FAQs
To install the FRN-R-17-1/2ID, locate a compatible RK5 fuse holder in the control panel, align the fuse with the bus bars, and press firmly until seated. Verify the amperage rating (17.5 A) matches the circuit requirements, and ensure voltage rating compatibility (250 Vac / 125 Vdc). Consider using the standard 3 in length and 0.81 in width to fit the designated slot and maintain proper clearance for safe operation.
Its time-delay, dual-element design minimizes nuisance trips during motor startup while providing reliable short-circuit interruption. The 17.5 A rating suits mid-sized control circuits, and the high interrupt rating (200 kAIC at 250 Vac) ensures robust protection under fault conditions. This combination reduces downtime and extends panel life in motor-driven processes.
Yes. The FRN-R-17-1/2ID fuse is part of Eaton’s RK5 family and is CE marked, ensuring compliance with European standards. Its classifier and construction align with RK5 fuse requirements, enabling consistent performance across many industrial applications while simplifying procurement and documentation for regulatory reviews.
This fuse is CE marked, indicating conformity with applicable European directives for electrical protection devices. It belongs to the Class RK5 family, which defines the fuse’s form factor and performance characteristics. While not every region may require RK5, CE marking provides a recognized compliance baseline for many international projects.
The dual-element, time-delay design reduces nuisance trips during startup, lowering unplanned downtime and maintenance costs. The fuse’s high interrupt rating improves fault protection, potentially reducing panel damage and replacement costs. Combined with easy installation and long service life, this can translate into lower total cost of ownership in manufacturing environments.
