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

Fuses are an integral part of electrical systems, as they provide protection against overloads that can cause significant damage to equipment. BK/PCB-1-1/2-SD fuses are a type of fuse specifically designed to protect Fiber Optic Communication and Automation Equipment.

Application Field

The BK/PCB-1-1/2-SD fuse is designed to provide overtemperature and overcurrent protection in fiber optic communication and automation systems. It is also suitable for protecting connected equipment such as circuit boards, batteries, and more. It can be applied to a wide variety of applications such as data centers, servers, fire and security monitoring systems, and more.

Working Principle

BK/PCB-1-1/2-SD fuses operate on the principle of thermal-magnetic protection. This means that when the current load reaches a certain threshold, a magnetic field is generated that creates a mechanical force on a metal strip of the fuse. The metal strip buckles and breaks, disconnecting the circuit and limiting current loading, providing over-current protection. When temperatures rise, a bi-metallic strip of the fuse will bend, again disconnecting the circuit and preventing temperatures from rising any further.

BK/PCB-1-1/2-SD fuses feature arc-quenching chambers. In the event of an arcing fault, the chamber rapidly reduces oxygen levels, which in turn reduces the temperature of the arc, terminating it. The fuse is then reset automatically and ready for reuse. The fuse also features self-resetting mechanism, which allows it to reset automatically after the fault has been cleared.

BK/PCB-1-1/2-SD fuses also have a wide operating temperature range, making them compatible with a range of environments. They are designed to comply with BS EN60269 safety regulations, ensuring a safe and reliable operation.

Conclusion

The BK/PCB-1-1/2-SD fuse is designed to provide over-temperature and over-current protection in a variety of applications. It operates on the principle of thermal-magnetic protection, and features arc-quenching chambers and self-resetting mechanisms. The fuse is BS EN60269 compliant, making it a safe and reliable product. It is suitable for protecting connected equipment such as circuit boards, batteries, and more.
