What is FRN 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. The fuse is composed of Fiberglass tube and Brass.

What is a Fusetron?

Fusetron, 225-600 amp fuses enhance safety with insulated end caps to reduce exposure to live parts and extend air gap distance between blades of adjacent mounted fuse or to housing. Features and benefits: Time-delay Fusetron fuses are ideally suited for protecting motor and transformer loads.

What are time delay fuses?

The time-delay, or “slow blow”, fuses were developed for situations where acceptable momentary overloads are encountered, such as starting a motor. As the name implies, this type of fuse will carry an overload several times the normal load for a short period of time without blowing.

Where can I find a class Your Fuse?

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. Cartridge fuses are used to protect motors and branch circuits where higher amps or volt ratings are required.

Can a FRN 30 be used in a dryer?

No, this can’t be replaced with an FRN 30. can this fuse be used in a dryer? the fuse that came out of it is a ccmr 30 amp. what does “time delay” mean?

What kind of Fuse does a Cooper Bussmann use?

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.

What kind of Fuse is used for rk5?

Also known as dual-element fuses, these time-delay fuses withstand current overload for a short time so they won’t open when exposed to harmless temporary surges, such as when starting a motor. They have a rejection-style end design that safeguards against replacement errors. Use with Fuse Blocks for UL Class RK5 Fuses.
