Horizontal Mount Fuse Holder PTF-50 For 5x20mm Cylindrical Cartridge Fuse Link 6.3A 250V

Description

According to the application environment, ampfort fuse holder is divided into: mechanical panel special type, circuit board installation, wiring harness type fuse cartridge/box. Panel-specific types usually have 5X20, 6X30, 10X38, etc.; circuit boards usually use fuse clips or horizontal (cubic shape) for easy replacement, and the applicable fuse sizes are generally 3.6X10, 5X20, 6X25 British, 6X30; the other is the application For electronic wiring harness products, it is usually suitable for 5X20, 6X30, 10X38 size fuses. Its commonly used models are: R3-9, R3-11, R3-12, R3-13, R3-22, R3-54, H3-9, H3-11, H3-12, H3-13, OP520, OP530, PTF -15, PTF-25, PTF-78, BLX-A, CQ-200C, CQ-201N, fuse clip (3X10, 5X20, 6X30, 10X38), F520 bakelite/nylon cable barrel, etc. Products have passed UL CSA VDE UR CCC S FI PSE TUV certification, etc., and comply with EU ROHS environmental protection standards.

Basic knowledge of R3 series fuse holders

The fuse holder refers to the holder where the fuse is installed. The place where the fuse holder needs to be installed is not only convenient to replace the fuse, but also from a safety perspective. The existence of the fuse holder is obviously very necessary.

Fuse holders can be divided into panel-mounted fuse holders, PCB-mounted fuse holders, lead-type fuse holders and automobile fuse holders if they are divided into major categories; this chapter focuses on understanding panel-type fuse holders.

R3 series Fuse Holder

As the name suggests, the panel type fuse holder is installed on the panel. It needs to be tailored according to the size of the fuse holder. It needs to be designed to install and fix the card, and it must be in the same way, otherwise it will not be installed. This is also the unique feature of the panel fuse holder. The difference between it and other fuse holders is that the tolerance can not be very large, otherwise it will cause installation failure.

The most representative panel type fuse holder is the R3 series fuse holder. R3 is an international model. Only R3 is mentioned. I think there is nothing unfamiliar in the industry. Moreover, the R3 series installation and installation fuse size division is also divided into 5×20mm Fuse holder, 6×30mm fuse holder,10x38mm fuse holder, currently 5X20mm is the most widely used, the most representative 5X20mm is R3-12, this is a very large amount, as well as R3-11, R3-14 and so on. 6×30mm fuse holders are currently in high demand on many chopping boards, and the most representative ones are R3-9, R3-13, etc. The most representative 10x38mm fuse holders are R-18, R3-41, etc. This type of fuse holder is relatively large and has a large installation size, so its use is slightly less than other size fuse holders. It is generally installed in Special working environment, such as high-current chopping board such as high voltage and high temperature.

Whether it is R3 series fuse holders or other styles of fuse holders, they must have current resistance, voltage resistance, and fire resistance requirements, and generally need to pass UL CSA VDE ROHS and other safety regulations and EU certification.
Although the R3 series are very commonly used circuit protection components, companies will gradually reduce the use of R3 series because of cost and other issues. However, this is a market law. Our production companies must also follow its rules. Customers only need to choose You can fit the fuse holder yourself.Yes, the others are second. When we choose the R3 series, we mainly look at the installation size, the size, shape and performance of the suitable fuse tube.
