Bussmann FRN-R-20 Dual Element Time-Delay Fuses

• 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
