How Much Do You Know About Fuse Classification?

1. Current fuse

Chip fuses are available in specifications such as 0805 and 1206. Utilizing thin-film technology for precise control of electrical characteristics, their compact size makes them an ideal secondary protection solution for circuits in space-constrained applications, such as handheld portable electronic devices and various instruments.

Insert fuse. Commonly seen in automotive applications, sometimes also known as fork bolt fuses

Tubular fuse. This is very common, especially in various power supply applications such as switch mode power supplies.

2、 Temperature fuse.

It is an irreversible disposable thermal protection device, available in series such as RH, RF, RY, etc. The product has a delicate appearance structure, good sealing, sensitive and reliable operating temperature, small current impact, and vibration resistance. It is mainly used in electric fans, rice cookers, electric frying pans, disinfection cabinets, etc.

RH square temperature fuse. The appearance is a plastic square shell shape, with a block type temperature fuse, generally in the form of a low melting point alloy

RP resistance type temperature fuse, generally in the form of low melting point alloy

RY metal shell temperature fuse. Using metal as the shell and organic chemicals as the heating element, it has sensitive induction, accurate action, sealed structure, and reliable performance. Used for rice cookers, hair dryers, electric motors, etc

3、 Self healing fuse.

This is an automatically recoverable fuse that causes an open circuit state due to excessive current. It belongs to the multiple use type and is suitable for overload protection circuits.
