Circuit breakers are essential components of electrical systems. They are designed to protect circuits from overloads and other potentially damaging conditions. UPL11-25778-3 is a type of circuit breaker that provides effective protection for a variety of applications. In this article, we will discuss the application field and working principle of UPL11-25778-3.

The UPL11-25778-3 circuit breaker is designed for use in low-voltage electrical systems, including motor control centers, construction sites, and home power systems. It is suitable for both indoor and outdoor applications, as it is rated for operation in temperatures ranging from -20°C to +60°C. It has a maximum voltage rating of 690V AC and a maximum current rating of 125A. The UPL11-25778-3 circuit breaker is also certified for use with Type 2 neutral links.

The working principle of UPL11-25778-3 circuit breaker is based on the concept of thermal-magnetic protection. When the current flowing through the breaker exceeds its nominal rating, the thermomagnetic switch inside the breaker trips and the contacts inside open to disconnect the power supply. This helps to protect the circuit from overloads and other dangerous situations. In addition, this type of circuit breaker is also designed to protect against short-circuiting and ground-fault conditions.

UPL11-25778-3 circuit breaker has several advantages over conventional breakers. For instance, it has a smaller footprint and is easy to install. Additionally, it is designed with an adjustable current rating, allowing users to adjust the amount of current that the breaker can handle. This feature is especially useful when the load on the circuit changes intermittently.

The UPL11-25778-3 circuit breaker is also equipped with several safety features. Its clear cover provides a visible indication that the circuit is tripped, making it easier for technicians to locate and repair faults. Furthermore, a signal contact is provided within the breaker, which can be used to indicate the tripped condition of the breaker and alert personnel.

In addition to its protective features, the UPL11-25778-3 circuit breaker also features a manual reset system. This manual system allows manual resetting of the breaker by turning the handle. This ability makes it easier to reset the breaker when needed without having to shut down the entire circuit.

Overall, UPL11-25778-3 circuit breaker is a cost-effective, reliable, and safe product. It provides effective circuit protection and is suitable for use in a variety of applications. Additionally, its manual reset system makes it easy to reset when needed. For all these reasons, UPL11-25778-3 circuit breaker is an ideal product for a wide range of circuit protection applications.
