Actuators are electromagnetic

Actuators electromagnetic PML are intended for remote start - up by direct connection to a network, stops and reversals of three - phase asynchronous electric motors with a short - circuited rotor at a voltage of alternating current up to 660B with a frequency of 50 Hz, and performed by with triple - pole thermal relays of the RTL series (TU 16 - 523. 54982) for protection of the operated electric motors against overloads of inadmissible duration and against the currents arising at break of one of phases.

Actuators can be completed with limiters of retension like OPN. The actuators completed by overstrain limiters are suitable for work in control systems with use of microprocessor equipment.
