Fuses are important components of any electrical system as they protect electrical circuits from damages due to high temperatures or short circuits, ensuring the safety of your equipment. The BK/MDM-6/10 is a fuse from the branded Pentaline series produced by Bussmann, and it is designed for use in common industrial applications. This article discusses the application field and working principle of BK/MDM-6/10.

Introduction

BK/MDM-6/10 is a fuse from the Pentaline series, which is a line of fuses produced by Bussmann. It is designed for individual use or in suitable mounting blocks where space is limited. This fuse is made of a non-combustible base material such as epoxy resin/involute, silicone or abrasion-resistant flour polyester, for improved safety and robust performance.

Application Field

BK/MDM-6/10 is suited for a variety of industrial applications, including motor protection, electronic equipment and general protection against overload and short-circuits. These fuses are particularly suitable for installations where space is at a premium, as they are compact and can fit into small mounting blocks or standard DIN rail mountings. This makes them perfect for applications like motor starters, adjustable speed drives, panel boards and switchgear, and all kinds of other industrial, commercial and residential devices.

BK/MDM-6/10 is also an ideal choice when used along with miniature circuit breakers (MCBs) in a parallel protection system. These fuses provide added protection for MCBs against latent defects and against damage due to overload. They also provide an additional level of safety through the detection of sustained overloads, which can be picked up by the fuses before the MCBs.

Working Principle

The BK/MDM-6/10 consists of a metallized polyimide film element surrounded by two ends of conducting material. A current rating of 10 A, at 500 VAC, is specified in the product catalogue. The safety and protection that it provides is a result of the reaction of the fuse element when exposed to an electrical current, which takes the form of an electric arc. If the current is above the rated value, the fuse element overheats and deforms, causing the fuse to open and thus breaking the circuit.

Unlike a circuit breaker which provides protection from sudden electrical overloads, fuses like BK/MDM-6/10 are also effective at providing protection from sustained overloads. This feature makes them particularly attractive to industrial users who require both high levels of safety and more accurate protection.

BK/MDM-6/10 also has an additional level of protection due to its silicone-based construction. This material is significantly more resistant to heat and arcing than traditional fuses, which can extend the life of the fuse and allow it to withstand sustained overloads with greater effectiveness.

Conclusion

BK/MDM-6/10 is a fuse from Bussmann\'s Pentaline series, designed for applications such as motor protection, electronic equipment, and generally protecting against overloads and short circuits. It provides additional protection against sustained overloads and is perfect for installations where space is at a premium. It also has an additional level of protection due to its silicone-based construction, which can extend its life and allow it to withstand short circuits with greater effectiveness.
