Cartridge Fuses

Cartridge fuses are safety devices designed to prevent overloads and short circuits by interrupting the power supply of higher voltages. They are supplied with dual contact points, one on each side. They are usually cylindrical and general-purpose and popular fuse types. A cartridge fuse comprises built-in resistors that trigger overload protection tasks. Furthermore, they are the most inexpensive, high-speed, and easy-to-replace fuses due to their cylindrical design. In addition, they come in various sizes and ratings with excellent compatibility features.

Why Use Cartridge Fuses?

A cartridge is a must-have safety device that offer various benefits, such as:

  • These fuses provide a considerably cheaper and more handy way to protect electrical devices from overloads and short circuits, preventing damage. 
  • Furthermore, it is worth using due to its incredibly safe nature, as they do not produce arcs, flames, or gas during burnout or break the circuit. 

How Do They Work?

These fuses are comprised of thin wires called resistors that melt during excessive current flow in the circuit. When the wire melts, it breaks the circuits and prevents the current flow. This phenomenon is referred to as "blowing out." It is relatively simple to replace the fuse to complete the circuit and restore the power supply. 

Materials and Current Ratings of Cartridge Fuses: 

Cartridge fuses are made from durable materials, like ceramic, glass, or porcelain with internal resistor wires constructed from silver, copper, zinc, or aluminium. 

When selecting fuses for your required application, it is crucial to consider the standard amperages available. It would be best to select a fuse with relatively higher ratings than the device it is used to protect. This will prevent the device from blowing even if a slight increase in power occurs. 

Types of Cartridge Fuses:

Basically, there are two types of cartridge fuses.

  • Ferrule-type fuses:

These fuses feature a cylindrical metallic cap on either end that resembles the fuses integrated into the plug ends of holiday lights. 

  • The knife-blade type fuse:

They have a similar shape to the ferrule type but consist of a flat metallic blade on each side. They are ideal for protecting circuits over 60 amps up to 600 amps.

Fuse Markings and Speed Codes:

Fuse markings and speed codes given on cartridge fuses are crucial when choosing the right fuse in terms of speed and protection of electrical equipment. The following are some of the familiar markings:

  • H = High Breaking Capacity
  • L = Low Breaking Capacity
  • FF = Very Fast Acting (Flink Flink)
  • TT = Very Slow Acting (Trage Trage)
  • F = Fast Acting (Flink)
  • T = Slow Acting (Trage)
  • M = Medium Acting (Mitteltrage)

What Are the Typical Applications of Cartridge Fuses?

The bespoke fuses are ideal for high-voltage circuits such as dryers and electric ranges. They are also widely employed to protect electrical devices where high voltage ratings and currents are needed, like:

  • Motors
  • Air-Conditions
  • Refrigerators
  • Pumps 
  • Industries
  • Commercial, and 
  • Home Distribution Panels.

Glass cartridge fuses are ideal for providing protection to devices or internal circuits from short circuits and overcurrent. They are deliberately weaker components which, when too much current is drawn, will blow. Once the fuse has blown it will need replacing in order to make the circuit complete and allow the flow of current. Features: Glass cartridge 5 x 20 mm cartridge size T Speed Rating Anti-surge Low Breaking Capacity Typical applications: Cartridge fuses are a relatively cheap way of protecting electrical equipment from short circuits and overcurrent and can be used to protect electrical appliances such as motors air-conditions, refrigerator, pumps etc. They can be found in the following areas: Industrial Commercial Home/Residential Automotive Additional Information: Why choose a glass fuse? Glass and ceramic fuses have similar properties. However you may choose a glass fuse as it enables you to see the inside of the fuse. Therefore it is easier to determine whether the fuse has blown. What size is it? 5x20 mm is a standard cartridge size and it measures approximately 20 mm long by 5 mm in diameter. They are popular in board and panel protection and will fit a compatible 5x20 fuse holder. What Speed is it? This particular fuse is “T” speed rated which means it is a slow acting fuse, sometimes referred to as anti-surge. It is able to tolerate higher levels for a short period, without shorting. Therefore, if a sudden change occurs, this fuse will not blow immediately. They are suitable for applications where a sudden flow of high current is required. What is Breaking Capacity? Breaking capacity is the level of current that the fuse can safely handle without exploding or rupturing. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit. This particular fuse is LBC (Low Breaking Capacity).

Quick Acting (F) HBC– Ceramic Fuses Ceramic fuses are great for short-circuit protection of semiconductors such as thyristors, diodes and triacs. Available in a range of current ratings with varying resistance values, this range are reliable for a broad range of applications. Note that fuses with values greater than 6.3A using open type fuse holders is recommended, to reduce the risk of nuisance tripping at or near full rated current. Why choose ceramic cartridge fuse? Ceramic and glass cartridge fuses have similar properties. The capacity of a ceramic cartridge fuse is higher than other fuses such as a glass fuse. This means ceramic fuses can be used in circuits that have a higher current and are perfect for protecting against overheating. What size is it? Sizes 8 x 32 mm, 10x38 mm, 14x51 mm & 22x58 mm in both Class gL-gG and aM are also available with a built-in striker for micro-switch operation and remote indication. Class gL-gG and aM fuse links are intended for industrial applications. All industrial fuse links are available with an operated visible fuse indicator. What is Breaking Capacity? Breaking capacity is the level of current that the fuse can safely handle without exploding or breaking. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit. What are fuses used for? • For the protection of components and equipment from costly damage used by over-current • To isolate sub-systems from the main system once a fault has appeared What is on overcurrent? It is a setting where a circuit experiences a current that is higher than the normal operating current. Very high breaking capacity Good mechanical/vibration characteristics Ceramic cartridge bodies are sand filled Typical Applications include short-circuit protection of semiconductors such as thyristors, diodes and triacs.
