Presentation
FR-type fuses are designed to protect HV/LV power distribution transformers. Designed to be coordinated
with other equipment, these current-limiting fuses interrupt fault currents before they reach their peak. The
fault current is interrupted inside the fuse 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 aluminum end contacts
• very pure silver fuse elements
• composite material fuse element holder to withstand high temperatures
Thanks to their structure, based on a synthetic material, FR fuses are the perfect answer to the stresses
involved in use inside HV bays and fuse chambers.
