Claim:
1. A fuse load-break switch for mounting to a busbar, the fuse load-break switch configured for receiving low-voltage high-power fuses for disconnecting different current phases, the fuse load-break switch comprising: a housing including laterally disposed side walls, each side wall having at least one tub-shaped depression extending along an exterior surface of the side wall; and a fuse contact pair provided within the housing, the fuse contact pair adapted for receiving a fuse for each current phase to be disconnected, wherein the depressions in the side walls are configured to form together with depressions in the side walls of another fuse load-break switch directly adjacently arranged alongside at least one closed heat dissipation duct and at least one closed switching gas dissipation duct, and wherein a thermal power loss brought about by the fuses is dissipated into the at least one heat dissipation duct provided laterally on the housing of the fuse load-break switch.
