Abstract
The invention refers to a fuse switch module (1) that comprises a casing (2) having an aperture (3) and a cover (4) for closing and opening the aperture (3), and a rotatable fuse cartridge (11) for receiving a fuse (8). The fuse cartridge (11) is rotatable between a switch module closed position in which a fuse (8) is connected with fixed contacts (5,6) to enable current circulation, and a switch module open position in which current circulation through the fixed contacts (5,6) is impeded. The cover (4) and the fuse cartridge (11) are engaged when the cover (4) is closing the aperture (3) and when the fuse cartridge (11) is in the switch closed position, thus, the cover (4) is locked by the fuse cartridge (11) and opening of the cover (4) is impeded while current is circulating through the switch module.
Claims17
A fuse switch module, comprising:
- an electrically insulating casing having an aperture providing access to a casing interior, and a cover installed at the aperture in movable manner for opening and closing the aperture;
- a pair of fixed contacts inside the casing;
- and
- a rotatable fuse cartridge made of an electrically insulating material inside the casing, wherein the rotatable fuse cartridge is adapted for receiving a fuse, so that when the fuse is received in the rotatable fuse cartridge, the fuse and the rotatable fuse cartridge are jointly rotatable;
- wherein the rotatable fuse cartridge is rotatable between a fuse switch module closed position in which the fuse is connected with the pair of fixed contacts to enable current circulation through the fuse and the pair of fixed contacts when the fuse is received in the rotatable fuse cartridge, and a fuse switch module open position in which the current circulation through the pair of fixed contacts is impeded;
- wherein the cover and the rotatable fuse cartridge are configured to engage with each other, when the cover closes the aperture and when the rotatable fuse cartridge is in the fuse switch module closed position, such that the cover is locked by the rotatable fuse cartridge and opening of the cover is impeded.
A switch assembly, comprising:
- at least two fuse switch modules, each of the at least two fuse switch modules including:
- an electrically insulating casing having an aperture providing access to a casing interior, and a cover installed at the aperture in movable manner for opening and closing the aperture;
- a pair of fixed contacts inside the casing;
- and
- a rotatable fuse cartridge made of an electrically insulating material inside the casing, wherein the rotatable fuse cartridge is adapted for receiving a fuse, so that when the fuse is received in the rotatable fuse cartridge, the fuse and the rotatable fuse cartridge are jointly rotatable;
- wherein the rotatable fuse cartridge is rotatable between a fuse switch module closed position in which the fuse is connected with the pair of fixed contacts to enable current circulation through the fuse and the pair of fixed contacts when the fuse is received in the rotatable fuse cartridge, and a fuse switch module open position in which the current circulation through the pair of fixed contacts is impeded;
- wherein the cover and the rotatable fuse cartridge are configured to engage with each other, when the cover closes the aperture and when the rotatable fuse cartridge is in the fuse switch module closed position, such that the cover is locked by the rotatable fuse cartridge and opening of the cover is impeded;
- wherein the at least two fuse switch modules are assembled about a common operating axis, and wherein the rotatable fuse cartridges of the fuse switch modules are coupled so as to simultaneously rotate, wherein the rotatable fuse cartridges have respective fuses received therein and respective conductive blades coupled respectively with the fuse terminals, and wherein at least one of the fuse switch modules has the two conductive blades arranged so that the long lateral edges of the two conductive blades are closer to the center of the fuse than the short lateral edges, and wherein at least one of the fuse switch modules has the two conductive blades arranged so that the long lateral edges of the two conductive blades are closer to the fuse free opposite ends than the short lateral edges.
