Capacitor Fuses
Data Sheets »

A Capacitor Fuse is a current limiting fuse with a high interrupting rating that provides both short circuit and overload protection. A capacitor fuse is designed to isolate a shorted capacitor before it can damage surrounding equipment or personnel. They are designed to protect against capacitor case rupture or dielectric failure within the capacitor. They can be used indoors in a general purpose enclosure or outdoors in a weatherproof enclosure. Capacitor fuses are non-disconnecting and require the use of a disconnect switch. They have blown fuse indication. Capacitor fuses are available in a variety of mounting options including direct, clip style and bus mount. Voltage ratings range from 1 to 9.5 kV. Current ratings range from 6 to 200 amps. Interrupting ratings range from 40 to 65 kA. They are designed in accordance with ANSI C37-41.
