Special contactor for three-phase capacitors
Special contactor for three-phase capacitors - It is a special specification that can be used in power factor correction circuits without a choke. - In group power factor correction circuits, especially those primarily connecting multilayer capacitors, inrush currents can reach up to 180 times the motor rating, but this circuit is also suitable for such applications. - It comes with a series resistor. - The special pre-charging auxiliary contacts and resistor charge the capacitors before the main connection, reducing inrush current. - Some models come with discharge resistors for capacitors. This can prevent polarity reversal that occurs during repeated high-speed connections. Composite discharge time is 0.2 seconds.
