Agency information:
• CE, UL® Listed, Std. 248-12, Class RK5, Guide JDDZ, File E4273
• CSA® Certified, C22.2 No. 248.12, Class 1422-02, File 53787
• CE
Features:
• Dual-element feature provides the best time-delay performance, allowing closer sizing and superior protection of motors and transformers
• Closer sizing allows for smaller fuses and less costly switches
• Class RK5 fuses with a 200 kA interrupting rating for use in a broad range of applications
• Provides motor overload, ground fault, and short-circuit protection
• Helps protect motors against burnout from overloads and single-phasing when sized properly
• 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
• Offers a 10-second time delay at 5 times the rated current
• The time-delay feature makes it possible to use fuse amp ratings that are much smaller than those of non-time delay fuses. Considerable cost savings occur by permitting the use of smaller size switches, panels, and fuses themselves.
• Provides current limitation to help protect downstream components from high fault currents.
• Gives motor running back-up protection to motors without extra costs.
Fusetron™ 600V Class RK5
FRS-R — 600 Vac/300 Vdc, 65-600 A, dual element, time-delay fuses
Catalog symbol:

Description:
Advanced protection, energy efficient Class RK5 dual element, current-limiting, time-delay fuses. Time-delay – 10 seconds (minimum) at 500% of rated current.
Specifications:
Ratings
• Volts — 600Vac, 300Vdc
• Amps — 65-600A
• Interrupting rating
• 200 kA Vac RMS Sym
• 20 kA Vdc

• CE
Features:
• Provides motor overload, ground fault and short-circuit protection. When used in circuits subject to surge currents such as those caused by motors, transformers and other inductive components, these fuses can be sized close to full-load amps to give maximum overcurrent protection
• The time-delay feature makes it possible to use fuse amp ratings which are much smaller than those of non-time delay fuses. Considerable cost saving occurs by permitting the use of smaller size switches, panels and fuses themselves
• Provides a good degree of short-circuit protection (greater current-limitation) to help protect downstream components from high fault currents
• Gives motor running back-up protection to motors without extra cost
• Helps protect motors against burnout from overloads and single-phasing when sized properly
• Simplifies and improves blackout prevention (selective coordination ratios)
• 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
