Eaton FRS-R-3/10 Fuse - 200kAIC at 600 Vac Class RK5
Part Number: FRS-R-3/10
Quick Summary
FRS-R-3/10 is a time-delay, dual-element fuse designed to protect control panels and branch circuits in industrial automation. End users often face nuisance outages when protection is undersized or mis-specified, triggering costly downtime. CE marking confirms regulatory compliance; RoHS compliance is verifiable via Eaton's RoHS search tool, aligning with global environmental standards. This compact, ferrule-end device targets RK5-based equipment and ferrule-end terminations, delivering reliable installation in tight spaces. It provides reliable protection with predictable interruption performance across AC and DC circuits. Engineers appreciate the time-delay capability for motor loads and the dual-element design reducing nuisance trips. In procurement, the compact 5 in length and ferrule-end connections simplify stocking and replacement in retrofit projects.

Bussmann series FRS-R 600 V Class R up to 60 A fuse data sheet no. 1017
Feature: Time-delay, dual-element, current-limiting design. Business Impact: Reduces nuisance trips during motor inrush and transient overloads, improving line reliability and productivity. Application: Control panels with mixed load profiles and short-duration surges. Feature: 0.3 A amperage rating with 600 Vac and 300 Vdc voltage ratings. Business Impact: Provides precise protection for low-current control circuits while enabling safe operation on mixed AC/DC systems. Application: Industrial automation and power distribution where sensitive electronics require controlled protection. Feature: High interrupt ratings (200 kAIC at 600 Vac; 20 kAIC at 300 Vdc). Business Impact: Enhances fault-clearing capability, reducing damage risk to downstream equipment and improving panel safety. Application: Branch circuits driving motors, drivers, and other high-inrush devices. Feature: Class RK5 and ferrule end x ferrule end connections. Business Impact: Standardized protection with easy installation and compatibility in Bussmann RK5 panels, minimizing wiring changes. Application: Retrofit projects and new builds in compact, space-constrained enclosures. Feature: Non-indicating fuse with compact 5 in length (0.81 in width, 0.81 in height) and 0.152 lb weight. Business Impact: Space-efficient, lightweight protection that simplifies panel layout and reduces shipping costs. Application: Enclosures where space is at a premium and clear fuse indication is not required.

FAQs
The FRS-R-3/10 uses ferrule-end terminations designed for RK5-compatible holders. It fits in standard Bussmann RK5 panels, with a compact 5 inch body and ferrule-to-ferrule connections. Ensure adequate space for heat dissipation and verify panel clearance, mounting orientation, and correct ferrule sizing to achieve reliable connection and safe maintenance access.
This fuse provides a 0.3 A amperage rating, rated for 600 Vac and 300 Vdc. It offers a dual-element, time-delay design with a 10 second response time at 500% overload. Its interrupt ratings are 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc, making it suitable for high inrush and motor-start conditions in industrial panels.
Ideal for industrial control panels, power distribution, and motor protection circuits, especially where inrush currents are common. The RK5 class and ferrule-end connections enable reliable protection in compact panel spaces, while the time-delay feature mitigates nuisance trips during startup and transient events.
The FRS-R-3/10 is CE marked, indicating compliance with European safety and performance standards. RoHS compliance can be verified via Eaton's RoHS search tool, helping reporting and procurement teams meet environmental requirements across global operations.
With a robust interrupt rating and time-delay design, it minimizes downstream damage from faults and reduces downtime due to nuisance trips. Its standardized RK5 form factor simplifies stocking and replacements, lowering spare-part variety, accelerating maintenance, and contributing to a lower total cost of ownership in control panels.
