Description
Eaton Bussmann series FRS-R fuse – Class RK5 Electrical Protection
The Eaton Bussmann series FRS-R fuse is a Class RK5 dual element, time-delay fuse designed for advanced electrical protection in industrial and commercial applications. Rated for 600 Vac and 300 Vdc, it provides reliable motor overload, ground fault, and short-circuit protection. This fuse is suitable for use in circuits subject to surge currents, such as those caused by motors and transformers, making it an essential component for electrical distributors and switchgear suppliers focused on lighting solutions, wire and cable protection, and motor control.

Features
- Dual element, current-limiting, time-delay design provides motor overload, ground fault, and short-circuit protection.
- Time-delay of 10 seconds minimum at 500% of rated current allows for temporary motor surges without nuisance blowing.
- Enables use of smaller fuse amp ratings compared to non-time delay fuses, reducing costs for switches, panels, and fuses.
- Provides high degree of short-circuit current limitation to protect downstream components.
- Offers motor running backup protection without additional cost.
- Helps prevent motor burnout from overloads and single-phasing when properly sized.
- Simplifies blackout prevention through selective coordination ratios.
- Suitable for circuits with temporary motor overloads and surge currents.
