FRN-R-20

The FRN-R-20 is a 20A/250VAC class-RK5 dual element Time Delay Fuse for rejection or ordinary fuse clips. This FRN-series fuse provides motor overload, ground fault and short-circuit protection. Helps protect motors against burnout from overloads. 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 ten seconds.

• Helps protect motors against burnout from single phasing on three phase systems
• Simplifies and improves blackout prevention
• 200000A RMS symmetrical interrupt rating
