Eaton FRS-R-1-4/10 Fuse - Class RK5, 200 kAIC
Part Number: FRS-R-1-4/10
Quick Summary
The Eaton FRS-R-1-4/10 fuse provides time-delay, dual-element protection for panel-mounted control and motor circuits. Engineers often contend with nuisance trips during startup and inrush events, which can drive downtime and maintenance costs. CE marking is present to ensure compliance across many European installations, while the RK5 class design supports reliable coordination with Bussmann fuse blocks. This model pairs a 1.40 A rating with a 600 Vac / 300 Vdc capability and ferrule-end connections, enabling safe, rapid replacement in standard enclosures. By delivering predictable protection and a compact form factor, it helps minimize downtime and total cost of ownership in industrial controls and panel assemblies.

FAQs
The FRS-R-1-4/10 uses ferrule-end terminals and a 5 inch body designed for standard RK5 fuse blocks. Ensure the enclosure provides panel-mount space for a 0.81 in width and 0.81 in height form factor. Verify the system voltage is within 600 Vac / 300 Vdc and insert the fuse so the ferrules seat fully. Use appropriate crimp ferrules and torque guidelines per manufacturer recommendations to maintain interrupting rating and reliability.
Key specs include an amperage rating of 1.40 A, voltage rating of 600 Vac / 300 Vdc, and a high interrupt rating of 200 kAIC at 600 Vac (20 kAIC at 300 Vdc). It is a time-delay, dual-element, current-limiting fuse with a 10 second response time at 500% overload, suitable for motor and control circuits where inrush is expected.
Yes. The combination of time-delay operation, dual-element construction, and RK5 class compatibility makes the FRS-R-1-4/10 well-suited for motor protection and control circuits in panel boards. It accommodates startup inrush while providing robust short-circuit protection, reducing downtime and potential equipment damage in manufacturing lines and robotic systems.
This fuse is CE marked, indicating conformity with relevant European health, safety, and environmental requirements. It is designed to fit standard RK5 fuse blocks and is compatible with Bussmann series guidelines, supporting compliance in European and other regions that recognize CE labeling.
The FRS-R-1-4/10’s high interrupt rating and time-delay characteristics reduce nuisance trips and potential damage during startup, lowering unplanned downtime and replacement costs. Its standard ferrule-end design simplifies installation and maintenance, enabling quicker swaps in service windows and minimizing labor costs across a maintenance cycle.
