing springs of the circuit-breaker when these are discharged.
The motor is equipped with a limit contact S33 M/1 that interrupts the power supply of the motor after
charging of the springs is completed.
The motor is equipped with a limit contact S33 M/2 that signals the state of the charged springs.For information
on the S33 M/2 limit contact refer to the dedicated paragraph "S33 M/2: springs charged signalling contact"
in this chapter.
