RS400P is an important component in the field of fuses. It is mainly used for current overheat protection and overload protection. This article will discuss the application field and working principle of the RS400P fuse.

What is RS400P Fuse?

The RS400P fuse is a single-phase DC fuse made of UL 94V-0 flame retardant materials. It is strategically designed and manufactured to combine low internal resistance, high current capacity, easy installation and reliable performance. Its base is made of hardened steel and can withstand a strong mechanical shock. It has a unique vacuum-forming process and excellent electrical properties.

Applications of RS400P Fuse

RS400P fuses are widely used in the circuit of electronic apparatus, DC motor protection and monitoring, short circuit and overload protection in telecommunication equipment, computers, automatic production lines, automotive electronics and other fields.

The RS400P fuse provides reliable protection for the circuit by quickly disconnecting the current when it is overheat or overload. In addition, it can be applied for various forms of automatic equipment due to its good adaptability. This provides a higher level of safety when operating those machines. It also helps reduce the size and weight of the circuit and, therefore, the cost.

How RS400P Fuse Works

The RS400P fuse is a thermal-magnetic fuse that provides both thermal and overload protection. When the current rating exceeds the design specifications, the fuse will disconnect the circuit. It will also disconnect the circuit when the system temperature rises beyond the allowed limit.

When the fuse is connected to the circuit, its thermal element warms up and expands according to the current run through the circuit. When the current is beyond the designed limit, the temperature rises, causing the thermal element to expand even more, causing the current to be disconnected. When the current is lower than the allowed limit, the thermal element will cool down and slowly contract until it disconnects the power.

The RS400P fuse also has a magnetic element integrated into it. This magnetic component interacts with an internal mini-rectifier, which increases sensitivity and reduces power loss. When the current is too high, the magnetic element will attract the mini-rectifier, causing an increase in the current, resulting in a proportionally larger amount of current to be cut off. To further increase reliability, all models of RS400P fuse are tested to ensure their ability to withstand high temperatures and electrical shocks.

Conclusion

In conclusion, RS400P is a highly reliable and efficient single-phase DC fuse that provides both thermal and overload protection. Its various features make it suitable for use in various applications, such as electronic apparatus, DC motor protection, telecommunication equipment, computers, automatic production lines and automotive electronics. In addition, its unique design allows for easy installation, lower power loss and a higher capacity for current. It also helps reduce the size and cost of the circuit. Thus, it is widely used in various fields.
