Eaton FRS-R-1-1/2 Fuse - 600 Vac CE Marked
Part Number: FRS-R-1-1/2
Quick Summary
Eaton Bussmann FRS-R fuse provides time-delay protection for branch circuits in electrical panels and control cabinets. Many projects struggle with nuisance tripping and slow fault isolation, which undermines machine uptime. CE Marked compliance ensures global safety conformity, while the Class RK5 family designation confirms compatibility with standard protection schemes in industrial builds. By selecting this non-indicating, dual-element fuse with a 1.5 A rating and high interrupt capacity, maintenance costs drop and system reliability improves across a wide range of industrial processes. Its ferrule-end connections support quick field replacement and reduce downtime during routine maintenance. Designed for retrofit and new builds alike, it integrates with standard Bussmann holders and panel boards.

Bussmann series FRS-R 600 V Class R up to 60 A fuse data sheet no. 1017
Feature → Time-delay, dual-element design provides transient surge tolerance without sacrificing short-cycle protection. Business Impact → Reduces nuisance trips during motor start-ups and inrush-heavy processes, improving overall line uptime and energy efficiency. Application → Ideal for motor control centers, drives, and control panels where startup inrush would otherwise trigger premature fuse action. Feature → Class RK5, current-limiting fuse with 1.5 A rating ensures precise protection without over-fusing. Business Impact → Protects conductors and downstream components while minimizing replacement costs and downtime. Application → Suitable for branch circuits in automation cabinets and small-load feeders. Feature → High interrupt ratings: 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc support robust fault handling. Business Impact → Enhances system resilience in high-energy environments and reduces risk of equipment damage. Application → Heavy-duty industrial applications with mixed AC/DC fault scenarios. Feature → Ferrule end x ferrule end connections and 5 in length with 0.81 in width/height enable straightforward installation. Business Impact → Quick, tool-friendly replacement in standard fuse holders, reducing maintenance time. Application → Retrofit projects and new builds in control panels. Feature → CE Marking and standard packaging ensure regulatory alignment and supply-chain compatibility. Business Impact → Simplifies compliance reporting and stocking for global projects. Application → Global panel manufacturing and multi-site installations. Feature → Non-indicating fuse indicator plus time-delay operation offer maintenance teams clean integration with or without indicators. Business Impact → Improves safety and reduces diagnostic complexity during service windows. Application → Industrial automation, packaging lines, and process equipment.

FAQs
The FRS-R-1-1/2 uses ferrule-end connections and a 5 in length with 0.81 in width and height, designed for standard Bussmann holders. Ensure the holder is rated for 600 Vac and compatible with RK5 class devices. verify clearances, thermal environment, and proper alignment to avoid wiring strain during replacement.
This fuse provides a 1.5 A amperage rating with an interrupt rating of 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc. It operates as a time-delay device, with a 10-second response time at 500% overload, enabling inrush tolerance while protecting circuits from sustained faults.
Yes. The time-delay, dual-element design minimizes nuisance trips during motor startup and inrush, while the RK5 class rating ensures compatibility with common control-panel protections. Use in conjunction with properly rated conductors and motor starters to maximize uptime and protect both wiring and equipment.
The fuse is CE Marked, indicating compliance with applicable European safety requirements. It belongs to the Class RK5 family, which is a widely accepted standard for branch-circuit protection. For additional compliance needs, reference the Bussmann full-line catalogs and RoHS-related resources through Eaton’s documentation tools.
By reducing nuisance interruptions during startup and offering robust fault protection, facilities can achieve higher line uptime and lower maintenance costs. The ferrule-end design simplifies field replacements, while the high interrupt ratings protect downstream components, contributing to longer service intervals and lower total cost of ownership in automation and packaging lines.
