る多極形回路しゃ断器。A link holder is attached to the neutral pole part of the rotating shaft that rotates when the main pole is circuited and closed, and the movable contact of the neutral pole is interlocked via a link mechanism connected to the link holder. In this multi-polar circuit breaker, the L link member connected to the link holder and the second link member are connected to the link holder. The link mechanism includes an S-link member having a sliding pin and connected to the link member through a first sliding pin, and connected to the movable contact through a connecting pin, and further comprising: A side wall having a first guide groove and a second guide groove is fixed to the polarity, the first sliding pin is slidably fitted into the first guide groove, and the second guide groove is fitted into the second guide groove. A sliding pin is slidably fitted to restrict the movement of the link mechanism in relation to the shapes and relative positions of the first guide groove and the second guide thought, and the connecting pin is fitted with a torsion pin. A multipolar circuit breaker characterized in that the contact spring is a coil spring, and the contact pressure is applied by the torsion coil spring.
