This article is about the application field and working principle of SPXI03.5T, a type of specialty fuse used in electrical applications. As a special type of fuse, SPXI03.5T has unique features compared with other varieties. It is an integrated, high-current interrupting device, and contains both a fuse and a 150V AC switch, as well as protective insulation.

The primary application field for SPXI03.5T is electrical systems, where it is mainly used for circuit protection and overload prevention. This type of fuse has a 360-Amp interrupting rating, and can break currents up to 600 volts. It also offers excellent contact resistance up to 4mA.

The working principle of SPXI03.5T is relatively simple. It uses a current limiting structure to protect its contacts and components by progressively limiting current in case of a fault or overload. It does this by regulating the load’s current, and then using thermal overload protection to interrupt the circuit when the current exceeds a pre-determined amount. It also utilizes an over-voltage protection circuit to protect the fuses’ contacts from extreme voltage.

In addition to the above-mentioned protection features, SPXI03.5T has other benefits. It is easy to install and maintain, and is compatible with a wide range of electrical systems. It is also reliable and durable, with an average life expectancy of 10 years. This means that the fuse can provide reliable protection for long periods of time.

Overall, SPXI03.5T is an important and versatile variety of electric specialty fuses. Its ability to protect circuits under a wide range of current duty and temperature makes it suitable for a wide range of applications. Its ease of installation and maintenance ensures that it is easy to use, and its reliable performance proves that it is a compelling choice for electric specialty fuses.
