# FUSE, 60A, 600V, TIME DELAY ![Product image](https://novapart.co/image/farnell:1696340/) **URL**: https://novapart.co/products/FLSR060.TXID/fuse-60a-600v-time-delay **SKU**: FLSR060.TXID **Manufacturer**: LITTELFUSE **Category**: Circuit Protection || Fuses & Fuse Accessories || Fuses || Industrial & Electrical Power Fuses **Price**: €15.8900 **Stock**: 10+ ## Specifications | Parameter | Value | |---|---| | Fuse Current | 60A | | Product Range | FLSR_ID Series | | Fuse Size Metric | 27mm x 139.7mm | | Fuse Size Imperial | 1-1/16" x 5-1/2" | | Voltage Rating Vac | 600VAC | | Voltage Rating Vdc | 300VDC | | Blow Characteristic | Time Delay | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:1696340/) **General Purpose Fuses** ## **FLNR_ID/FLSR_ID Indicator[®] Class RK5 Fuses** ## **250/600 VAC • Dual-Element, Time Delay • 1/10 – 600 Amperes** ## _**Applications**_ Service entrance switches Switchboard main and feeder switches Motor control center mains and motor branch circuits Individual fused combination motor controllers Distribution panelboards Industrial control panels Protection of fully rated panelboards and loadcenters All general purpose circuits ## _**Features/Benefits**_ - Reduce Downtime — A glance at the indicating window of a FLNR_ID or FLSR_ID Indicator fuse pinpoints open fuses. If the indicating strip is black, the fuse has opened. It’s that simple. - Reduce Nuisance Opening — FLNR_ID and FLSR_ID Indicator fuses have superior time-delay and cycling characteristics which can lengthen fuse life and decrease needless opening. - Reduce Fuse Inventory — Because FLNR_ID and FLSR_ID Indicator fuses have superior performance characteristics, they can be used on a variety of applications, thus decreasing fuse inventory. - Reduce Equipment Damage — FLNR_ID and FLSR_ID Indicator fuses have superior overload and short-circuit protection which can reduce equipment damage. Littelfuse FLNR_ID/FLSR_ID Indicator fuses provide blown fuse indication at a glance. The patented state-of-the-art solid state design provides maximum reliability and superior performance characteristics in a true dual-element design. The use of Indicator fuses reduces downtime and nuisance openings, increases safety, and can save thousands of dollars in lost production time. - Reduce Accidents — The FLNR_ID and FLSR_ID Indicator fuses improve safety by minimizing exposure to live circuits. Unlike other forms of blown fuse indication, it doesn’t matter if the power is on or off. No second guessing whether a light means a fuse is good or bad, and no current going across a blown fuse to power a lighted accessory. ## _**Specifications**_ ## _**Ampere Ratings**_ **Voltage Ratings:** AC: 250 Volts (FLNR_ID); 600 Volts (FLSR_ID) DC: 125 Volts (FLNR[1] ⁄10 – 30A); 125 Volts (FLNR_ID 35 – 600A); 300 Volts (FLSR_ID) **Interrupting Ratings:** AC: 200,000 am­peres rm­s sym­m­etrical 300,000 am­peres rm­s sym­m­etrical (Littelfuse self-certified) 1⁄10 – 600 am­peres Standard 248-12, Class RK5 UL Listed (File No: E81895) CSA Certified (File No: LR29862) MSHA 300 Volt Listing (FLSR_ID) QPL: Federal Specification WF-1814 **Ampere Range: Approvals:** |1⁄10**|6⁄10|18⁄10|4|8|30|80|225| |---|---|---|---|---|---|---|---| |1⁄8|8⁄10|2|41⁄2|9|35|90|250| |15⁄100|1|21⁄4|5|10|40|100|300| |2⁄10|11⁄8|21⁄2|56⁄10|12|45|110|350| |1⁄4|11⁄4|28⁄10|6|15|50|125|400| |3⁄10|14⁄10|3|61⁄4|171⁄2|60|150|450| |4⁄10|11⁄2|32⁄10|7|20|70|175|500| |1⁄2|16⁄10|31⁄2|71⁄2|25|75*|200|600| *FLSR_ID only **FLNR only Exam­ple part num­ber (series & am­perage): FLSR100ID _NOTE: For[1] ⁄10 – 30 ampere 250 volt fuses, order non-indicating FLNR series fuses.
