UPGF66-30513-33 Circuit Protection

Circuit Breakers are an important element of modern electrical systems. They protect people, machinery, and equipment in high-voltage electrical systems by cutting off power in situations where a short circuit or an overload is detected. The UPGF66-30513-33 is a circuit breaker produced by Utico Technology that offers excellent protection for electrical systems. In this article, we will discuss the applications and working principles of the UPGF66-30513-33 circuit breaker.

Applications

The UPGF66-30513-33 is a three-pole molded case circuit breaker (MCCB). This means that it is designed to protect three separate electrical circuits from the same source of power. This makes the UPGF66-30513-33 an ideal choice for electrical systems that require safety and reliability. It can be used in a variety of applications, including residential, commercial, and industrial settings. It is also suitable for use in marine and transportation systems.

In addition to its three-pole design, the UPGF66-30513-33 also offers a range of features that make it suitable for use in a variety of applications. For example, it is equipped with trip-free and instantaneous trip functions, which provide improved safety and higher current ratings. It also has an overload protection system, which can detect high-current pulses quickly and accurately and shut down the power to protect the electrical system. In short, the UPGF66-30513-33 is a highly effective and reliable circuit breaker.

Working Principles

The UPGF66-30513-33 circuit breaker is based on the thermal magnetic principle. This means that it can detect both overloads and short circuits. Overloads are detected by a thermal element, which senses the increased heat caused by an overload. If the temperature increases beyond a certain level, the thermal element triggers the circuit breaker to shut off the power supply. Short-circuits, on the other hand, are detected by a magnetic element. If the current level exceeds a certain set point, the magnetic element triggers the circuit breaker to shut off the power.

In summary, the UPGF66-30513-33 is a three-pole molded case circuit breaker. It is suitable for use in residential, commercial, industrial, marine, and transportation settings. It is based on the thermal magnetic principle and is equipped with trip-free and instantaneous trip functions as well as an overload protection system. With its excellent protection and range of features, the UPGF66-30513-33 is an excellent choice for electricians who need reliable protection for their electrical systems.
