0259.250MX913

0259.250MX913 is a medium voltage fuse used extensively in the electrical industry. It consists of three main components: fuse element, mounting, and contact. It can be manufactured in two configurations: panel mount and screw terminal. The power rating of this fuse is typically between 10 and 400 amperes and the voltage ratings range from 600 to 2400 volts AC. The fuse element is typically made of bronze, nickel, or silver and consists of a cylindrical core with two dissimilar metal strips that intersect at right angles. These strips act as fuses when they come into contact with an over-current situation, producing a large arc and thus de-energizing the circuit. The ends of the strips mount to a busbar, which in turn connects to the input/output wires, providing the electrical connection. The contact may be either a ferrous material or a non-metallic material.

The 0259.250MX913 is designed to de-energize circuits when overload or short circuit conditions occur. It interrupts the current before it reaches dangerous levels, reducing the risk of fire, flashover, and system failure. This type of fuse is usually used for applications that involve high amperage and medium voltage control circuits. Examples include lighting control, motor control, and switchgear control. Its construction is very precise and its design incorporates a few features that help enhance its performance and reliability.

One of the most important features of the 0259.250MX913 is its twofold protection. It provides protection against both overloads and short circuits, ensuring that the circuit is de-energized when either anomaly occurs. To ensure there is no overcurrent or overload, the fuse element is designed to react as soon as a current greater than the rated current is detected. This is done by allowing a current flowing through the fuse element to heat up, which causes the strips to melt and open the contact, thus de-energizing the circuit. To protect against short circuits, the fuse contains a bimetallic strip which responds to large currents by quickly deforming and collapsing, shorting out the circuit.

The 0259.250MX913 also features a unique power limiting feature. In the event of an overload, the fuse will protect the circuit by limiting the amount of power that passes through before de-energizing it. This feature makes it a great choice for protecting systems and components that are sensitive to high levels of power.

The 0259.250MX913 can be used in a wide range of applications, such as lighting control, motor control, switchgear control, and more. It provides reliable protection to circuits by quickly cutting off the power when overcurrent or short circuit conditions occur. Its design ensures that it protects against both of these conditions, while the power limiting feature helps increase system reliability.
