Red Spot Fuse Fittings
■
■
■
■
Fuse fittings to AS2005.21.2 – 1990, BS88: Part 2: 1988, 660 volts AC/DC.
Approved by leading authorities and used in equipment approved by Lloyds.
Full Shrouding for personnel
safety and complete compliance
with the direct contact electric
shock requirements.
Insulating sleeves are fitted to
front connected fuse bases to
provide increased protection at
the cable entry point.
Separate base contact insulating
shrouds of great strength and
flexibility ensure that no “live”
metal is dangerously exposed
when the fuse carrier is removed.
Anti-vibration features protect
against release of a fuse-carrier
due to vibration in service. In the
400 amp size this includes a safety
catch which automatically locks on
the insertion of the fuse carrier.

Method of Cabling
Front connected 63 amp fuse fitting
Front connected fuse fittings
1. Remove red nylon insulating shroud to release cable sleeve.
2. Remove cable sleeve.
3. Fit cable sleeve over cable.
4. Fit conductor into fuse base terminal and tighten cable clamping screw to
secure. If flexible cables are used, their relatively fine strands may be given
increased protection by the use of thin wall copper ferrules over the conductor.
The following should be taken into account:
a) The inside diameter of the thin wall copper ferrule should match that of the
bared conductor end as closely as possible.
b) The length of the thin wall copper ferrule should match that of the tunnel in
the fuse base terminal.
c) The wall thickness of the ferrule should be thin enough for the ferrule to be
compressed by the tightening of the cable clamping screw. The flexible
conductors will then be consolidated within the deformed ferrule.
5. Replace red nylon shroud taking care that it holds the cable sleeve in position
by locating the shroud in the groove in the sleeves.

Suitable for busbar mounting with 185mm spacing between busbar centres.
Cable connection at the top or bottom can be achieved by simply turning
the base moulding of the contacts upside down, while the panel aperture
remains unchanged.
Removable fuse carrier allows easy mounting.
Equal mounting conditions allow combination with size 00 strip fuseaways.
Complete protection against electric shock in on- and off-position in
accordance with German accident prevention legislation (VBG4).
Connection of conductors by means of cable lugs or direct connecting terminals.
The hinged cover holding the fuse-link is “parked” in the off-position – this means
visible disconnection.
Latch-in elements for fixing to the panel.
All 3 phases of the 3-pole switchable strip fusaways are switched simultaneously.
Hinged cover of 3-pole switchable version can be barred and locked.

Applications
RSL FUSE HOLDERS
Short circuit and overload protection when used with T-C HRC fuse links.
■ 1000VAC heating and lighting circuits (mining).
■ Capacitor circuits.
■ A.C. and D.C. motor circuits.
■ Cable overload protection. T-C fuses with minimum fusing currents of
1.5-1-6In will protect cables (PVC insulated copper) when the fuse fitted is
equal to or less than the cable rating.
■ Short circuit cable protection offered to PVC insulated copper cables
i.e. I2t=K2S2, where I = current which causes fuse to operate in 5 seconds,
t = 5 seconds, K = 115, S = conductor cross sectional area in mm2.
