3TF3/3RT16 capacitor contactors are used to switch power capacitors that are utilized for reactive current compensation. Special series resistors and auxiliary contacts, integrated in the capacitor contactor, reduce the high inrush current of the capacitor which would otherwise flow. This reduced inrush current guarantees a high contactor and capacitor enhanced life . These contactors are available in sizes S00, S0 and S3 and can generally be equipped with the standard accessories of the basic devices.
• Minimize the effects of in-rust currents during switching
• Suitable for individual as well as bank of capacitors
• Require less space compared to normal contactors
• Ease of maintenance with replaceable resistances and contacts
