Box Cover Units

For Plug Fuses

Plug fuse box cover units provide a simple, inexpensive way

to protect small motors with Edison-type “T”, “TL”, “TC”, “P”

and “W” plug fuses. Box cover units are easily installed in

standard electrical boxes. By using fuses sized at the amp

rating of a motor or slightly larger, optimum overload and

short-circuit protection is provided. Box cover units are UL

Listed.
