Circuit Breakers

UPL41-5275-7 circuit breaker is a device designed for electrical safety, to break an electrical circuit under preset abnormal conditions. The primary purpose of UPL41-5275-7 circuit breaker is to interrupt any circuit receiving too much current, to prevent those damages or fires due to overload, or short/leakage of current. The right way to ensuring a safe electrical system is by preventative maintenance and regularly inspecting the circuit breakers that are in used.

Application Field

With the modernization of industries, electrical systems have become increasingly more crucial for any operation. UPL41-5275-7 circuit breakers are the most widely used type of electrical protection device in industrial and commercial settings. It is ideal for heavy industrial applications, commercial buildings, and renewable energy installations. Its advanced features make it beneficial for many high-tech applications, such as power supplies, transformers, and switchgear.

The UPL41-5275-7 circuit breaker offers reliable protection for people and property by providing overload, short circuit and ground fault protection. Its modular design allows for easy installation and maintenance. The UL489 safety switch prevents accidental contact with the housing and protects against electric shock. The switch also has an IP20 rating for indoor use in an environment up to 50℃.

Working Principle

UPL41-5275-7 circuit breaker works by tripping when a fault or overload condition occurs. It is designed with a thermal release that melts at a predetermined temperature, when the surrounding temperature increases due to current overload. When the melted thermal release allows the spring to move, the contact of the circuit breaker open.

UPL41-5275-7 circuit breaker also works on radio frequency interference (RFI) and transient protection. The RFI filtering eliminates signals from entering the system, maintaining the natural balance of the system. The transient protection guards against any sudden surges in voltage.

The UPL41-5275-7 circuit breaker also works on ground fault protection, which is necessary for safety. The ground fault protection monitors the amount of flow current going into and out of electrical devices, as well as the amount of earth leakage and leakage current. If the amount of earth leakage exceeds a set limit, the flow of the current is stopped, protecting the system from any potential faults.

Conclusion

UPL41-5275-7 circuit breaker is a reliable protection device for industrial and commercial settings. It is designed with a thermal release that melts at a predetermined temperature when the surrounding temperature increases due to current overload. Furthermore, it also has advanced features such as, RFI filtering, transient protection and ground fault protection. With its advanced features, UPL41-5275-7 circuit breaker is the ideal choice for heavy industrial applications, commercial buildings, and renewable energy installations.
