Three-phase dv/dt limiting reactor ED3du
Limiting reactors are basic elements for motor protection. Insulation system of the motor is protected against high steepness of PWM voltage pulses generated by a frequency converter. ED3du reactors are the most effective with short to medium length of motor cables. They are the minimum necessary that the user should provide for the purpose of long, failure-free operation of the AC motor.
