BK/S501-V-4-R

Fuses

Fuses are a type of electrical component that protects electrical circuits from excessive currents, which can cause excess heat or fires in the event of a surge or short circuit. The BK/S501-V-4-R fuses are high-performance, low voltage dropout fuses, designed for voltage-sensitive applications.

BK/S501-V-4-R Application Field and Working Principle

BK/S501-V-4-R fuses are commonly used for switching applications, DC power distribution, and to protect primary power lines and high-current circuits in a wide range of industries and applications, including telecommunications, data centers, automotive, and energy/utilities. The fuse is designed to protect downstream components from voltage or current surges, while allowing the fuse to operate at full rated load current.

The BK/S501-V-4-R fuses use an electrothermal film as the principle of cutting off the power supply when an over-current flows through it. When the current is higher than the rated current, the temperature will rapidly increase, when the temperature reaches the limit (which is set by design), the electrothermal film will inflammatory quickly, accompanied by the molecular chain broken, lead to the rapid vaporization or oxidation of the Tin-film fuse, forming an arc, so as to interrupt the circuit instantaneous, and then to achieve the purpose of breaking off the current. Within milliseconds, the fuse will be blown.

The design of the BK/S501-V-4-R fuse is optimized to provide a high level of performance and reliability in applications where low voltage dropout needs to be maintained, such as in data centers and telecommunications networks, or where current sensing is required.

The fuse is also designed to provide the highest level of safety, with the metal fuse body containing the mechanism used to cut the power in case of an over-current event. The fuse is also designed for ease of installation, as it can simply be dropped into an existing device or line, with no need for external wiring or other installation components.

BK/S501-V-4-R fuses are designed to be used as part of a multi-pole protection scheme, as they are able to safely isolate a circuit in case of an over-current event without tripping the entire system and creating unnecessary downtime. The fuse is able to safely trip before any other downstream components are affected.

The BK/S501-V-4-R is also designed for use in critical applications, as it is able to maintain its rated load over its full operating range without tripping, ensuring that the circuit is protected against over-current events. The design also ensures a rapid response time, as the fuse will be able to trip in a matter of milliseconds.

In summary, the BK/S501-V-4-R is a high performance, reliable fuse designed for use in critical switching applications. The low voltage dropout design allows the fuse to operate at full rated load current, while the high level of safety and rapid response time ensures that the circuit is protected against over-current events without affecting downstream components.
