Circuit breakers are essential components of any electrical system. They are primarily used to protect the electrical system from overloads, short circuits, and other dangerous situations by automatically de-energizing the circuit when necessary. 1E03UM is a type of circuit breaker designed for use in medium and high-voltage power systems. It is a high-performance circuit breaker which is capable of handling short-circuit current up to 100kA, making it suitable for use in a variety of different applications.

The 1E03UM circuit breaker is composed of two main components – the breaker itself and a monitoring system. The breaker is composed of two equal and separate parts – the main contacts, which are connected to the electrical power and close to break the circuit, and the arc chutes, which separate the two main contacts and contain the arc generated during the disconnection process. The monitoring system is composed of several different components, such as a breaker position indicator, a voltage transformer, and a current transformer. All of these components work together to provide data about the status of the circuit breaker and the system it is protecting.

The 1E03UM circuit breaker operates based on the standard principles of circuit breaker design. When an overload or short circuit occurs, high current flows through the circuit and causes the breaker to trip, or turn off, the electrical power. This shuts off the power source and thus prevents an overload or short circuit from occurring. The breaker will then remain off until the power source is restored or the circuit can be repaired. The breaker also has a safety feature that will perform a self-test and shut off the power if a short circuit fault is detected.

The 1E03UM circuit breaker is most commonly used in medium and high-voltage power systems, such as those used in industrial settings and power grids. It is particularly well suited to large-scale applications, such as power plants and substations, where it can be used to protect the system from overloads, short circuits, and other dangerous situations. It is also used in industrial systems to provide protection from power loss due to equipment failure, and in medical applications, where it is used to prevent the loss of life-saving electrical equipment.

The 1E03UM circuit breaker is a reliable, high-performance circuit breaker that is capable of handling short-circuit current up to 100kA. It is a durable and reliable component that can provide effective protection for any type of electrical system, making it a popular choice for many applications.
