FUSETRON™ 250V Class RK5 FRN-R — 250Vac/125Vdc, 1⁄10-60A, Dual Element, Time-Delay Fuses Dimensions - in 2" (± 0.31) 3" (± 0.31) 0.56" (±0.008) 0.81" (±0.008) 1/10 to 30A Description: Advanced protection, energy efficient Class RK5 dual element, current-limiting, time-delay fuses with optional open fuse indication on select ratings. Time-delay – 10 seconds (minimum) at 500% of rated current (8 seconds for 1⁄10-30A sizes). Catalog Symbol: FRN-R-(amp) (non-indicating) FRN-R-(amp)ID (indicating) Ratings: Volts — 250Vac, 125Vdc Amps — 1⁄10-60 Amps IR — 200kA Vac RMS Sym. — 20kA Vdc Agency Information: Fuse Amps 0-30 CSA Certified, C22.2 No. 248.12, Class 1422-02, File 53787 Catalog Numbers (amps) — Non-indictaing fuses FRN-R-18⁄10 FRN-R-2 FRN-R-21⁄4 FRN-R-21⁄2 FRN-R-28⁄10 FRN-R-3 FRN-R-32⁄10 FRN-R-31⁄2 FRN-R-4 FRN-R-41⁄2 FRN-R-5 FRN-R-56⁄10 FRN-R-6 FRN-R-61⁄4 FRN-R-7 FRN-R-71⁄2 Features: • Provides motor overload, ground fault and short-circuit protection • Helps protect motors against burnout from overloads • Helps protect motors against burnout from single-phasing on three-phase systems • Simplifies and improves blackout prevention (selective coordination) • Dual-element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide both high performance short-circuit and overload protection • The overload element provides protection against low level overcurrent of overloads and will hold an overload which is five times greater than the ampere rating of the fuse for a minimum of ten seconds.
