What are cartridge type fuses?
What are cartridge type fuses?
A cartridge fuse is a cylinder shaped fuse with either metal caps (ferrules) or blade contact points, at both ends. Most cartridge fuses are rated for 250 Volt to 600 Volt circuits, dependent on the class of the fuse, and rated for varying amperages as high as 600 amps, again dependent on the specific fuse.
What is a cartridge fuse used for?
Cartridge fuse is a fast type of safety device that is used to protect cables, power lines, and equipment against overloads and short circuits in electrical systems. The main function of a cartridge fuse is to protect systems and human life.
Where are the cartridge type fuse used?
Cartridge fuses are used to protect electrical appliances such as motors, air-conditions, refrigerator, pumps etc, where high voltage rating and currents are required. They are available up to 600A and 600V AC and widely used in industries, commercial as well as home distribution panels.
What does a cartridge fuse look like?
Types. Cartridge fuses are cylindrical in shape and have contact points at each end. They are rated for circuits over 30 amps and typically 240 volts. They have a cylindrical metal cap on each end and look like big versions of the fuses you find inside the plug end of holiday lights.
What size are cartridge fuses?
Cartridge Fuse Size Guide
| Length x Width | Fuse Series / Description | Voltage Range |
|---|---|---|
| 31.8 x 6.35 mm | 3AB | 125V – 1000V |
| 31.8 x 6.35 mm | 3AB | 250V – 600V |
| 31.8 x 6.35 mm | 3AG | 32V – 250V |
| 32.1 x 6.4 mm | Nato size 0 | 440V |
What is the major difference between a plug fuse and a cartridge fuse?
In residential use, the fuses protecting the circuits are of two types: plug fuses, which generally protect 120-volt circuits, and cartridge fuses, which protect 240-volt circuits, as well as being used to protect the entire electrical service.
How do you tell if a cartridge fuse is blown?
Use a multimeter to measure the resistance of cartridge fuses. Cartridge fuses look like shot-gun shells; you can test whether a cartridge fuse is blown by touching both ends of a multimeter to each end of the cartridge fuse. Low resistance is good; high resistance indicates the fuse is blown.
What is the amperage of cartridge fuse?
Cartridge fuses are cylindrical in shape and have contact points at each end. They are rated for circuits over 30 amps and typically 240 volts. There are two basic types of cartridge fuses. Ferrule-type fuses are rated up to and including 60 amps.
