BK/PCB-2-1/2-SD Application Field and Working Principle

BK/PCB-2-1/2-SD fuses are a type of fuse used to protect electrical circuits and equipment from overloads or short circuits. They are designed for shorter length applications and feature a small footprint size for increased design flexibility.

The BK/PCB-2-1/2-SD fuses are dual-element fuses that consist of two elements. The current-limiting element controls the circuit’s response time and current at overload conditions and the second element is the interrupting element which eliminates short circuits.

The current-limiting element limits the available fault current passing through the fuse. The current-limiting element is usually composed of a silver-tin or silver-gold element, depending on the requirements of the application. The current-limiting element is heated from both the current that passes through it and the induction of the current on the secondary element. When the current-limiting element exceeds its trip current, the fuse will open.

The interrupting element is made of a copper-nickel alloy and is used to interrupt the current flow without arcing. The interrupting element will “blow” before the current limiting element reaches its trip current to ensure continued protection of the circuit and the equipment.

The BK/PCB-2-1/2-SD fuse can be used in a wide range of applications. They can be used in high-impedance circuits where conventional fuses may not be suitable for protection. Additionally, they can be used to protect sensitive electronic components in various types of electronic equipment, including computers, medical devices, and communications systems.

The BK/PCB-2-1/2-SD fuse is also suitable for use in inductive loads such as motors and transformers as they can handle the higher surge and current demands. They can also be used in higher temperature environments as they have a high temperature rating and are heat-resistant.

Overall, the BK/PCB-2-1/2-SD fuse provides reliable protection for electrical circuits and equipment in a wide range of applications. Its compact design and high temperature rating make it an ideal choice for a wide variety of applications. To ensure maximum protection, it is important to choose the right fuse for the application.
