BK1/HFB-10

Fuseholders are commonly used to secure circuit protection components like fuses, fuse links and other overcurrent devices. One of the most commonly used fuseholders is the BK1/HFB-10. Widely used in industrial and automotive applications, this device is designed to ensure optimal protection of circuits. In this article, we discuss the application field and working principle of the BK1/HFB-10.

The BK1/HFB-10 is mainly used in automotive and industrial applications. Its rated currents range from 100A-800A, perfect for heavy-duty applications. In industrial environments, it can be used for large current flows, motor control circuits, and power supplies for large machinery. In automotive applications, it can be used for protection of on-board DC circuits, including components such as electric motors, pumps, radiators, and batteries.

The BK1/HFB-10 features a simple push-button contact handle and an easy-to-use releasing mechanism, making it easier to operate than other fuseholders. It also has a special insulation design to prevent electric short circuits. This insulation material also ensures a long lifespan of the fuseholder, even when used in harsh environments.

The BK1/HFB-10 features a one-piece contact structure with an improved current carrying capacity. It also has a low contactal resistance and fast installation. Additionally, the steel bell housing of the fuse holder provides a sturdy mount for the fuse, allowing it to be mounted in even the most challenging of environments.

The working principle of the BK1/HFB-10 is relatively straightforward. When an overcurrent is detected, the thermal trip element present in the fuseholder melts. This melts the fuse link, causing the current to be stopped and disrupted. The force of the current causes an internal contact in the fuseholder to open, preventing further current flow and protecting the circuit from damage.

In summary, the BK1/HFB-10 fuseholder is typically used in automotive and industrial applications for circuit protection. It is designed with a push-button contact handle and easy-to-use releasing mechanism that makes it easier to operate. The one-piece contact structure offers improved current carrying capacity and the steel bell housing ensures a similarly dependable and sturdy mount. Finally, the working principle involves a thermal trip element melting the fuse link when an overcurrent is detected, thereby opening the internal contacts of the fuseholder and protecting the circuit from further damage.
