Contactors for Capacitor Switching Switching of power factor correction capacitors WEG’s special CWMC contactors line for capacitor switching is designed according to IEC 60947-1 and UL, and provides the best solution for the switching of your power factor correction capacitors.
Contactors for Capacitor Switching(UA 16 to UA 110) Maximum permissible peak current Î< 100 times the nominal rms current of the switched capacitor. A... and AF... Standard Contactors(A 12 to A 300 and AF 50 to AF 750) Maximum permissible peak current Î < 30 times the nominal rms current of the switched capacitor. Contactors for Capacitor Switching
Application The A...and AF...contactors are suited for capacitor bank switching for the peak current and power values in the table below. The capacitors must be discharged (maximum residual voltage at terminals < 50 V)before being re-energized when the contactors are making.
If the control circuit is connected directly to the same line wires as the load than it must be rated for the same voltage. A capacitor switching contactor uses dampening diodes across each pole designed to minimize the effects of the large charging current. The resistance reading of an open contactor coil would be zero.
WEG’s special CWMC contactors series for switching of capacitors is designed according to IEC 60947-1 and UL, and provides the best solution for the switching of power factor correction capacitors. When capacitor banks are switched, the voltage associated with a low line impedance may produce high currents on the capacitors.
When capacitor banks are switched, the voltage associated with a low line impedance may produce high currents on the capacitors. This current may reach 100 x In, being one of the main causes of reduction in the capacitor useful life. The CWMC contactors feature pre-charge resistors that limit the "in-rush current" when the capacitors are switched.
