ABSTRACT:
A three-arm mechanical interlock for a vacuum contactor having one or more vacuum interrupters. The first two arms of the interlock multiply the angular rotation of a shaft connected to the moveable contacts of the interrupters. Shaft travel of about 4 degrees is increased to about 12 degrees at the end of the second arm of the interlock allowing the interlock pieces to be pressed rather than being machined. After the contactor has been opened, the third arm of the interlock transfers position to block the path of the other arms preventing the accidental closing of the contactor. The contactor may not be reclosed until the third arm is transferred back to its original position. Flat surfaces, preferably parallel, can be provided on the shaft and the bore of the first arm attached thereto to provide a self-aligning connection. An extension member can be fastened to the second arm to provide an additional interlock to another device.
