600 Amp Class RK5 Dual-Element Time Delay Fuse 600V Bussmann Fusetron FRS-R-600

The 600 Fusetron Dual Element FRS-R-600 is a high-performance fuse designed for the protection of electrical circuits. This product is part of the Bussmann brand, renowned for its expertise in fuse technology and electrical safety. The FRS-R-600 fuse is specifically engineered to operate in environments where overcurrent protection is crucial, making it suitable for a variety of industrial applications. Its dual-element design allows for the fuse to respond rapidly to short circuits while providing time delay for overload conditions. This feature helps in minimizing nuisance blow-outs, ensuring that only genuine overloads will cause the fuse to operate. Historically, the Fusetron brand has been a leader in the fuse industry since the 1960s, incorporating innovative technology to enhance safety and efficiency. The FRS series has evolved over the years to meet the increasing demands for reliability in electrical systems, especially in industrial settings. Users can commonly find the FRS-R-600 employed in manufacturing, process control, and other sectors that rely heavily on electrical equipment. Its design allows it to handle a wide range of current capacities, which adds to its versatility. The unique characteristics of the FRS-R-600 include its high interrupting rating, which allows it to safely interrupt fault currents without damaging the electrical system, and its robust construction, ensuring longevity even in harsh environments. Furthermore, it adheres to relevant safety and quality standards, providing peace of mind to users.

Manufacturer: Bussmann, now the Bussmann series of Eaton (record carries the legacy Cooper Bussmann name) Catalog Number: FRS-R-600 Product Family: Fusetron Type: Dual-element, time-delay fuse PUBLISHED RATINGS, EATON BUSSMANN FRS-R DATA SHEET Ampere Rating: 600 A Class: Class RK5 Voltage Rating: 600 Vac / 300 Vdc Interrupting Rating: 200,000 A at 600 Vac; 20,000 A at 300 Vdc Characteristic: dual-element, time-delay, current-limiting AGENCY APPROVALS AS PUBLISHED UL Listed to Standard 248-12, Class RK5, Guide JDDZ, File E4273 CSA Certified to C22.2 No. 248.12, Class 1422-01 WHAT THE CLASS DESIGNATION MEANS: Class RK5 is a rejection-style Class R fuse. Its mounting features allow it to fit standard Class H and Class K fuseholders, while a Class R rejection fuseholder will accept only a Class R fuse, so a lower interrupting rating fuse cannot be fitted in its place. The dual-element time-delay construction lets the fuse carry motor inrush and transformer magnetising current without opening, while still giving current-limiting short-circuit protection. UNPUBLISHED / NOT STATED HERE: body diameter, overall length and mounting detail (ferrule, blade or bolt hole) for the 600 A size, and the published time-delay figure at a stated percentage of rated current. Eaton's datasheet PDF could not be retrieved directly to verify those values, and no third-party figure has been substituted for them. They should be taken from Bussmann data sheet no. 1018 before the fuse is fitted or cross-referenced. Spec Basis: Eaton "Bussmann series Fusetron FRS-R 600 V Class R 65-600 A" fuse data sheet, Bussmann publication data sheet no. 1018, and the Eaton SKU catalogue entry for FRS-R-600, for the ampere and voltage ratings, interrupting ratings and the UL and CSA approval references.
