FAQs
Yes. The FRS-R-1-8/10 features ferrule-end x ferrule-end connections and a compact 5 inch length, making it straightforward to wire in standard control panels. Its 0.81 in width and 0.81 in height support dense installations, while the 1.8 A rating suits low-current control circuits without compromising protection.
This fuse provides 1.8 A amperage, 600 Vac / 300 Vdc voltage ratings, and a high interrupt capacity of 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc. It is a time-delay, dual-element device designed to tolerate inrush while protecting against faults in industrial systems.
Best suited for motor starters, panel boards, and automation power distribution in industrial automation, machine control, and process equipment. The Class RK5, CE marking, and ferrule-end connections support OEM builds and panel shop assembly across manufacturing environments requiring reliable, compliant protection.
The FRS-R-1-8/10 is CE marked, indicating conformity with EU safety and performance directives. While it does not list SIL or IP certifications, CE marking ensures compatibility with European regulatory expectations and supports cross-border procurement for global facilities.
By tolerating startup surges with time-delay operation while delivering strong fault protection, it reduces nuisance trips and unplanned downtime. The reliable 5 inch ferrule-end design also speeds replacement and reduces wiring errors, contributing to lower maintenance labor and improved overall equipment effectiveness (OEE).
