Abstract

Fuse load-break switch (1) for low-voltage high-power fuses, a fuse contact pair for receiving a fuse (5A, 5B, 5C) being provided within a housing (2) of the fuse load-break switch (1) for each current phase to be disconnected, characterized in that a thermal power loss brought about by the fuses (5A, 5B, 5C) is dissipated into at least one heat dissipation duct (3) provided laterally on the housing (2) of the fuse load-break switch (1).
