DIAZED AND NEOZED
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 COVER
Fuse Base Covers are available in one
and three pole designs to match the Fuse
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.

The main characteristics of
fuse disconnectors are:
•UL recognized (10x38mm)
•UL listed (CC Type)
•Compliance with IEC
60947-1, IEC 60947-3
•Plastic parts are made of
material resistant to high
temperatures
•All contact surfaces are
silver plated
•Mounting on standard DIN
35 mm rail (DIN EN60715).
•Available up to 4 pole
•For all sizes a version with
electronic indicator is
available. There are two
technical types of indicator:
L(LED) (10x38mm only) with
built in LED diode which
blinks after the fuse-link
operates. The internal circuit
resistance is 2M, thus the
total dissipation is minimal.
The indicator is capable of
operating in conditions of
open circuit with minimum
capacitance be-tween con-
nection cables. Operating
voltage range spans from
50V to 690V AC and DC.
I(NEON) (10x38mm only)
with neon lamp, which is
constantly lit after the fuse-
link operates. The internal
circuit resistance is 570k,
thus it is necessary that the
circuit be closed in order for
the indicator to function. The
operational voltage range is
100 V to 750 V AC.

ACCESSORIES
FUSE BASE
Fuse Bases hold fuses in place and
insure proper electrical connections.
Available in one or three pole designs.
Three-pole Fuse Bases are supplied
with two Separator Plates which should
be installed between poles. We recom-
mend the use of End Plates and
Terminal Covers for increased safety.
END PLATE
End Plates increase safety and provide
separation between devices. Install by
inserting End Plate into mounting entry
slot on right or left side of Fuse Base.
We recommend installing one End Plate
on each side of the Fuse Base.
TERMINAL COVER
Covers increase safety by covering the
conducting metal hardware of the Fuse
Base and the Fuse. We suggest
Terminal Covers be used in conjunction
with End Plates. To install slide Terminal
Cover over terminal slot and snap in
place.
MICROSWITCH
Microswitches can be field mounted on
NH fuses for remote blown fuse indica-
tion. (Sketch below)
FUSE HANDLE
We strongly suggest using the Fuse
Handle when inserting or removing fuses
from the Fuse Base to prevent electrical
shocks. For increased safety, use Fuse
Handle with integral safety glove. Both
Fuse Handles are for use with NH-Knife
