0217.400MXP

Fuses are a type of electrical safety device that are designed to open an electrical circuit if an electrical surge occurs to protect the electrical components from potential damage. The 0217.400 MPX is a type of fuse that provides a reliable solution for short circuit and overload protection. This article will discuss the application field and working principle of the 0217.400 MPX.

The 0217.400 MPX is a non-reclosing fuse that is designed for residential and commercial buildings, as well as for industrial applications. It is commonly used to protect small branch circuits of 4 single-phase, and has a maximum continuous current rating of 400A. The fuse is designed to work with a voltage range of 25 Vac to 600 Vac. It is UL listed and UL Recognized, and meets the requirements of both UL 98 and UL 248-14.

The working principle of the 0217.400 MPX fuse is relatively straightforward. It is a time delay fuse, meaning that when the fuse encounters an overload current, it does not immediately activate, but rather, it takes a set amount of time to activate. This delay is determined by the current rating of the fuse, and the amount of current that has exceeded the rating. Once the current passes the rating of the fuse, the fuse will open, severing the electrical circuit and protecting downstream components from potentially damaging surges.

In addition to protecting against overloads and short circuits, the 0217.400 MPX fuse also provides protection against arc faults. Arc faults are caused by miswiring or wear in electrical circuits, and can cause serious electrical fires, damage, or injury. The 0217.400 MPX fuse is designed to sense any hazardous arcing currents and open the circuit, preventing any damage or injury.

The 0217.400 MPX fuse is a reliable and effective way of providing overload and short circuit protection for residential, commercial, and industrial applications. The time delay of the fuse makes it suitable for use in applications with a varying load, as it allows the fuse to remain operational until the load is too great and can no longer be handled safely. Its arc fault protection is also an added safety measure, helping to protect against hazardous wiring situations or wear of electrical components.

In conclusion, the 0217.400 MPX fuse is a reliable and effective solution for overload and short circuit protection. It is designed for use in applications such as residential, commercial, and industrial, and can handle a voltage range of 25 Vac to 600 Vac. The fuse is designed to provide both overload protection and arc fault protection, making it a suitable choice for many applications.
