Static Contactors

Capasitive Static Contactors

It is used for switching capacitors in compensation systems. Capacitive static contactors switch at the same time as the capacitor voltage and busbar voltage are equalized and prevent high switching currents. In addition, the capacitor switches very quickly without waiting for the discharge time to meet the reactive need of fast loads.

In enterprises where reactive changes are rapid, contactor systems are insufficient to meet the need for compensation. In the compensation of such enterprises, it is possible to respond to rapidly changing loads by switching with thyristor instead of switching with mechanical contactors in classical systems.

In thyristor systems, since the capacitors are activated at zero crossings, there is no need to wait for discharge times. In addition, it is possible to switch on and off at a high speed, since the current drawn when the capacitors are first switched on is minimal.

Inductive Static Contactors

Our new product line, Inductive Static Contactors, is designed to be used for switching three-phase shunt reactors connected to the stages. It is distinguished by its advantages such as silent operation, long life and low failure rates compared to contactors.

*These models can be used with both single-phase and three-phase capacitors. They have 3 thyristors inside as indicated by T3 expression in the product name.

All static contactors have NC (normally closed) thermal control.

Capacitive static contactors must be used in conjunction with a harmonic filter or current limiting reactor.
