Bussmann BK/FRN-R-1/2 FRN-R Fusetron, 500 mA Class RK5 Time-Delay Fuse

The Bussmann BK/FRN-R-1/2 FRN-R Fusetron is a 500 mA, Class RK5 current-limiting, time-delay fuse engineered for motor overload, ground fault, and short-circuit protection. Rated 250 Vac / 125 Vdc with a 200 kAIC interrupt rating, this dual-element fuse combines a fast short-circuit response with a time-delay characteristic that rides through normal motor inrush and temporary overloads without nuisance opening.

Key Features

  • Amperage Rating: 500 mA for precise low-current circuit protection.
  • Class RK5 Current-Limiting Design: Time-delay operation for motor overload, ground fault, and short-circuit protection.
  • Dual-Element Construction: Two internal elements provide reliable time-delay opening under sustained overloads.
  • Voltage Rating: 250 Vac, 125 Vdc for use across common AC and DC circuits.
  • Interrupt Rating: 200 kAIC at 250 Vac and 200 kAIC at 125 Vdc for high fault-current withstand capability.
  • Response Time: 8 seconds at 500% of rated current, allowing motor inrush to pass without nuisance opening.
  • Fuse Indicator: Non-indicating design.
  • Application: Motor overload, ground fault, and short-circuit protection.
