In installations where load fluctuations are significant and rapid, contactor connection cannot act quickly enough to provide the necessary correction at all times. In such cases, the ideal solution is to apply static contactors based on thyristors to connect/disconnect the capacitors.

CIRCUTOR has developed a series of high performance, compact equipment which includes the static contactor. There are also capacitor modules with static switches built into the header and a whole range of stand alone static contactors that allow banks to be constructed as modules according to requirements.
