Fuse holder

A fuse holder for a cartridge type fuse is formed of a housing having a fuse transfer region and a fuse contact region in the interior space thereof. A fuse carrier is provided, which carrier is captured within the housing. The fuse carrier is movable between the fuse transfer region and the fuse contact region. A fuse is inserted or removed into the fuse carrier through a suitable opening provided within the fuse transfer region. Within the fuse contact region there are provided fuse contact members which engage the conductive ends of the fuse when the carrier moves the fuse into the fuse contact region.

Fuse holder

A fuse holder retains and removably connects a fuse to fuse clips within an electrical device. The fuse holder includes a fuse drawer having an open top to hold the fuse. Openings in the fuse drawer are adapted to receive the fuse clips. A guide within the electrical device facilitates sliding the fuse drawer between an open position outside of the electrical device and a closed position within the device. In the closed position, the fuse clips extend through the openings in the fuse drawer and engage the fuse within the fuse drawer to close the electrical circuit within the electrical device. An individual is unable to contact the fuse when the fuse drawer is closed within the electrical device. Similarly, the fuse is disengaged from the fuse clips and the electrical circuit is broken when the fuse drawer is opened so that it is not possible for an individual to contact the fuse while the fuse is connected to the electrical circuit.

Compact fused disconnect switch

A fused disconnect switch assembly includes a pull out fuse assembly and a switch housing assembly. The fuse assembly includes a line side conducting portion, a load side conducting portion, and a fuse element therebetween. The switch housing assembly includes a fuse receptacle for receiving the fuse, a first contact assembly coupled to the line side conducting portion of the fuse and a second contact assembly coupled to the load side conducting portion of the fuse when the fuse is inserted into the receptacle. An open fuse indication device is in communication with conducting portions of the fuse, and an alarm terminal output extends from the switch assembly housing and is in communication with the open fuse indication device. The open fuse indication device provides local fuse state indication and the alarm terminal output facilitates remote fuse state indication when coupled to external circuitry.
