D-type
( Bottle Type )
HRC Fuse system with current ratings from 2A
to 100A with
breaking capacity of 51 KA at 500 V AC & 4
KA at 250 VDC
Salient
Features
1. Conforms to : IS : 8187 - 1976
2. HRC Properties : Rupturing Capacity : 51
KA at 500 V AC / 4 KA at 250 V DC. |

3.
Two modes of Operations & Selectivity :
Fuse-links are available for
Quick Action & Delayed Action. Delayed
action fuse links are selective in ration 1:2 with all fuse links
complying with the requirements for the
operating class gG, no matter which system
is involved. While in
Quick Action fuse links it is not possible to
specify a relationship since these fuses conforms solely to VDE 0635, IEC 241
where l-t curves have not been established upto
the higher short circuit current Level.
4. Time Current Range : gG to IEC - 269 - 2, 269
- 3
5. Non-interchangeability : The bases are provided
with gauge pieces which do not accommodate the
insertion of a higher rated fuse link. Thereby higher rated fuse
links cannot be used by mistake. These
gauge pieces can be fitted with the help of
a special spanner.
6. Colour Coding :
The gauge pieces and fuse
link trip indicators for different current
ratings are colour coded as per Indian and International standards.
Thereby fuses can be correctly replaced even
when the blown out fuses are lost.
7. Locking / Sealing Holes :
Three holes are provided in
the fuse carrier. The motion of the fuse
carriers in the opening direction can be restrained by passing a wire
through these holes and sealing the wire.
8. Access from a distance : The fuse carriers are so
designed that they can be inserted or withdrawn
with the use of a long stick fitted with a special adaptor.
Thereby one can have an access
9. Quick Replacement :
The downtime during
replacement is minimum in these fuses and no
hand tools or special pullers are needed for replacement of fuse links

CA1,
BA2 to BA5 Type (Clip & Bolted Type Fixing)
HRC Fuse System with current ratings from 2
A to 200 A with
bases having breaking capacity 50 kA at 500 VAC.
Salient
Features
BL - Fusegear CA1, BA2 to BA5 type HRC Fuse
have the following salient features.
|
A.
High breaking capacity to the tune of 80 KA as a
result, they are suitable for the use in
existing complex
industrial net work.
B. Cool running of the system as the watt
loss values are well below the specified limits
of national and international Standards.
C. Eliminate the risk of fire and damage
to personnel equipments.
D. Ensure continuity of supply to healthy
circuits in the events of faults, as the
specially designed elements provide positive discrimination.
E. Performance remains unaltered
throughout the service life.
F. Designed to suit Indian and Tropical
climatic conditions. |

SALIENT FEATURES
:
Switching
reliability : BL-NH-HRC Fuse Links are
tested for switching reliability in complete
range of application. They perfectly master low over currents
with sufficient heat generation and medium short
circuit
currents with maximum pressure stressing.
Cut of characteristics
BL-NH HRC Fuse Links have a current limiting
effect. They interrupt the short circuit
current while it is
increasing and do not allow the current to reach
its peak value. |
