Fuses are electrical components that protect circuits from overload or short circuit, providing a cost-effective solution for home and industrial wiring protection. The PCB-2-1/2-R model is a fast-acting fuse specifically designed for controlling and protecting personal computers. Its contact gap is 0.075 inches (1.905 mm), divided into two positions with a fast-acting response time. PCB-2-1/2-R fast-acting fuses are available in voltage ratings ranging from 250 to 600 volts, and carry interrupting ratings of up to 10 kiloamperes (KA) at rated voltage.

The primary application of the PCB-2-1/2-R is in profesional-grade personal computers, mainly for the purpose of controlling primary or secondary power supplies. It is also used to protect personal computers from lightning-related electrical surges. Additionally, due to its fast-acting response time, it can also be used for protection of any underlying circuits from an excessively high current. Furthermore, the PCB-2-1/2-R is designed to trip quickly when subjected to a fault current, ensuring that underlying circuits are protected from short-circuits.

The working principle of the PCB-2-1/2-R relies on the melting of a fuse element inside the component. This element is made from a conductive alloy, and it is precisely designed to melt at a certain current. When the current that passes through the panel is too high, the heat produced by the excess current will cause the fuse element to melt, effectively breaking the circuit and preventing further damage.

The PCB-2-1/2-R fuse also features a slow-acting response, which is designed to prevent circuit overload due to current spikes. This is achieved by the thermal expansion of the fuse element, which causes the contacts to open slowly rather than blow instantly. This increased response time is especially useful in cases of short-term overloads and transient voltage surges.

Overall, the PCB-2-1/2-R fast-acting fuse provides reliable protection for a wide variety of electronic application areas. With its two-position contact gap and fast response time, it is well-suited for controlling and protecting personal computers and other delicate electronic circuitry. Its slow-acting response also ensures that it can handle sudden overloads and transient voltage surges without tripping, making it a useful component in the overall design of a reliable power supply.
