The FRN-R-10 - Eaton/Bussmann Heavy-Duty Time Delay Fuse - 10 Amp is an RK5 fuse that protects against motor overload, ground faults, and short circuits. When sized correctly it helps protect motors from burnout caused by overloads and single-phasing.

Reduces the risk of motor burnout resulting from single-phasing in 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.

Overload protection is provided by the overload element, which holds an overload five times greater than the ampere rating of the fuse for a minimum of ten seconds.

Features

• Provides motor overload, ground fault & short-circuit protection
• Helps protect motors against burnout from overloads
• Helps protect motors against burnout from single-phasing on 3-phase systems
• Simplifies & improves blackout prevention (selective coordination)
• Dual-element fuses can be applied in circuits subject to temporary motor overloads & surge currents to provide both high performances short-circuit & overload protection
• The overload element provides protection against low-level overcurrent of overloads & will hold an overload that is 5 times greater than the ampere rating of the fuse for a minimum of 10 seconds
