Plug Fuses

W Series

Fast Acting

Voltage Rating: 125V AC

Element is a simple fusible, metal link. For general purpose circuit protection. Quickly opens (blows) when short-circuit or overload occurs. Use for lighting and other non-motor circuits. Edison base.

SL and TL Series

Time-Delay, Loaded Link

Voltage Rating: 125V AC

Heat absorbing metal bead on element link for time-delay. Passes motor overload starting currents without needlessly opening.

Edison base (TL), Rejection base (SL).

S and T Series

Time-Delay, Dual-Element

Voltage Rating: 125V AC

For all-purpose application. Like two fuses in one. A simple link element for short-circuits and dangerous overloads plus a series-connected element which lets the harmless overload starting currents of motors pass without opening. Uses less energy; operates cooler; provides superior protection. Edison base (T), Rejection base (S).

Fustat Fuse Adaptors

Fustat Adaptors (various ampere ratings) screw into the "Edison" Thread fuse sockets of standard household fuse boxes. Adaptors serve the purpose of preventing the wrong size fuse from being used.
