Cartridge Fuses

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.

FRN-R and FRS-R Heavy-Duty Time-Delay Fuses

Now FRN-R Fuses Available with easy ID™ Blown Fuse Indication!

FRN-R and FRS-R Heavy-Duty Time-Delay Fuses

Used in motor protection. When sized correctly, they help 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 FRN-R easy ID™ option helps locate the blown fuse faster.
In addition, the dual-element design opens in as little as 0.004 second if the fuse experiences short-circuit conditions. All fuses UL Listed Class R (IR: 200kA). Groove in end cap or notch in knife blade permit the fuse to be used in Class H, Class K or Class R fuse blocks.

Midget Fuses

Midget fuses are 13/32” x 11/2” cartridge fuses available in a wide variety of volt and amp ratings to provide supplemental protection to industrial, commercial, agricultural, heating, ventilating and air conditioning equipment. Due to their small size, midget fuses are often used to protect internalcomponents such as control circuit wiring, motor control transformers or small motors. The National Electrical Code® now requires more protection of internal components. This will lead to increased replacement demand for these fuses.

Class CC

The rejection versions of Midget fuses are Class CC and are suitable for both branch circuit and supplemental protection.

Specialty Class G SC Rejection Fuses

600Vac Fast-Acting (1/2-6A)/ 600Vac Time-Delay (7-20A)/ 480Vac Time-Delay (25-60A)

Specialty Class G SC Rejection Fuses

These highly compact branch circuit fuses are used in residential, mobile home and industrial applications. They have a minimum 300 volt rating and are available up to 60A. All SC fuses are 13/32” in diameter with varying lengths to provide a rejection feature that prevents over fusing (installing a
30 amp fuse in a 20A circuit). One half to 6A SC fuses are fast-acting, while 7 to 60A SC fuses are time-delay to permit temporary overloads to pass without nuisance openings.
