Fusetron™ UL Class RK5 Dual-Element, Time-Delay Fuses – FRN-R/FRS-R Series

Eaton Bussmann's series of dual-element fuses offer both 250 VAC and 600 VAC ratings and up to 600 A of protection

Image of Eaton-Bussmann's FRN-R FRS-R Series Time Delay FusesEaton Bussmann's series UL class RK5 Fusetron™ product offering provides energy-efficient advanced protection with its dual-element, time-delay construction. They are available in both 250 VAC and 600 VAC versions with a 200 kARMS Sym interrupting rating and sizes ranging from 0 A to 600 A. They deliver 10 seconds (minimum) of time delay at 500% of rated current (8 seconds for 1/10 A to 30 A sizes). Dual-element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide high-performance short-circuit and overload protection.

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 protects against low-level overcurrent of overloads and will hold an overload that is five times greater than the ampere rating of the fuse for a minimum of ten seconds
