Descriere
Switching capacitors and capacitor banks. Switching devices with high inrush current that require a reduction in inrush current. Contactors KMI-K values ranging from 25 kVAr and above use the power contacts of the composite alloy of cadmium oxide and silver CdOAg85.
These materials are not chemically combined, the smallest grains of cadmium oxide and silver are compressed and form a common composite alloy. Silver provides a low resistance of the contact pair and prevents the formation of an oxide film during operation, which gives a longer service life and low heating of the contacts. Oxide of cadmium interferes with the soldering contacts.
The ratio of 85% silver by weight to 15% cadmium oxide is the best ratio for durable contact operation. Rated control supply voltage Us at AC 50HZ: 230 Rated control supply voltage Us at
