BK/PCB-2

BK/PCB-2 Application Field and Working Principle

BK/PCB-2 fuses are a type of Specialty Fuses, commonly used in the protection of low-voltage, low-current (1-10A) panelboards and auxiliary equipment. They are designed to provide circuit protection against overloads and short circuits, while allowing operators to quickly reset and restore the system quickly and easily following an outage.

The BK/PCB-2 Fuse is designed with a special spring-loaded indicator that automatically moves to an "open" position if a fault or interruption occurs. This indicator lets operators identify the affected circuit quickly and easily so that a reset or maintenance can be performed promptly. It also helps to provide an efficient and reliable level of circuit protection.

In addition to providing overload and short-circuit protection, BK/PCB-2 fuses use dual-element construction that allows them to be used in systems with both alternating current (AC) and direct current (DC) applications. Additionally, the dual-element design helps to reduce inrush currents and minimize heat losses.

The BK/PCB-2 fuse has a variety of applications, including in industrial, commercial, and even residential settings. Their design makes them ideal for use in panelboards, auxiliary equipment, transformers, and other equipment that uses low-voltage, low-current circuits. They are also commonly used in high-speed data communication networks and other applications that require fast-response protection.

The working principle of the BK/PCB-2 fuse is quite simple. When a fault or interruption occurs, excess current flows through the fuse element, causing it to heat up and expand. This expansion causes the indicator to open, providing a visual indication to the operator of the affected circuit. The element is also designed to automatically reset if the fault is corrected without needing manual intervention.

The BK/PCB-2 fuse is an effective and reliable tool for providing circuit protection for low-voltage, low-current circuits. Its quick-response indicator and dual-element construction make it ideal for a variety of applications, providing an efficient and reliable level of protection.
