ABSTRACT:
The present invention relates to a fuse-relay including a first pole (1, 11, 21, 31, 81) and a second pole (2, 12, 22, 32, 82). According to the invention the fuse-relay includes a resilient device (5, 18, 27, 37, 87) that is held in an elastically deformed position by a fuse (6, 16, 26, 36, 86) when the fuse (6, 16, 26, 36, 86) is whole; and in that the resilient device (5, 18, 27, 37, 87) is arranged to make or break a connection between the first pole (1, 11, 21, 31, 81) and the second pole (2, 12, 22, 32, 82) when the fuse (6, 16, 26, 36, 86) is blown. The invention also relates to a cross-connect with such fuse-relays, to a telecommunication system with such cross-connects and to a connection method.
