Fuses

S500-200-R Application Field and Working Principle

Fuses are electrical components that are designed to protect electrical circuits from excessive currents. When the circuit is overloaded, the fuse melts due to the heat generated by the current, thus breaking the circuit. The S500-200-R is a low-voltage fuse commonly used in household appliances, such as microwaves, ovens, dishwashers, washing machines and refrigerators.

S500-200-R Application Field

The S500-200-R is a low-voltage fuse that is used to protect the high voltage circuits in appliances. It is designed to cut off the power supply to the appliance if the current exceeds the maximum load. The voltage rating of the fuse is 500V, and the rated current is 200A. In addition, the fuse\'s breaking capacity is 20A. Typically, the S500-200-R is used in household appliances powered by 220V AC.

S500-200-R Working Principle

The S500-200-R is a basic current-limiting fuse. It works on the principle of Joule heating, which is the process of converting electrical energy into thermal energy. When the current exceeds the maximum rated load, the fuse element heats up due to the joule heating effect and eventually melts, thereby breaking the circuit. The fuse is designed to open the circuit within a specific time period, thus preventing damage to the appliance.

The S500-200-R fuse is designed to disconnect the power to the appliance if the current increases beyond its rated capacity. However, when the current is normal, the fuse allows uninterrupted power supply to the appliance. This helps protect the appliance from damage due to overloading or short circuit.

Conclusion

The S500-200-R fuse is a low-voltage fuse that is commonly used in household appliances. It is designed to protect the appliance from damage due to overloading or short circuit. The fuse works on the principle of Joule heating, wherein when the current exceeds the rated capacity, the fuse element heats up and eventually melts, thereby breaking the circuit.
