Medium-voltage fuse / transformer - max. 200 A, 7.2 kV | Prime-MEC
Suitable choice for Transformer Protection, Condenser (Capacitor) Protection, Motor Protection
Features
The HRC Power Fuses belong to the Prime-MEC series. It interrupts high currents before the first loop of fault current has reached its natural peak value and therefore cuts down the required withstand capacity of the associated equipment on the electric system.
Though small in size, it has a high breaking capacity and its enclosed type is suitable for use inside of the panel board.
PRIME MEC fuses are equipped with striker pins for trip indicators as well as for operating the related load break switches.
Link type fuse holder enables easy maintenance and high stability when replacing the fuses.
With Fuse Checker, checking the conditions of a fuse in the panel board or by telecommunication is possible.(Optional)

Cylindrical fuse / high-voltage - HRC series
H.R.C. fuses are normally used to protect
small banks and/or three-phase capacitors, designed
in accordance with DIN and IEC standards for protection
against thermal and dynamic effects, caused by short
circuit current exceeding the tolerated value in magnitu-
de and duration.

Medium-voltage fuse / capacitor - 10 - 100 A
Expulsion fuses (see figure S) are normally used to pro-
tect banks with high powers usually installed outside,
where there are many units in parallel.
Using expulsion fuses is a practical cost-effective and
functional system since, in case of failure:
- only the unit involved is excluded, keeping the system
in service, making it possible to schedule replacement;
- searching for the affected unit is easy and fast as it
is easy to see thanks to the expulsion device, thereby
making it possible to minimize the search time (see
figure R);
- the fuse can be reused by changing only the internal
cartridge element.
We should point out that system operation, in the event
of failure and ensuing exclusion of one or more units, is
only permissible if the increase in voltage on the remai-
ning capacitors is less than 10% (minimum number of
10 units in parallel per phase).
If use involves a smaller number of units in parallel,
the bank of capacitors must be disconnected from the
network to avoid damage to the other units that are
still integral.
It is recommended to use expulsion fuses on banks
with a max power of approximately 5 Mvar; this value
is based on the need to prevent the current due to the
discharge of the energy stored in the units connected in
parallel with the defective unit causing the container
to break.
