Bussmann Fusetron™ FRN-R-250 Advanced Protection Current Limiting Energy Efficient Low Voltage Time Delay Fuse, 250 A, 250 V AC/125 V DC, 20/200 kA Interrupt, RK5 Class, Cartridge Body
Bussmann Fusetron™ FRN-R-250 Advanced Protection Current Limiting Energy Efficient Low Voltage Time Delay Fuse, 250 A, 250 V AC/125 V DC, 20/200 kA Interrupt, RK5 Class, Cartridge Body
Bussmann's UL Class RK5 Fusetron product offering provides energy efficient advanced protection with its dual-element, time-delay construction and is available with optional open fuse indication on select ratings. Available in both 250Vac and 600Vac, 200kA RMS Sym interrupting rating and sizes ranging from 0 to 600 amp. Fusetron's deliver 10 seconds (minimum) of time-delay at 500 of rated current (8 seconds for 1/10-30A sizes).
Bussmann Fusetron™ Time Delay Fuse, Advanced Protection Current Limiting Energy Efficient Low Voltage, Series: FRN-R, Indicating/Non-Indicating: Non-Indicating, Rejection/Non-Rejection: Rejection, 250 A, 250 V AC/125 V DC, 20/200 kA Interrupt, Class: RK5, 10 s at 500% Response, Blade Terminal, Holder Mount, Cartridge Body Type, Dual Element, Fiberglass, 2.38 in Dia x 8.63 in L Body Size
Features
- Provides motor overload, ground fault and short circuit protection
- Helps protect motors against burnout from overloads, single phasing on 1 ph systems
- Simplifies and improves blackout prevention (selective co-ordination 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
- The overload element provides protection against low level over current of overloads and will hold an overload which is five times greater than the ampere rating of the fuse for a minimum of 10 s at 500% of rated current
- Insulated end caps for 225 to 600 A fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
- 200 kA at 250 VAC rms symmetrical, 20 kA at 250 VDC interrupt rating
