Bussmann Fusetron™ FRS-R-90 Advanced Protection Current Limiting Energy Efficient Low Voltage Time Delay Fuse, 90 A, 600 VAC/300 VDC, 20/200 kA Interrupt, RK5 Class, Cartridge Body

Short Description

Time delay affords the same excellent overload protection as low peak fuses of motors and other type loads and circuits having temporary inrush currents such as those caused by transformers and solenoids. (In such circuits, Limitron fuses can only provide short circuit protection). Fusetron™ fuses are not as Fast-Acting on short circuits as low peak fuses and therefore cannot give as high a degree of component short circuit protection. Like the Low-Peak™ fuse, Fusetron™ fuses permit the use of smaller size and less costly switches. Fusetron™ fuses fit rejection type fuse holders and can also be installed in holders for Class H fuses. They can physically and electrically replace Class H, K5, and other Class RK5 fuses.

Features
  • 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
  • Time delay of 10 s (minimum) at 500% of 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
  • Gives motor running back-up protection to motors without extra cost
  • 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 over current protection
  • Provides a good deg of short circuit protection (greater current limitation) to help protect downstream components from high fault currents
  • Simplifies and improves blackout prevention (selective co-ordination ratios)
  • Insulated end caps reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
  • Renewable
  • 200 kA at 600 VAC rms symmetrical, 20 kA at 300 VDC interrupt rating
