magnetic starters PMA-3 4212B and PME-222U3I

The electromagnetic starter (magnetic starter) - PMA 4212B is a low-voltage electromagnetic (electromechanical) combined distribution and control device designed to start and accelerate the electric motor to the rated speed, ensure its continuous operation, turn off the power and protect the electric motor and connected circuits from operating overloads. The starter is a contactor equipped with additional equipment: a thermal relay, an additional contact group or an automatic motor starter, and fuses. In addition to simple switching on, in the case of controlling an electric motor, the starter can perform the function of switching the direction of rotation of its rotor (the so-called reversing circuit), by changing the order of the phases, for which a second contactor is built into the starter. Three-phase motor windings are switched from star to delta to reduce the starting current of the motor.
