Bussmann 170E3956 Eaton Series DC Fuse, 80A RMS, 1200 Vdc, 100 kAIC, Non-Indicating

Bussmann 170E3956 Eaton Series DC Fuse, 80A RMS, 1200 Vdc, 100 kAIC, Non-Indicating

The Bussmann 170E3956 is an Eaton Bussmann series DC fuse rated 80A RMS with a 100 kAIC interrupt rating at 1200 Vdc, built for demanding DC power protection where a high fault-current rating and a compact, non-indicating body are required. It is designed for use on DC common bus systems, DC drives, power converters and rectifiers, and reduced voltage starters, giving engineers a dependable overcurrent protection component for industrial DC power distribution. RoHS-compliant construction supports use in modern equipment designs that must meet current environmental compliance requirements.
