Abstract

A safety device for use in connection with a heavy current circuit breaker consists of fuse boxes 17, 19, 21 to be fixed individually on a switch housing 11 and to keep separate a group of contacts 16 with associated knife fuses 23, 25. The fuse boxes are provided with locking pins 41, 43, 45 which by the use of a common operating device 47 can collectively be brought into a locking position for the fuses 23, 25 when the breaker is connected. When the breaker is disconnected the locking pins are released and return to a free position by means of return springs 51, 53, 55, in which position the fuses can be freely removed and inserted in their respective contact parts 16. Each individual box 17, 19, 21 is further designed with internal walls 29, 31, 33 for limiting the freedom of movement of the fuses, whereby the protection against touching is increased. Each fuse box has a cover 60 which also acts as a handle when inserting and removing a fuse. The handle 60 has a lock 71 which interacts with the fuse to prevent the fuse from being released unintentionally and is designed to lock itself when the cover is put on. In this way the cover cannot be removed when the breaker is connected, as the locking pins prevent the removal of the fuses. <IMAGE>
