摘要： PROBLEM TO BE SOLVED: To provide a vacuum bulb which raises cutoff performance by magnetically driving an arc powerfully immediately after generating of the arc, wherever the arc occurs on an electrode contact surface. SOLUTION: An arm section comprising two or more arms prolonged in a windmill shape form from a central part, and a contact section which is contacted with each arm section in the shape of a windmill at a circumferential section and made of two or more contact blades having a contact surface which contacts a counter electrode during closing of a poke, are formed in integration of the same material. The radial direction component Br of a magnetic flux density which is generated by the current which flows into the arc through the arm section from the central part of one electrode side, and produces a driving force of a rotation direction to the range of 1 mm from the contact surface of its electrode to the arc foot, is made to have more than 6.5 mTesla corresponding to 1 kA of current and ϕ6 of arc diameter when the arc exists near a boundary with the arm on the above contact surface.
