Abstract:
A load selector for tapped transformers has an oil tank and a preselector having a first preselector contact and a second preselector contact for each phase to be switched by the load selector. The first preselector contact and the second preselector contact are mounted on a wall of the oil tank and extending through the wall of the oil tank. A first zero contact and a second zero contact separate from the first zero contact are provided for each phase to be switched by the preselector. The first zero contact and the second zero contact are each mounted on the wall of the oil tank and extend through the wall of the oil tank.
