Cartridge fuses are low-cost electrical safety devices that are used for the overload protection of electrical circuits and appliances. They are cylindrical in shape and have a contact point at each end. Cartridge fuses are typically constructed from ceramic, glass, or porcelain. For more information on cartridge fuses please see our complete guide to <a href="https://uk.rs-online.com/web/generalDisplay.html?id=ideas-and-advice/fuses-guide">fuses</a>.RS stock a comprehensive range of cartridge fuses from industry-leading brands including Eaton, Littelfuse, Mersen and of course RS PRO.<h2>How do cartridge fuses work?</h2>Cartridge fuses contain a piece of wire that melts when too much current flows through the circuit. When the wire melts, it breaks the circuit which prevents any damage. This is often referred to as burning out or blowing out. Put simply, when a fuse blows, the circuit is broken. Once a fuse has blown, it will need replacing to make the circuit complete again and allow the flow of current.<h2>What are the different types of fuse markings and speed codes?</h2>Cylindrical cartridge fuses are used in a range of industrial, commercial, and domestic applications. Selecting the correct fuse speed is essential for the protection of your device. Here are some of the most common markings you will find on a cartridge fuse.<ul><li>FF = Very Fast Acting (Flink Flink)</li><li>F = Fast Acting (Flink)</li><li>M = Medium Acting (Mitteltrage)</li><li>T = Slow Acting (Trage)</li><li>TT = Very Slow Acting (Trage Trage)</li></ul><h2>Why use cartridge fuses?</h2>Cartridge fuses are a relatively cheap way of protecting electrical equipment from short circuits and overcurrent. They are incredibly safe as they do not produce flames, arcs, or gas when they burn out and break the circuit.<h2>What current rating should you choose?</h2>Cartridge fuses are available in a range of standard amperages. When choosing the correct fuse for your application, you should choose a fuse with a nominally higher current rating than the device that it is being used in. This means that if there is a slight, harmless power increase, the fuse will not blow.

3 Amp Fuses | RS

3a fuses (sometimes written as 3-amp fuses) are common components in many types of household and workplace plugs and other electrical devices, both in the UK and elsewhere.<h2>What are 3a fuses commonly used for?</h2>3a fuses, specifically, are most often associated with the sorts of household plugs used to supply power to smaller and less powerful appliances around the home and office.In the UK, household plugs are often fitted either with a 3a fuse (if they supply a device or appliance that's relatively low-powered), or a 13a fuse (for more power-hungry equipment and larger machinery)The general rule of thumb states that fuses will typically be rated according to the approximate power rating of the appliance they're protecting - this is why it's important to always check you're replacing a fuse with an equally rated one (assuming the one that just blew was in fact correctly rated for the device in question!)Broadly speaking, the familiar type of red 3a fuses we've all seen in many household plugs and devices are usually advised for supplying appliances that draw up to around 700 watts from the wall - this might include equipment such as:<ul><li>Standard lamps, occasional lighting and other standalone illumination fixtures and fittings</li><li>Smaller (older) or more efficient (larger, modern) TVs, DVD players, and other relatively low-draw entertainment devices</li><li>Smaller and less power-hungry kitchen appliances, e.g. fridges, freezers and blenders (as opposed to much higher-powered devices like kettles and toasters)</li><li>Various mid-range tools and workshop appliances, including soldering irons, handheld drills, jig saws and more</li></ul>

5A fuses are used in older equipment, most manufacturers have now standardised plus and fuse ratings to be either 3A or 13A.<h2>What are fuses used for?</h2>Fuses are safety devices designed to protect the electrical cable of the appliance rather than the appliance itself. Fuses are deliberately the weak link in a circuit and will blow' if an appliance or cable draws too much power, to prevent a fire occurring.You should also only replace a 5A fuse with another 5A fuse. If the fuse continues to blow do not put a higher amperage fuse in, check and correct the reason for the fuse blowing in the first place.

Glass cartridge fuses, also known as glass tube fuses, are electrical fuses that consist of a glass tube with metal caps on both ends. They are designed to protect electrical circuits from overcurrent conditions by breaking the circuit when the current exceeds a certain level. The glass tube contains a fusible element, usually made of a metal or alloy with a low melting point.When a fault occurs in the circuit, such as a short circuit or excessive current, the fusible element inside the glass cartridge fuse heats up due to the increased current flow. Once the current exceeds the fuse's rated value, the fusible element melts and breaks the circuit, effectively protecting the electrical equipment from damage.Glass cartridge fuses are available in various sizes and current ratings to match different applications and voltage levels.&nbsp;Applications<ul><li>Automotive</li><li>Residential electrical systems</li><li>Commercial and industrial electrical systems</li><li>Electronics</li><li>Power supplies</li><li>HVAC systems</li><li>Renewable energy systems</li></ul>RS stocks a wide range of glass cartridge fuses from leading suppliers such as Eaton, Littelfuse, Schurter and RS PRO.&nbsp;

Explore reliable slow-blow fuses for circuit protection. Time-delayed response for handling inrush currents. Get the right fuse at RS.

Slow Blow Fuses | RS

Slow-blow fuses, also known as time-delay fuses or time-lag fuses, are a type of electrical protection device designed to withstand temporary overcurrent conditions without immediately blowing or opening the circuit. They are different from fast-acting (fast-blow) fuses, which will quickly open the circuit in response to any overcurrent.Slow-blow fuses are typically identified by a special marking or colour code to distinguish them from fast-blow fuses. It's crucial to use the correct type of fuse for your specific application to ensure safety and proper circuit protection.<h2>Key Features of Slow-Blow fuses include:</h2><ul><li>Time Delay - slow-blow fuses are engineered to tolerate short-term overcurrent conditions that can occur during power-up or when certain electrical devices, such as motors or transformers, start. They allow these temporary surges to pass without immediately interrupting the circuit.</li><li>High Inrush Current - some electrical devices, when powered on, can draw a high inrush current for a moment before settling into their normal operating current. Slow-blow fuses are designed to handle this inrush current without blowing.</li><li>Overcurrent Protection - while slow-blow fuses offer time delay, they still provide protection against prolonged overcurrent conditions, such as a sustained short circuit. If the overcurrent persists for an extended period, the fuse will eventually open to protect the circuit.</li></ul>These fuses are commonly used in applications where momentary overcurrent&rsquo;s are expected but should not cause nuisance tripping or unnecessary interruptions. Some examples of applications that may use slow-blow fuses include electric motors, transformers, power supplies, and electronic devices with capacitors that require time to charge during startup.
