Abstract: Supply rail (1) for supplying current phases (L1, L2, L3) of a low-voltage network to a busbar system or for tapping current phases (L1, L2, L3) from the busbar system, comprising an elongate main body (2) that can be mounted transversely on a plurality of busbars arranged in parallel and includes contact bars (5-1, 5-2, 5-3) that contact the busbars when the supply rail (1) is mounted in order to supply or to tap the current phases (L1, L2, L3) carried on the busbars, wherein each contact bar (5-1, 5-2, 5-3) is directly connected to an associated terminal bus (11-1, 11-2, 11-3), each of which comprises a terminal at an end face of the elongate main body (2) for electrically connecting to the low-voltage network.

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).
