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 provides selective protection while tolerating inrush currents, reducing nuisance trips in control panels and motor drives. Business Impact → Improves uptime and equipment life, delivering consistent protection without unnecessary outages. Application → Ideal for industrial power circuits in control panels and distribution assemblies that experience startup surges. Feature → High interrupt ratings (200 kAIC at 600 Vac; 20 kAIC at 300 Vdc) enable safe interruption of large fault currents, minimizing damage to upstream equipment. Business Impact → Lowers risk of catastrophic failures and downstream component damage in demanding environments. Application → Suitable for main feeders and branch circuits in heavy-industrial installations where fault current levels are uncertain. Feature → Class RK5 construction with ferrule-end connections and a standard packaging type. Business Impact → Ensures compatibility with common RK5 fuse holders, straightforward field replacement, and reliable wiring integrity. Application → Widely used in control cabinets and distribution panels that rely on dependable, plug-and-play protection. Feature → Time-tested 3.2 A rating with 600 Vac and 300 Vdc voltage ratings supports versatile, cross-application protection. Business Impact → Simplifies part selection across mixed AC and DC circuits, reducing spare parts inventory. Application → Motor controls, drives, and mixed-voltage panel designs that demand a single, reliable protection device. Feature → Non-indicating fuse type with ferrule terminations provides a compact, low-maintenance solution for space-constrained enclosures. Business Impact → Reduces visual indicators that can complicate assemblies; combined with external monitoring strategies, it supports streamlined maintenance. Application → Automotive, industrial automation, and panel-building scenarios where external indicators or monitoring are used.

FAQs
The FRS-R-3-2/10 uses ferrule-end connections compatible with standard RK5 fuse holders. Begin by de-energizing the panel, verify correct voltage ratings, and insert the ferrule ends fully into the RK5 holder to ensure a secure, low-resistance connection. This design supports straightforward field replacement and minimizes wiring errors during maintenance.
This fuse provides an interrupt rating of up to 200 kAIC at 600 Vac, with 20 kAIC at 300 Vdc. A high interrupt rating means the fuse can safely interrupt severe fault currents without welding or causing damage to upstream equipment, which is critical for protecting transformers, drives, and feeders in industrial environments.
The FRS-R-3-2/10 is a time-delay dual-element fuse rated 3.2 A with a 600 Vac/300 Vdc rating, making it suitable for motor control circuits and other protection needs in control panels. Its time-delay characteristic accommodates motor inrush while still limiting fault current, providing a balanced protection strategy for both motors and control electronics.
The fuse carries CE marking, indicating European safety compliance and suitability for European markets. The Class RK5 designation signals adherence to a widely accepted fuse standard, ensuring compatibility with RK5 fuse holders and industry practices. These certifications matter for regulatory compliance, procurement standardization, and predictable performance in industrial installations.
The time-delay, dual-element design tolerates transient inrush without unnecessary tripping, reducing nuisance outages and improving overall uptime. This translates to fewer unwarranted panel stoppages, easier maintenance cycles, and cost savings over the fuse’s lifecycle by minimizing unnecessary replacements and service calls.
