The 4 pole contactors type 3RT13 and 3RT15 are specially designed to meet specific applications.
These contactors are highly reliable, user friendly and meets the expectation of world class Siemens products. They conform to the latest IEC60947-4-1 standard and carry CE marking.
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.
