- NF/UTE Back-up Fuses
7,2kV to 24kV - Type FR
NF/UTE HV Back-up Fuses for Transformers
FR-type fuses are designed to protect HV/LV power distribution transformers.
Designed to be coordinated with other equipment, these current limiting fuse-links
interrupt fault currents before they reach their peak. The fault current is interrupted
inside the fuse-link body and although this is very fast, there is no sign of it outside.
The main elements in these fuses are: a barrel of class F insulating synthetic
material, nickel plated aluminium end contacts, pure silver fuse elements and a
composite material fuse element holder to withstand high temperatures.
Thanks to their structure, based on a synthetic material, FR fuse-links are the
perfect answer to the stress involved in use inside HV bays and fuse-link chambers.
Features Benefits
Superior mechanical strength
Outstanding withstand to operating stresses
100% synthetic structure
Average type striker: force 1 ±0.5 Joules
Back-up fuse links
High breaking capacity
High current limitation
EDF Approval which guarantees high performances and quality of fuses mani-
factured (24kV)
