Bussmann series Class RK5 Fuses
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).<br>
Core features
- Separate overload and short-circuit elements provide time delay for sizing as close as 125% of motor FLA while delivering excellent short-circuit protection
- 2:1 selective coordination amp ratio (within the Bussmann series RK5 fuse family) prevents overcurrent events from opening upstream Fusetron fuses
- Insulated end caps for 225A-600A fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
- Superior overload and cycling capabilities
- Current limiting provides component short-circuit protection
Benefits of Class RK5 fuses
Dual-element, time-delay fuse – 10 seconds (minimum) at 500% rated amps. Available with indication on select ratings.
