Eaton Bussmann HD Time Delay Fuse 8 Amp - Slow Blow Fuse for Home Appliances, HVAC Systems & Electrical Equipment Protection

FRN-R-8 - Eaton/Bussmann HD Time Delay Fuse - 8 Amp is a heavy-duty time-delay fuse used in motor protection. When sized correctly it helps protect motors from burnout caused by overloads and single-phasing. The time-delay feature allows the initial start-up current surge for typical motors to pass but opens before motor burnout occurs if a long, dangerous overload is present.

Additionally, the dual-element design opens within 0.004 seconds when the fuse is short-circuited. UL Listed Class R (IR: 200kA). Groove in end cap or notch in knife blade permits the fuse to be used in Class H, Class K, or Class R fuse blocks. Cartridge fuses are used to protect motors and branch circuits where higher amps or volt ratings are required. They are available in a wide variety of sizes, amp and volt ratings up to 600Vac and 600 amps.

Cartridge fuses are used extensively in commercial, industrial and agricultural applications as well as residential fuse panels, air conditioning, pumps, appliances, and other equipment. Cartridge fuses are available in two types. General Purpose fuses have no time delay and protect fuse panels, appliances, and branch circuits. Heavy-duty fuses have a time-delay feature, allowing momentary motor startups. Both are available in 250Vac and 600Vac versions with catalog symbol and amp rating stamped on the knife blade or end cap.

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
