BK/C515-500MA

Fuses

A fuse is a device used to protect electrical components from over current and short circuits. Fuses work by limiting the amount of current that can pass through them. When a fuse is subjected to too much current, it will melt, thus breaking the circuit and preventing the current from flowing.

BK/C515-500MA Application Field and Working Principle

The BK/C515-500MA is a medium-duty, fast-acting current-limiting fuse that is typically used for low voltage systems and high-current circuits such as power supplies, electrical ballasts, HVAC systems, automotive wiring, and electronic control systems. It is UL approved and can withstand up to 500 volts.

The BK/C515-500MA fuse is a two-piece assembly that consists of a metal vessel, typically made of copper, and a current-limiting element, typically made of metal foil or wire. The current-limiting element is wound with one or more turns of fine wire. The metal vessel acts as a thermal fuse that will melt when the current exceeds a specific rating. The melting of the metal vessel causes an interruption of the circuit, thus protecting the components from the overloaded current.

When the rated current is exceeded, the metal vessel melts and the current-limiting element begins to heat up. This causes the fine wire turns to expand, limiting the amount of current that can pass through the element. When the current is low enough, the fuse re-establishes the circuit. This is the general working principle of a fusing device.

The BK/C515-500MA is a medium-duty, fast-acting fusing device. It is specifically designed for low voltage systems and high-current circuits with ratings up to 500 volts. This type of fuse is especially suited for applications with high inrush currents and large equipment. It is also able to protect these components from short-circuits, overloads, and other forms of excessive current.

In summary, the BK/C515-500MA is a medium-duty, fast-acting current-limiting fuse that is used for low voltage systems and high-current applications. It is a two-piece assembly consisting of a metal vessel and a current-limiting element. When the rated current is exceeded, the metal vessel melts, limiting the current that can pass through the element. It is especially suited for high inrush current applications, and it can protect components from overloads, short-circuits, and other forms of excessive current.
