Circuit breaker, fuse fuse for low voltage and high power

摘要

Abstract fuse load break switch (1) for low voltage high power fuses, fuse contact pair for receiving the fuse (5a, 5b, 5C) being provided within the housing (2) of the fuse load break switch (1) for each current phase to be disconnected, characterised in that the thermal power loss brought about by T. And 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).
