BK/C519-2A Fuses Application Field and Working Principles

BK/C519-2A fuses, also known as mini power line limiters (MPL) are described by the classification standard UL 7719. These type of fuses are designed for applications such as photovoltaic panel and electric vehicle power supplies, power inverters, and motor controls. They provide a level of protection from energizing and over-current conditions that is specific to the installation and operating conditions of the device or system.

Working Principle

The BK/C519-2A fused system works by allowing a predetermined amount of current to pass through the fuse, while limiting any excess current. The current limits can be set anywhere within the UL 7719 requirement range, from 0.1–2 A, depending on the specific application. To protect circuits, the relays of the fuse can be set for normal operation and over-current conditions, which opens and stops the flow of the current if it exceeds the overloaded limit.The BK/C519-2A fuse system acts as a shield to dangerous current levels and to protect or disconnect the circuitry in the case of an over-current situation. When the current exceeds the specifications of the fuse, the heat generated causes a cut-off, and the fuse is replaced. In case of a short circuit, the reverse current thwarts the action of the fuse and the reverse current circuit is broken automatically to ensure the safety of the electrical systems.

Field Applications

Due to their use in a variety of applications, the BK/C519-2A fuses have become one of the most popular fuse types in the industry, particularly in photovoltaic and electric vehicle power supplies, power inverters, and motor control systems.In photovoltaic systems, the BK/C519-2A fuses are ideal for protecting vital components from damage caused by short circuits, preventing arc-flashes, and providing safe and reliable electric functioning. These fuses are used to protect the sensitive inverters, grid connections, and cables from overload current.In electric vehicle transport, the BK/C519-2A fused system is used to protect the high power connections from developing dangerous electric arcs. The fuse provides optimum safety and reliability during operation while preventing over-voltage conditions.Finally, BK/C519-2A fuses are also widely used in motor control systems to protect the motor and control panel against over-voltage conditions or surges caused by the motor start-up. The fuse also serves as a disconnection switch for the power supply and motor if the system is overloaded.

Conclusion

BK/C519-2A fuses are UL 7719 certified and one of the most popular fuse types used in a variety of applications from photovoltaic and motor control systems to electric vehicle power supplies. They are used to protect vital components from damage due to short circuits, to provide safe and reliable electric functioning, and to prevent over-voltage conditions or surges from developing. By setting current limits within the specified range, these fuses serve as a reliable form of protection of the circuit, allowing the user to ensure safe and efficient operation of their electrical systems.
