Air contactors (contactors, which contacts operating in air at normal pressure) are designed for frequent switching electrical circuits, especially three-phase asynchronous motors.
The „V..F“-line contactors are structurally based on „V..E“ and „V..EO“ lines. The „V..F“-line consists of types V85F, V105F, V140F, V170F, V205F and V250F. Contactors contain four auxiliary contacts 2a/2b (2NO/2NC).
