Overview
The Bussmann FRS-R-10 is a Class RK5 time-delay fuse designed for industrial and commercial circuit protection. This lot includes three 10A/600V dual-element cartridge fuses that meet UL, CSA, and CE standards. Fusetron fuses are engineered to provide coordinated protection with modern electrical equipment while minimizing nuisance trips on inrush currents.
Key Features
- Dual-element construction — time-delay design reduces false trips on motor inrush
- Class RK5 rating — current-limiting class for maximum protection against fault currents
- 200 kA interrupting rating at 600V — meets industrial circuit protection requirements
- Cartridge design — 0.81″ diameter × 5″ length with ferrule terminals for standard fuse holders
- Multiple certifications — UL, CSA, and CE approved for global compliance
