H.R.C. Fuse Fittings & Fuse Bases
STS
Make moulded fuse fittings are available in very wide range i.e.
20Amp., 63., and 100 Amp. The fittings are moulded close type and safe
clip type. Open type fuse bases are suitable from size 00 to size 03 in
high grade Phonemic Compound as well as in Dough Moulding Compound.
They are suitable for front wiring and both end but back connected type
SNP available in 20 Amp., only. Type SNF 20/32 Amp., is design to
accumulated with both bolted panel and direct 35 mm DIN rail mounting
features.
H.R.C. Fuse Fittings & Fuse Bases
Group A:-
Close
type fuse fittings are suitable for off-set tag fuses. 20/32 Amp. fuse
fitting are available with front/busbar and rear connection arrangement
while 32 Amp. & 100 Amp. rating are suitable for front and busbar
connections. Ample contact area with non ferrous high pressure backing
plates ensure low temperature rise. A minimum number of component have
been used tus insuring simplicity of design and reliability in
operation. Moulded components are manufactured from electrical grade of
phenolic powder. An aperture has been provided on the top of the
carrier of the quick indication of fuse operation without removing the
carrier.
Group B:-
SNF
20/32 Amp. safe clip type fuse fitting is design to accommodate with
both bolted panel and a direct 35 mm DIN RAIL mounting. the product is
suitable to the compact rant of off-set type blade tag fuse link. The
product is very significant in saving of time and power loss. Easy
removable of fuse carrier from the fuse base is possible with the help
of a cam lock arrangement. Fabulous and unique looking carrier having
cam locking arrangement without carrier contact provides very low
wattage loss due to low contact resistance between the fuse link and
base contact.
Group C:-
Open
Type Fuse bases are available in 100 Amp. 250 Amp. 40 Amp & 630 Amp
in this range. The moulded components are manufactured in Phenolic
Compound as well as in Dough Moulded Compound. Contacts are silver
plated thus keep the contact resistance to the minimum. Lyre shape
contact and spring loaded contact generate on the fuse blades resulting
in very low temperature rise.
