Our expulsion cut-out fuses are single venting devices for vertical
cross arm or pole mounting specially designed to work in outdoor
areas to provide protection in overhead distribution systems for
voltage rating from 6 kV to 36 kV. They are available with single,
double or supplementary porcelain or polymeric insulator to increase
the creepage distance.
They are provided with hooks for fixing the "on load
break stick" in parallel with the fuse holder. To assure
the permanent contact of the fuse holder, during the
making operation, a witty guide system is provided in
the lower hinge that gradually reduces the upper contact
balancing. This system enables to expedite the making
operation, that can be practically done from any angle.
The fuse links used are of type K and T manufactured
only from high quality material such as special coated
arc-quenching tubes or pure silver fuse element. They
can be interchanged with any expulsion cut-out fuse available
on the market
Our expulsion cut-out fuses are interchangeable with
those of the same rated characteristics available on
They can be used as off-load disconnector exchanging the fuse holder for a
brass disconnecting blade available with a rated current of 200 A.
Our expulsion cut-out fuses were satisfactorily type
tested at CESI laboratories (Milano) and other test laboratories
according to the latest standards.
