ABSTRACT:
A fused disconnect device constructed according to the present invention comprises a housing, a line side terminal, a load side terminal, a protection fuse holder assembly removably installed in a cavity of said housing, and a separate alarm fuse removably installed in said housing. The alarm fuse may remain installed in the housing regardless of the presence of the protection fuse holder assembly, so that an alarm will be generated whenever the inventive device has interrupted power to the load. In a first embodiment of the invention, the disconnect device is adapted for front-access mounting in a power distribution panel. In a second embodiment of the invention, the disconnect device is adapted for rear-access mounting in a power distribution panel. A third embodiment is adapted for use in higher-current applications.
