多極回路しや断器。 It has an opening/closing mechanism pole with an opening/closing mechanism and a pole without an opening/closing mechanism, and is designed to perform current limiting by separating the movable element by electromagnetic repulsion due to the application of a large current, regardless of the cutting action of the automatic tripping device. In the multi-pole circuit and disconnector, the separation distance of the movable element during electromagnetic repulsion is made larger on the pole side without the opening/closing mechanism than on the pole side of the switching mechanism. Or disconnection.
