Bussmann High speed fuses protect sensitive devices and power semiconductors from short-circuits, and are specifically designed to minimize the I2t, peak let-through current and arc voltage. Our new Bussmann series compact Bussmann High speed fuses protect compact drives, power conversion and UPS equipment. These 50-400 amp fuses require up to 48% less enclosure space when compared with traditional high speed, round body fuses without compromising heat rise performance.

Bussmann High speed fuses series full range DFJ high speed, current-limiting fuses provide overload and short-circuit protection for variable speed drives and electric controllers, and meet NEC ® branch circuit protection requirements. The DFJ drive fuse has the lowest I2t of any UL branch circuit fuse in the industry to protect power semiconductor devices that utilize diodes, GTOs, SCRs and SSRs.

Bussmann High speed fuses provide superior protection or isolation for components such as diodes, silicon controlled rectifiers (SCRs), Gate torn-Off Thrusters (GTOs) and IGBTs and in light and heavy harsh DC traction applications as high as 4000Vdc and 10,000A. Also used for the protection of DC link/power converters, Optimized dimensions and materials allow for excellent thermal dissipation for high current cycling environments, or heavy duty applications.
