Features and Benefits
• Time-delay, dual-element T Series Edison base plug fuses
provide small motor overload protection when used with
box cover units.
• Time-delay, dual-element S Series plug fuses provide a
rejection feature (when used alone or with Fustat adapters
to retrofit Edison base holders) to prevent overfusing of
branch circuits.
Specifications
Description: Adapters for using Type S and SL rejection
fuses in Edison base fuse sockets.
Features and Benefits

of standard fuse boxes making it easy to retrofit existing
fuse installations
• Available in various amp ratings to cover a wide range of
rating requirements
Typical Applications
• Plug fuse installations where it is desirable to restrict fuse
amp ratings
