Protection of small power transformers. Protection of potential transformers/station service transformers. Protection of capacitor banks. All ideal applications for Southern States line of expulsion power fuses. With a wide range of kV ratings (15.5 kV through 169 kV), continuous current ratings (1 A through 400 A), and interrupting ratings (8 kA asymmetrical through 40 kA asymmetrical) Southern States expulsion power fuses fit most any application. Four speed ratios--PF slow speed, PM medium speed, PX fast speed, and PE NEMA-EEI standard speed--are available to allow coordination with other system protective equipment. Four mounting arrangements--vertical, horizontal underhung, 45 degree underhung, and "V" configuration--provide maximum versatility to fit your specific installation need.
