Neozed Fuses are more compact than
the Diazed Fuses. Three sizes are
available, D01 to 16 Amps, D02 to 63
Amps and D03 to 100 Amps. Fuse
accessories are sized to match. Each
size fuse body has a different diameter
to fit only into the appropriate Screw
Cap and Fuse Base. (See illustration pg

10.)
Also, the fuse tips have different

diameters, depending on their current
rating. The diameter of the tip matches
the diameter of the hole in the Adapter
Ring to insure that no fuse with a higher
rating than intended for the circuit can
be installed. This prevents damage to
the circuit or equipment the fuse
protects. Additionally, fuses and Adapter
Rings are color coded to avoid
mismatching; for example: 10 Amp
Neozed fuses have red pop-out
indicators on their head, matching the
red 10 Amp Adapter Ring.

When a Neozed fuse has blown, the
color coded indicator on the head of the
fuse will pop out, giving visible indication
through a glass window in the Screw
Cap.

The Fuse is held in place by the Screw
Cap, which is screwed into the Fuse
Base. Neozed Fuse Bases are available
in one and three pole designs. Fuse
Bases can be panel mounted or
snapped onto a standard 35mm DIN
rail.

ACCESSORIES

SCREW CAP

The Screw Cap types offered fit the
various fuse and Fuse Base sizes. They
hold the fuses in place and connect the
head of the fuse with the load side of the
Fuse Holder. The colored blown fuse
indicator on the head of the fuse is
clearly visible through a small window in
the top of the Screw Cap. A small test
hole on the side of the Cap allows for a
probe to test if voltage is present on the
metallic surface on the head of the fuse.

ADAPTER SCREW / RING

Adapter Screws are used with the
Diazed, and Adapter Rings are used with
the Neozed Fuses. Three sizes of
Screws and Rings are available to fit the
diameter of the different size fuse bases.
Adapter Screws are porcelain rings with a
center hole on one side, a threaded stud
on the other and one notch on each side.
The inside diameter of the center hole of
the Adapter Screw matches the diameter
of the tip of the Diazed fuse for which it is
intended. This helps to eliminate the
insertion of fuses with higher current
ratings than allowed. The integral
threaded stud installs into the appropriate
Diazed Fuse Base. Adapter Screws and
Rings are color coded to the fuses.

FUSE BASE

Fuse Bases hold fuses in place (in
conjunction with the Screw Cap) and
insure proper electrical connections.
They snap easily onto standard 35mm
DIN rail or can be panel mounted. They
are available in one or three pole
designs. Matching Covers are available.
The line is connected to the metal tab at
the bottom of the fuse base. The load is
connected to the metal ring into which
the Screw Cap is installed.

Fuse Base Covers are available in one

Bases we offer. They help prevent shock
from accidental touching of conducting
metal parts on the Base.

TOOLS

The Adapter Screw / Ring Tools aid in
the insertion and removal of the Adapters
from the Fuse Base. The Adapter Screw
Tool fits into notches on the Adapter
Screw for the D27 and D33 Diazed
fuses. The Adapter Ring Tool fits the
Adapter Rings for the D01, D02 and D03
Neozed fuses. We strongly recommend
these tools be used when inserting or
removing Adapter Screws or Rings to
prevent electrical shocks.
