Medium and high voltage power fuses provide a reliable and economical means of protecting small to medium size power transformers, potential transformers, station service transformers, and capacitor banks. The lower installed cost of a power fuse, it's compact size, and the fact that no auxiliary equipment (batteries, motor drives, protective relays, etc.) is required make it the ideal choice for applications where cost and space are key concerns and infrequent operation is expected.
The robust construction of Southern States Type BP, BPA, and HPA power fuses provide 3 full fault operations before tube replacement is required, a significant savings in total life cost vs. other power fuses which require tube replacement after each fault regardless of fault magnitude.
Southern States power fuses and power fuse kits are available from 7.2 kV thru 169 kV with ratings up to 400 E and interrupting ratings to 40 kA RMS Asymmetrical. Distribution Fuse links are also offered at 27 kV and below.
