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.
