Fuse holder

A fuse holder for connecting a fuse, having a pair of knives, to a busbar device, in which the fuse holder is configured for connecting three fuses to a three-phase electrical line, the fuse holder comprising:

• a housing defining;
• for each of the three fuses, a pair of fuse contact openings in a front face of the housing configured to receive the knives of the fuse in a respective one of the contact openings when the corresponding fuse is inserted into the fuse holder;
• and
• a busbar contact opening in a back face of the housing;
• a wire terminal mounted within said housing and accessible for electrical connection with a wire of an external device;
• for each of the three fuses, a line conductor mounted within said housing and including;
• a fuse contact portion aligned with one of the pair of fuse contact openings to contact a knife of the corresponding fuse received through said fuse contact opening, and
• a busbar contact portion extending through said busbar contact opening and configured for electrical connection to the busbar device when the fuse holder is mounted on the busbar device;
• for each of the three fuses, a load conductor mounted within said housing and including;
• a fuse contact portion aligned with the other of the pair of fuse contact openings to contact a knife of the corresponding fuse received through said fuse contact opening, and
• a terminal contact portion in contact with said wire terminal;
• and
• an engagement mechanism for releasably engaging the fuse holder to the busbar device,
• wherein the line conductors for each of the three phases are configured so that the busbar contact portions of the line conductors are vertically separated along a length of said housing for electrical engagement to the busbar device.

• a pair of fuse contact openings in a front face of the housing configured to receive the knives of the fuse in a respective one of the contact openings when the fuse is inserted into the fuse holder;
• a busbar contact opening in a back face of the housing;
• an ejector opening defined in said housing;
• an ejector slidably mounted in the ejector opening to contact the fuse when the fuse is inserted into the fuse holder;
• and
• an ejector spring mounted within the housing to push the ejector through the ejector opening and against the fuse, said spring configured to push the ejector outward relative to the ejector opening against the fuse to dislodge the fuse from the fuse holder;
• a wire terminal mounted within said housing and accessible for electrical connection with a wire of an external device;
• a line conductor mounted within said housing and including;
• a fuse contact portion aligned with one of the pair of fuse contact openings to contact a knife of the fuse received through said fuse contact opening, and
