A switching contactor connects or disconnects capacitor banks to the electrical network to manage reactive power compensation, improving power factor and system efficiency.
Typical rated operational voltage is 230–690 V AC, and rated operational current is 16–125 A, per IEC 60947-4-1. Actual values depend on the specific model.
An electromagnetic coil, when energized, creates a magnetic field that closes contacts, connecting the capacitor bank. When de-energized, springs open the contacts, disconnecting the bank.
Relevant standards include IEC 60947-4-1 for contactors, IEC 60831-1 for capacitor ratings, and IEC 60947-1 for general requirements. Always verify compliance with the manufacturer.
