Claims

[Claims for Utility Model Registration] A disconnection terminal that has a disconnection section connected to a system bus bar and is provided on a disconnection device such as a circuit breaker by pulling out or pushing the disconnection device using a guide member as a guide; In a closed switchboard that disconnects from or connects to a disconnection section, the disconnection sections connected to a plurality of sets of system buses are arranged alternately for each phase in a line approximately horizontally and in the word width direction, and are opposed to each other. A closure characterized in that the connection state between the disconnection terminal and the disconnection section is changed by arranging the disconnection terminal at a position and moving the pullout device substantially horizontally in the word width direction to pull it out or push it in. switchboard.
