FAQs
TCF17-1/2RN uses blade-end connections and is a dual-element, time-delay Class CF fuse. When installing, ensure proper orientation in the fuse holder, verify blade terminals are clean, and secure with compatible clips. Consider panel clearance and heat dissipation; follow standard safety practices and use appropriate PPE during replacement.
The fuse features a 17.5 A amperage rating with voltage ratings of 600 Vac and 300 Vdc. It provides 100 kAIC at 300 Vdc and 300 kAIC at 600 Vac interrupt ratings, making it suitable for high fault-current circuits. It is non-indicating and uses a dual-element current-limiting design for reliable protection.
Yes. The time-delay Class CF design accommodates motor startup surges while delivering current-limiting protection. The 17.5 A rating fits small-to-medium motors; ensure coordination with upstream protection and select devices per NEC/IEC guidelines. It integrates with common Bussmann series components and blade-end CF enclosures.
The fuse is UL Listed, CSA Certified, and CE Marked, indicating recognized safety and performance across North America and Europe. These certifications simplify procurement for regulated environments, support audits, and help validate equipment safety standards during project qualification and ongoing regulatory reporting.
The TCF17-1/2RN reduces downtime by tolerating startup surges and protecting circuits during faults, while its compact blade-end design speeds replacements. Stocking and deploying in cabinets is streamlined, lowering maintenance time and contributing to higher overall system availability and a faster payback on protective-device investments.
