Fusetron Dual-Element Time-Delay Fuse FRN-R 1/10-60 A
Class RK5 - 250 Volt 1/10-60
Amps
FRN-R
- 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 provides protection against low level overcurrent of overloads and will hold an overload which is five times greater than the ampere rating of the fuse for a minimum of ten seconds
