F227590 - FR72V16P

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 24kV fuses were specially designed with very low power losses, for use in SF6-insulated or compact air-insulated fused switchgear combinations
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.
