3403.0161.11

Fuses are an essential component of many electrical systems due to their ability to protect electrical circuits and equipment from dangerous levels of overload current. The 3403.0161.11 is a popular type of fuse used in industrial and residential applications. This article will discuss the application field and working principle of the 3403.0161.11.

The 3403.0161.11 is a type of fuse known as a time-delay cartridge fuse, due to its ability to delay interruption after an overcurrent event. This fuse is primarily used in industrial applications requiring reliable and robust protection against electrical faults, such as heaters, motors, and other equipment. The 3403.0161.11 is also compatible with household appliances, such as air conditioners, refrigerators, microwaves, and other large electrical appliances. Furthermore, these fuses are UL listed, which means they have been tested for safety according to UL standards.

The 3403.0161.11 has an interrupting rating of 1000 Amps and a voltage rating of 600V AC/DC. This type of fuse is composed of a one-piece, molded case and blow-out element, and is designed with a spring-loaded service block for easy installation. Furthermore, this fuse is designed with a secondary explosion vent, which reduces internal pressure and keeps the protective device intact when exposed to excessive current or arc energy. The fuse is constructed of a durable heat-resistant thermoplastic, making it suitable for up to 3500 Amps of short-circuit current.

The working principle of the 3403.0161.11 is relatively simple. When an overcurrent event occurs, the fuse element inside the cartridge will heat up due to resistive heating. The heat generated will cause the fusible element to expand, making the fuse an open circuit and thereby interrupting the electrical current. This time-delay fuse will delay the interruption long enough to prevent downstream equipment from being damaged. When the current returns to normal levels, the fuse will cool and the element will contract, allowing the current to pass through and restoring electrical power.

In conclusion, the 3403.0161.11 is a time-delay cartridge fuse used in a variety of industrial and residential applications. It has an interrupting rating of 1000 Amps and a voltage rating of 600V AC/DC, and is suitable for up to 3500 Amps of short-circuit current. This fuse is composed of a one-piece, molded case and blow-out element, and the working principle is relatively simple. When an overcurrent event occurs, the fuse will delay the interruption long enough to prevent downstream equipment from being damaged. Therefore, the 3403.0161.11 time-delay fuse is an effective and reliable protection component for electrical systems.
