BK/S505-V-3.15R

BK/S505-V-3.15R application field and working principle

BK/S505-V-3.15R is an industrial mid-range fuse that is widely used in machinery, electronics, communications and other fields. It is a three-pole, three-phase fuse, categorized as a group of LV fuses, with a rated voltage of up to 3.15kV.

Application Field

The industrial fuse BK/S505-V-3.15R is mainly used in industrial power distribution systems, machinery equipment, electronics, and communications. Its wide application field includes:

• Power transformer protection: This includes three-phase ground fault protection, overload protection, short circuit protection, and other protections.
• Automotive protection: This includes startups, overloads, and short-circuits.
• Other protections: This includes the protection of semiconductor apparatus and electronic equipment.

Working Principle

The BK/S505-V-3.15R is an effective component used in a range of medium voltage applications such as automated switchgear enclosures, fusing units, and switchgear assemblies. The fuse capability is enhanced with a 15kV time-delay fuse. These are designed to protect against a sustained overload or short-circuit current, allowing the fault current to be safely interrupted.

The primary function of the fuse is to provide protection against electrical overloads or shorts. Overloads occur when there is a difference in the electrical current between the fuse and the source - such as a faulty cable. When the electric current flowing through the fuse exceeds the rated value, it’s designed to open, protecting the system from damage.

Additionally, when there is a short-circuit between two or more of the conductors of a system, the current will be much higher than normal. In this case, the fuse is designed to open quickly to cut off the electric current, thus preventing any potential damage.

The BK/S505-V-3.15R offers required electrical disconnection, by interrupting the current flow without arcing or further damage. This fuse offers reliable performance even under extreme overloading conditions, due to its solid silver link material and superior quality.

Conclusion

The BK/S505-V-3.15R is a reliable medium voltage fuse commonly used in a wide range of industrial applications. It has proven to be an effective component for discouraging overloads and short circuits thanks to its design and solid silver link material. Its 15kV time-delay fuse adds further protection against sustained overloads and short-circuits, ensuring the safe interruption of the fault current.
