Fuses are safety devices used in electrical and electronic circuits to protect them from overloads. They are made up of a metal enclosed in an outer cover with an indentation or window that allows an electrical current to pass through it when closed. The metal used in the fuse must be able to withstand the heat caused by the electrical current. In the event of an overload, the current in the fuse will be interrupted, thus preventing damage to the electrical or electronic equipment.

S506-3.15-R is a high speed fusing and pre-opening control element. It is widely used in industrial electronic equipment, digital products, auto-control systems and other products which require memory protection, high speed circuit protection and short circuit protection. Its major function is to be utilized to fuse the current when the instantaneous current of AC and DC exceeds a certain value, and then realize the safety cut-off of the circuit.

The working principle of S506-3.15-R is simple. When the instantaneous current exceeds the nominal current, the fuse element will enter a melting state due to internal thermal effect, and instantaneous resistance increases, resulting in rapid current decend. When the current is lower than the nominal current, the circuit will be in an open state. When the power is turned on and the current exceeds the nominal current, and when the current is lower than the nominal current when the power is turned off, the fuse element will be reset to its original state. Moreover, S506-3.15-R has a fast response speed and is able to reduce the emission of electrical spark when fusing.

S506-3.15-R is mainly used in various types of electrical and electronic circuits. It is mainly used as a medium and small current protection, as well as an overload protection device, in circuit systems such as central air conditioners, power distribution systems, household air conditioners, and television sets. It is also used in charging piles, automation equipment, communications systems and small UPS systems to provide overload and short circuit protection.

In conclusion, S506-3.15-R is a pre-opening and high speed fusing element that has simple structure and reliable performance. It is widely used in a variety of circuits to provide overload and short circuit protection. It is suitable for applications with AC and DC voltage ranges of 80V to 440V.
