Fuses are essential components that protect circuits and provide additional control in the event of a fault. The BK/S504-250MA is a popular fuse due to its reliable protection and suitable design for a variety of applications. In this article, we will discuss the application field and working principle of the BK/S504-250MA.

Application Field

The BK/S504-250MA is a mid-range fuse with a 250mA current rating and a maximum voltage rating of 32V DC. This fuse is suitable for a wide range of applications including automotive, home appliances, lighting fixtures, and many other general electric installations. The fuse is designed to be used in areas where a precise current rating is required such as in energy meters, battery chargers, metering systems, and temperature control systems.

The fuse is also suitable for use in LED lighting. The low current of the fuses prevents the LEDs from overheating, which might damage them. The fuse also helps to protect the power supply from over-current and ensures that the current stays within safe levels.

The fuse is also used in power converters. It is used to limit the current that flows into a power converter so that it is kept within safe levels. This helps to protect the power converter from damage.

The BK/S504-250MA is also used in various industrial applications such as industrial motor controllers, current-sensing circuits, and voltage sensing circuits.

Working Principle

The BK/S504-250MA fuse works on the principle of over-current protection. It is a fast-acting fuse that uses a zinc-alloy element to detect and cut off the over-current. The fuse melts when the current exceeds the specified rating, which trips the fuse and cuts off the current.

The fuse has a small amount of material on the inside that is designed to heat up and melt when the current exceeds the rated current. When the material melts, the two ends of the fuse element will separate, which will cut off the circuit and protect the device.

The BK/S504-250MA fuse has several features that make it well-suited for use in a variety of applications. It has an anti-resettable function, which prevents the fuse from resetting after it has been tripped. It also has a quick-blow feature, which ensures that the fuse trips quickly when the current exceeds its rating.

The BK/S504-250MA also has an end-of-life indicator which tells users when the fuse has reached its end of life. When the end-of-life indicator indicator turns red, it means the fuse reached its rated current and must be replaced.

In conclusion, the BK/S504-250MA fuse is a reliable and flexible fuse for a broad range of applications. It is a mid-range fuse with a 250mA current rating and a maximum voltage rating of 32V DC. It works on the principle of over-current protection and has several features that make it well-suited for use in a variety of applications.
