Eaton FRS-R-35 Fuse - 200 kAIC @ 600 Vac, Class RK5
Part Number: FRS-R-35
Quick Summary
Eaton FRS-R-35 fuse is a time-delay, current-limiting device designed for motor and control circuits in industrial systems. It provides reliable overload protection while accommodating brief surge currents common in starting sequences. Engineers often struggle with nuisance trips and downtime when drives or pumps start up, or when system loads change; the FRS-R-35 helps minimize those disruptions without compromising protection. The fuse is CE marked and built on the Class RK5 platform, offering consistent performance in harsh panels and cabinets. As a low voltage branch-circuit solution with ferrule-end terminations, it also supports straightforward installation and consistent replacement in retrofit projects, improving panel reliability and maintenance planning.

FAQs
The FRS-R-35 uses ferrule-end x ferrule-end connections, which simplifies mounting in standard RK5 slots. To install, align the ferrules with existing busbars or fuse clips, tighten the end caps to the recommended torque, and verify continuity with a wiring diagram. This minimizes downtime during retrofits and ensures reliable fault isolation.
Key specs include a 35 A amperage rating, 200 kAIC interrupt rating at 600 Vac, 20 kAIC at 250 Vdc, and a time-delay (dual-element) design. These enable safe interruption during short-circuit events while tolerating motor inrush, reducing nuisance trips and protecting conductors and drives.
Yes. The FRS-R-35 is built on the Class RK5 platform with ferrule-end terminations, CE marking, and a 35 A rating, making it compatible with common RK5 fusing schemes in automation panels, MCCs, and drive protection architectures. Its dual-element design adds resilience against startup surges in automation equipment.
The FRS-R-35 is CE marked, indicating compliance with European safety and compatibility standards. This supports regulatory reviews, product approvals, and audits in facilities that require CE-certified protection devices within low-voltage electrical systems.
Investing in the FRS-R-35 yields reduced downtime from fewer nuisance trips, improved panel reliability through robust current-limiting protection, and easier maintenance with standard RK5 components. The 35 A rating paired with a high 200 kAIC interrupt capacity helps protect critical loads while enabling faster fault isolation and simpler stocking.
