Bussmann FRN-R-30 Amp Brass 250-Volt Fusetron Dual Element Time-Delay RK5 Cartridge Fuse

Product Description ------------------- The Cooper Bussmann FRN-R-30 Amp Brass 250-Volt Fusetron Dual Element Time-Delay RK5 Cartridge Fuse provides motor overload, ground fault and short-circuit protection. Helps protect motors against burnout from single phasing on three phase systems. Simplifies and improves blackout prevention through 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 Fusetron Dual Element Time-Delay Fuse is a Class RK5 with a current limiting rating of 10 seconds (minimum) at 500 percent rated Amps. The overload element provides protection against low level overcurrent of overloads. The Cooper Bussmann FRN-R-30 Amp Brass 250-Volt Fusetron Dual Element Time-Delay RK5 Cartridge Fuse is UL Listed and CSA Certified. The fuse is composed of Fiberglass tube and Brass. Typical applications include power panelboards, motor control centers, combination starters, and machinery disconnects. Heavy duty time-delay fuses protect motors from burnout caused by overloads or single-phasing. The time-delay feature allows the initial startup current surge for typical motors to pass, but opens prior to motor burnout when longer, dangerous overloads are present. The dual-element design opens in as little as 0.004 second if the fuse experiences short-circuit conditions. Grooves in end caps permit the fuses 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. Used extensively in commercial, industrial and agricultural applications as well as residential fuse panels, air conditioning, pumps, appliances and other equipment. Heavy Duty fuses have a time-delay feature, allowing momentary motor startups. From the Manufacturer --------------------- Heavy duty time-delay fuse used in motor protection. When sized correctly, it helps protect motors from burnout caused by overloads or single-phasing. The time-delay feature allows the initial startup current surge for typical motors to pass, but opens prior to motor burnout when longer, dangerous overloads are present. In addition, the dual-element design opens in as little as 0.004 second if the fuse experiences short-circuit conditions. UL Listed Class R (IR: 200kA). Groove in end cap or notch in blade permit 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 blade or end cap.
