0213.315MXBP Application Field and Working Principle

The use of fuses, both in commercial and home applications, has become increasingly popular. Fuses are used primarily to prevent damage to electrical equipment, as well as to protect people and other property from electrical shock. The 0213.315MXBP fuse is a glass-bodied, UL approved medium voltage fuse. It is used most often for medium voltage circuits ranging from 5kV-1000 Amps, which includes three phase circuits, main service entrance and load centers.

Application Field

The 0213.315MXBP fuse can be used as a general-purpose protective device for medium voltage applications. This includes the protection of primary and secondary distribution equipment, such as switch gear, switch boards, electric motors, transformers, and power centers. The fuse can also be used in other medium voltage devices, such as elevators, water heaters, and commercial ovens.

It is available in a variety of AC voltages (230,400 and 575) and interrupting ratings (50kA, 100kA, and 200kA), making it suitable for a variety of medium voltage applications. The 0213.315MXBP fuse is UL-listed and approved for use in AC circuits. The UL-approval is important for a contractor to ensure that a safe job is done.

Working Principle

The 0213.315MXBP fuse works by limiting the current that can flow through it. In a standard fuse, a metal strip or wire, known as the element (also known as a fuse link), is connected between two metal plates, or contacts. When too much current passes through the element, it heats up and melts, breaking the contact between the two metal plates and thus, breaking the circuit.

The 0213.315MXBP fuse is unique because of its glass body. The glass body acts as an insulation barrier, separating the component parts of the fuse. The body also acts as a thermally-efficient container for the element, allowing it to heat up more quickly to reduce arc formation and fade-out when the circuit is overloaded. The glass body also helps to prevent foreign objects from entering the fuse and shorting it out.

The 0213.315MXBP fuse employs a "time-delay" feature. This feature allows the current to flow through the element until the overload value (current rating) is reached, at which point the fuse melts, breaking the contact and stopping the flow of electricity. This time-delay feature gives the device a short period of time to cool down and prevents it from being overloaded too quickly.

The 0213.315MXBP fuse is a cost-effective and durable fuse for medium voltage applications. In addition to being UL-approved, it also features a robust glass-body which provides added insulation protection. It is available in a variety of AC voltages and interrupting ratings, making it suitable for many medium voltage applications.
