Description
Three-phase output reactor 250A, 380V, 110 kW, 0.028 mH OCL-0250-028U-0.4SA is installed at the output of the frequency converter to filter the current supplied to the 380V three-phase electric motors. The purpose of the output reactor is as follows:
- Creation of inductive resistance to limit the motor power current, thus preventing overload and damage;
- Prevention of sharp current surges during motor starting, which may damage equipment;
- Cleaning the current sine wave from unwanted high harmonics (high-frequency noises) arising in the drive.
Use an AC output reactor in the circuit between the converter and asynchronous motor to improve power quality and ensure safe and long-term operation of the equipment.

Operating conditions of the output reactor (line reactor) OCL-0250-028U-0.4SA
- In the temperature range from minus 10 to 45℃ the nominal parameters of the reactor are tabular. Above 55℃, the nominal current decreases by approximately 2% with each additional +1℃.
- Altitude above sea level should not exceed 2000 m.
- Humidity is less than 90%.
- Environment: free from harmful gases, flammable items, with good ventilation.
When placing the reactor in a cabinet, ensure ventilation for adequate cooling of the equipment.
