Bussmann KGJ-100 Fuse

The Bussmann KGJ-100 is a fast-acting capacitor fuse rated for 100 A and 600 V AC, with an interrupt rating of 200 kA. Manufactured under the Bussmann brand (Eaton’s Bussmann line), the KGJ-100 is designed to protect capacitor banks in electrical systems by rapidly interrupting fault currents that could damage capacitors or surrounding circuitry. This device carries a 100 A current rating and is intended for operation up to 600 V AC, delivering a high interrupt capability of 200 kA to clear severe fault conditions quickly and help preserve circuit integrity. As a dedicated capacitor protection fuse, the KGJ-100 supports reliable safeguarding in power electronics and distribution arrangements where capacitors are employed, helping to limit fault energy and protect adjacent components from damage in industrial and commercial electrical installations.
