Note: Many small cartridge fuses will have additional markings stamped on the end caps. The breaking capacity is the maximum current that can safely be interrupted by the fuse. The fuses the original BOM called for are ceramic cartridge fuses. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. HRC fuses will almost invariably be ceramic rather than glass. However, in this case, both buses have identical markings (CE, UL, etc...) and are sufficiently rated for any fault-situation the device could reasonably be expected to endure. Is a lightfoot halfling obscured for the purposes of hiding while in the space of another creature? Items like multimeters that are intended for mains use may have HRC fuses specified. Discuss!). It is my understanding that ceramic-tube fuses are significantly more durable, and are able to break a higher-current fault. Sometimes, a certain piece of equipment got its UL sign with one particular manufacturer and model of fuse. Slow or fast blow type fuses are and can be offered in both glass and ceramic bodies.

Either of your comments to zebonaut contain more information then this answer does. So - there must be a law against it :-). Some fuses are designated High Rupture Capacity (HRC) and are usually filled with sand or a similar material. There really are very big differences between various fuses, even when they all have the same basic rating (for example: "6.3 A, T, 250 Vac"). I have no doubt that it will perform well and in future I will definitely consider using your products again. [ Privacy Policy ], © 2019 Swe-Check Pty Ltd. All rights reserved. What are the practical differences between ceramic and glass tube cartridge fuses? As with the 3 band, I will deal with the wide band first. It may be a glass fuse with a filament, or a ceramic fuse. Strictly speaking, You would violate this UL mark using any other fuse. being the value. It only takes a minute to sign up. Not all values may be available in all types. I will deal with the type band first: If you want to know why you need a fuse, or why to replace with the correct one, see the Fuses, What and Why page.For more information on other markings found on fuses see the Fuses: The Markings page. The original fuses are going out of production. YELLOW is Very Fast Acting, means (I did know some, but I've learnt a lot myself) and came across Most fuses feature some kind of markings on the caps or label. As these fuses are larger in size, there is usually a lot more information printed on the fuse body. A rough estimate is that the best fuses have a ceramic body and contain sand to extinguish any arcs that appear when the fuse blows. A fuse may be rated at say 10A bu an initial fault condition may produce an initial surge current of 100A, or 1000A or even 10,000A. right place, read on! (Think: Sand-filled fuses vs. non-sand-filled fuses). "How soon will it melt?" $4.95. also what the meaning of various What would be the practical or safety implications of e.g. Look at the fuse rating (on the fuse itself been asked and more besides. The characteristic is termed "high rupture capacity" or HRC. Circuit Protection and Power Distribution. It would be interesting to know both what fuses specifically you are looking at and what the application is. I've had a few enquiries about coloured bands on fuses and what equipment and may be omitted from the fuse holder / circuit board If you are unable to identify the fuse, please contact us. product approval markings (refer table 3 below). Sand filling is used to absorb the energy released when melting. Internal (and some "back panel") equipment fuses are often Anti Surge BLACK is Very Slow Blow. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. BLACK is Very Slow Blow. [ Cookie Policy ]    It’s easy to tell if a glass fuse is blown; it will show scorch marks, and the filament will be melted.

My professor told us a previous version of our textbook would be okay, but has now decided that it isn't? The fuse will be one to two inches long. The L denotes that it is a low breaking capacity or glass fuse (H is High breaking capacity and is usually a ceramic package). Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. My concern would be that I don't know all of the things that might go wrong when a little fuse tries to interrupt a monstrous amount of power. How can I trick programs to believe that a recorded video is what is captured from my MacBook Pro camera in realtime? What is the difference between “Slow Blow” and “Time Delay” fuse? An arc develops in the equipment, cannot be extinguished and the resultant arc energy melts and scatters the meter or other equipment essentially explosively. Testing a ceramic fuse is the only way to tell if the fuse has blown. Generally, this should be higher than the prospective short circuit current. Table 3. 1.800.909.FUSE (3873) Toll Free. or Time Delay or even "Normal", but how to tell the difference? Using the wrong type of eg 10 A fuse can result in death - and has done so in some cases. Learn what these markings mean. information, if it is present then be sure not to use a fuse of a lower voltage rating). Why doesn’t Stockfish evaluate this fortress as 0.0? Swe-Check: The Circuit Protection Specialists. How is secrecy maintained in movie production? Our warehouse contains a vast fuse inventory, which means we usually have what you need in stock, but if we don't, the fuse can be drop shipped directly to your facility in a timely manner, same day if necessary. 5 Qty.
