The multiple pole modular switch device comprises a first block formed by a base plate (1) comprising first fixing means (11) and a quick break mechanism (not shown) controlled by an operating handle (13) and a second block, secured to the first block by second fixing means (18, 25), formed by a modular assembly of switch cases (2) firmly secured together. Each switch case (2) comprises a first and second means (231) for connecting to an electric supply circuit and means (27) for interrupting the electric circuit at (270, 271) connected by one end to a first one of the connection means (231) said quick break mechanism actuating through interconnected transmission means (17, 223, 224, 221, 222, 220) the interruption means of the different switch case modules (2). On the second block there is fixed a third block comprising a modular fuse holder assembly (3). Operation of the handle (13) effects movement of a fork (17) by means of the bistable quick break mechanism. <IMAGE> |
