BK/S506-3.15A Application Field and Working Principle

Fuses are important protective components used for both industrial and domestic applications, and the BK/S506-3.15A is a fuse specifically designed to be used in high voltage power installations. This fuse offers a higher short-circuit current rating than standard fuses, and is also designed to be thermally and time-delay activated.

Application Field

The BK/S506-3.15A is a high voltage power fuse, which is designed to protect high voltage power networks from excessive overloads and short circuits. It has been tested and approved by various certification organizations, including UL, CSA, VDE, and TUV.The BK/S506-3.15A is primarily used in the following fields:

• High voltage power transmission lines
• High voltage distribution networks
• High voltage motors
• Sensitive electrical components within computers and other electrical equipment

Working Principle

The working principle of the BK/S506-3.15A fuse is relatively simple. When the current passing through the fuse exceeds the rating of the fuse, the heat generated by the excess current will cause the temperature of the fuse to rise. This rise in temperature will cause the fuse to melt and open the circuit, preventing further current from passing through the fuse.The BK/S506-3.15A contains a bimetallic strip, which is designed to react to increases in temperature. When the temperature of the bimetallic strip reaches a certain level, the strip will bend and the two halves of the fuse will disconnect, opening the circuit and preventing further current from passing through the fuse.

Conclusion

The BK/S506-3.15A fuse is a high voltage power fuse, designed to protect high voltage power networks from dangerous overloads and short circuits. This fuse utilizes a bimetallic strip that will bend when exposed to excessive heat, thus opening the circuit to prevent further current from passing through the fuse. This fuse is suitable for a number of different application fields, including high voltage power transmission lines, high voltage distribution networks, high voltage motors, and sensitive electrical components.
