BK/MDL-1/4RX

BK/MDL-1/4RX Application Field and Working Principle

A BK/MDL-1/4RX is a class of fuse that is used in many industries. It is designed to protect circuits and components against short circuits and overloads. This type of fuse offers a range of features including high rated long-time current capabilities, excellent protection, and low-power dissipation.

The BK/MDL-1/4RX is generally used in circuits with rated current up to 40A. It is suitable for voltages up to 250V AC and 380V DC. The fuse is capable of withstanding instantaneous currents up to 15 times its rated current, making it suitable for protecting circuits from short-term over current transients.

In terms of application fields, the fuse is applied to the circuits of AC motors, transformers, switches, rectifiers, voltage regulators, starters, cablerail systems, and circuit panels.

Working Principle

The principle of BK/MDL-1/4RX fuses is based on the concept of inductance. The fuse consists of an inductive core and an associated winding, which produces an electrical field when a current flows through it. When the current exceeds the rated current, a “short-circuit” is created, dissipating the excess energy as heat.

The BK/MDL-1/4RX fuse does not open until the short-circuit temperature has exceeded the melting point of the fuse element, making the fuse suitable for applications with long-term over-currents. Additionally, the fuse is also designed to prevent the over-heating of components due to high currents.

Conclusion

The BK/MDL-1/4RX is a popular type of fuse, thanks to its range of features and its suitability for a wide variety of applications. Its ability to withstandInstantaneous currents up to 15 times its rated current makes it suitable for protecting circuits from over-currents, while its design helps to prevent the over-heating of components due to high currents.
