Description
Three-phase motor choke 60A, 380V, 22 kW, 0.12 mH OCL-0060-0M12-0.4SC is installed at the output of the frequency converter to filter the current supplied to the 380V three-phase electric motors. The function of the output electric choke is as follows:
- Creates inductive resistance that limits the motor supply current, thereby preventing overload and damage;
- Prevents sharp current surges during motor start-up, which can damage equipment;
- Cleans the current sinusoid from unwanted high harmonics (high-frequency noises) occurring in the electric drive.
Use an AC output choke in the circuit between the converter and asynchronous electric motor to improve power supply quality for the drive, as well as safe and long-term operation of the equipment.

Operating conditions of motor choke (line reactor) OCL-0060-0M12-0.4SC
- In the temperature range from minus 10 to 45℃ the nominal parameters of the choke are tabular. At temperatures above 55℃, the nominal current decreases by approximately 2% for each additional +1℃.
- The altitude above sea level should not exceed 2000 m.
- Air humidity less than 90%.
- Environment: free from harmful gases, flammable objects, with good ventilation.
When installing the choke in a cabinet, provide ventilation for sufficient cooling of the equipment.
