Feature: Time-delay, dual-element design provides selective protection for motors and power circuits, preventing nuisance trips during startup while maintaining fast fault response when faults occur. Business Impact: Improves equipment uptime and reduces maintenance costs in automated lines and packaging facilities where motors experience startup inrush. Application: Motor control centers and automated systems. Feature: Current-limiting RK5 class protection confines fault energy to downstream devices, enabling easier coordination and longer downstream component life. Business Impact: Extended equipment life and safer fault energy management, reducing downstream damage and maintenance. Application: Industrial power distribution and control panels. Feature: Ferrule-end x ferrule-end connections simplify retrofit and field installation with standard hardware. Business Impact: Faster commissioning and reduced field labor. Application: Panel upgrades and new installations. Feature: 600 Vac / 250 Vdc rating with CE marking ensures broad compatibility and regulatory compliance. Business Impact: Streamlined certification processes and safer, compliant deployments. Application: Heavy-industrial electrical systems and control circuits. Feature: Time-delay response with 10 seconds at 500% overload provides reliable protection without nuisance trips in start-up conditions. Business Impact: Predictable protection and reduced unplanned downtime. Application: Motors, conveyors, and automation equipment.

FAQs
Install the ferrule-end fuse into a compatible fuse block designed for RK5 Class devices. Ensure electrical ratings match your system (600 Vac, 50 A). Align the ferrule ends with the block terminals and secure with standard mounting hardware. Confirm the 5.5 in length fits your enclosure space before replacement.
The FRS-R-50ID has an interrupt rating of 200 kAIC at 600 Vac, providing robust fault current clearing for industrial power distributions and motor circuits.
Yes, it is a time-delay dual-element fuse. This design tolerates motor inrush and startup surges while still providing rapid protection against sustained faults, reducing nuisance trips and improving uptime in automation equipment.
The fuse measures 5.5 inches in length with a width and height of 1.6 inches. It uses ferrule-end connections on both ends for straightforward installation in standard fuse blocks and control panels.
Yes. The FRS-R-50ID is CE marked and conforms to the RK5 Class specification, aligning with common European safety standards and industry practices for industrial protection fuses.
