S505-2-R Application Field and Working Principle

The S505-2-R fuse is a single pole type fuse used when dismantling the circuit. It can be divided into electric plug-in type, electric knob type and DIN rail mounting type. It has the characteristics of safety, reliability, high breaking capacity and strong short-circuit protection performance. It is widely used in communication products, instrumentation, automotive, transformer substations, power distribution boxes and other places.

Working principle: S505-2-R fuse is an overcurrent protection device in electrical circuit. Its function is to prevent the continuous increase of the flow of the circuit and avoid the consequences caused by the increase of the current (short-circuit, fire, etc.). Its working principle is very simple. Under normal working conditions, the current flowing through the fuse element is small and the resistance is small. When the current in the circuit increases abruptly, the heat generated by the current flowing through the fuse is larger than the heat dissipated by conduction. When the temperature rises, the melting metal is melted, and the molten metal flows out, form a virtual circuit to cut off the current, so that the current is no longer circulated, so that the circuit is disconnected and the function of overcurrent protection is achieved.

The S505-2-R fuse has a large breaking capacity and short-circuit protection performance. It has high safety, high reliability, stable performance and long working life, making it the most suitable choice for circuit overload protection. The S505-2-R fuse has four main focuses: safety, reliability, high breaking capacity, and short-circuit protection performance. Its maximum short-circuit current is 1.xx times. Its rated current is 0.xxA, which is adapted for various electrical and electronic equipment.

In conclusion, the S505-2-R fuse provides electricity to the circuit, stopping the ever-increasing flow of current, thus avoiding short-circuit, excessive power and fire hazard. Its working principle is simple, and its rated and short-circuit current is adaptable for various electrical and electronic equipment. It also has the advantages of high breaking capacity, high safety, high reliability, and long service life. With its features, the S505-2-R fuse is widely used in communication products, instrumentation, automotive, transformer substation and power distribution box.
