Cooper Bussmann High Speed Fuses Product Leaflet
This leaflet describes Cooper Bussmann high‑speed fuses used to protect solid‑state power equipment such as diodes, SCRs, and IGBTs. It explains the need for ultra‑current‑limiting protection, the I²t let‑through concept, and the advantages of high‑speed fuses over conventional branch‑circuit devices.
The document lists the available fuse series (Square‑Body, British Style, Ferrule, North American, and the DFJ Drive Fuse), their current and voltage ratings, UL recognition, and IEC 60269 compliance. It also covers NEC 430.52 allowances, typical circuit configurations, and performance comparisons with standard Class J fuses.
Covers: High‑Speed Fuse Fundamentals · Typical Circuit Configurations · Fuse Series and Ratings · NEC 430.52 Application · DFJ Drive Fuse Performance · Selection Guidelines

Questions answered in Cooper Bussmann manuals
Why are high‑speed fuses needed for semiconductor devices?
Semiconductor devices such as diodes and SCRs have low short‑circuit current withstand capability, so ultra current‑limiting fuses are required to limit fault energy and prevent permanent damage.
