PMM 1221-M3 magnetic ship reversible water-proof starter with a casing and built-in fuses, designed for control and overload protection of marine asynchronous three-phase electric motors with a squirrel-cage rotor operating in alternating current networks with a frequency of 50 Hz at a voltage of up to 380V. Starters PMM 1221-M3 are reversible, water-resistant design with a casing and fuses, start, stop and change, if necessary, the direction of rotation of marine electric motors and provide their thermal protection against unacceptable overloads, emergency modes, short-circuit currents and zero protection. Built-in fuses provide instant disconnection of the protected electric motor (in accordance with the time-current characteristic) in the event of an emergency mode accompanied by a short-circuit current. The environment must be non-explosive, free of conductive and abrasive dust, corrosive gases and vapors in concentrations that destroy metals and insulation. The starters are mechanically strong and resistant to both single shocks and sinusoidal vibrations. The starters are designed for operation in the following modes: continuous, intermittent-continuous, short-term and intermittent-frequency with a frequency of up to 600 starts per hour at 40% duty cycle
