DESCRIPTION
Edison-base plug fuses (WOO, TOO, and TLO series) have
threaded metal shells and contacts similar to incandescent
lamp bases. Fuseholders for Edison-base fuses have
matching metal threads similar to standard light sockets.
Type S fuses (SLO and SOO series) have nonmetallic
threaded bases which fit matching nonmetallic threads in
Type S fuseholders.Type S fuseholders are size-limiting, and
will not accept Type S fuses with ampere ratings greater than
the ampere rating marked on the Type S fuseholder.Type S
fuses will not fit Edison-base fuseholders, nor can Edison-
base fuses be used in Type S fuseholders.
Approvals:
UL Listed plug fuses.
Note:
Although rated at 125 volts, NEC permits plug fuses to
be used in circuits not exceeding 150 volts to ground. See
NEC Article 240-E.

SAO Type S Fuse Adapters
inserted into Edison-base
fuseholders permanently convert them to Type S fuseholders.
They accept Type S fuses only.
APPLICATIONS
The National Electric Code now permits Edison-base fuses to
be used only for replacements in existing installations, and
then, only when there is no evidence of overfusing or
tampering. All new Edison-base fuseholders must have Type
S fuse adapters installed before they are placed in service.
Designed to prevent installation of wrong size fuses, Type S
Adapters (SAO series) screw into Edison-base fuseholders so
they may accept Type S fuses. Once installed the adapters
cannot be removed.
To prevent shunting of open fuses or overfusing, and to
reduce nuisance fuse opening, it is recommended that SAO
adapters with properly rated SLO or SOO series fuses be
installed in all Edison-base fuseholders.
TYPE S PLUG FUSES
SOO Fuses
are dual-element time-
delay Type S fuses designed for motor
and motor branch-circuit protection;
also suitable for all general-purpose
circuits.

WOO Fuses
are non-delay Edison-
base fuses, best suited for incandes-
cent lighting, resistance heating, and
general purpose circuits with no
significant motor load. Not recom-
mended for motor circuits. See TOO
and SOO fuses. Use for replacement
purposes only.
