5MTP 3.5 Datasheet/PDFFuses
A fuse is a safety device that acts as a protective device in the electrical and electronic devices. It is designed to melt and break the circuit during an electrical overload or short circuit. It prevents excessive current from damaging the circuit and the device connected to it.
Fuses are made in two main types; they are cartridge and blade. Cartridge fuses have two metal contacts which face each other and are joined by a metal wire that melts when excessive current is encountered. The Blade fuse has two metal blades which are joined by a spring-like action when excessive current is encountered.
5MTP 3.5 Application Field and Working Principle
The 5MTP 3.5 is a type of Cartridge fuse used mainly in automotive applications. It is designed with a ceramic body, two nickel-plated contacts and an aluminum cap for protection from environmental elements. The standard amperage rating of the 5MTP 3.5 is 30 amps, although higher amperage can be used when needed. The 5MTP 3.5 has a breaking capacity of 3,000 A, which means it can protect the circuit from excessive current that could potentially cause damage.
In normal operation, the fuse is unblocked, and the current passes through without any drop in voltage. However, when an overload occurs, the current exceeds its limit, the metal wire in the fuse melts, and the two contacts get separated, thus cutting off the supply of current to the circuit and protecting it from damage.
The 5MTP 3.5 has various applications in the automotive industry, including fuel pumps, fuel injectors, fan motors, power windows, and airbag systems. It is also used to protect the battery from overcharging. The resettable fuse is also used in other applications such as power supplies, medical equipment, and consumer electronics.
The 5MTP 3.5 is used mainly in automotive applications due to its reliable performance and fast response time. It is also designed to be easy to install and remove. Furthermore, the 5MTP 3.5 fuse is durable since it is protected from environmental elements and its contacts are nickel-plated for corrosion resistance.
