Electrical contactor with coil comprising two sets of turns - has electromagnet forming moving and fixed magnetic circuit and rectifier bridge connected to turns in series with switch across one set

摘要

The contactor includes a base (1) which is fixed to the arc casing (2) enclosing a number of moving (13) and fixed contacts. An insulating frame (8) supports the two sets of turns (93,96), a switch to reduce power consumption and the bridge rectifier (85). The fixed contacts of the switch form two lugs to which the outer turns (96) and one end of the inner turns (93) and one end of the bridge are connected. Wires from the inner and outer turns pass over the upper surface of the frame and passes along a groove before passing again over the upper surface of the frame to connect between one of the contacts and the bridge. The wire from the inner turns additionally winds around a mandrel (82).
