Circuit breakers are important electrical safety components designed to protect an electrical circuit from becoming overloaded or short-circuited due to excessive current. The 1C2.5UM application field and working principle is a circuit breaker designed to provide more accurate and efficient protection for modern electrical networks.

The 1C2.5UM is an advanced trip unit designed to be used in AC low-voltage systems with a rated operational voltage of 440-480V. It can be used for both manual and automatic applications in single- and three-pole circuit breakers. The circuit breaker offers protection against overloads, short circuits and other faults.

The 1C2.5UM works by detecting when an overcurrent or a short circuit is present in the electrical circuit and automatically tripping the circuit breaker to open the circuit and prevent further damage. The trip unit uses current-sensing technology to monitor the current flowing through the circuit. When an overcurrent or a short circuit is detected, the trip unit will activate the instantaneous trip feature, which opens the circuit breaker before the current reaches dangerous levels.

The 1C2.5UM circuit breaker also offers selectable time-delay protection. This protection allows the user to customize the protection settings to either quickly break the circuit when a short circuit is detected or to wait a certain amount of time to determine if the overload is transient before tripping. This time-delay protection helps to reduce false trips and allows users to adjust the settings depending on their application.

The 1C2.5UM\'s user-friendly LED display provides visual feedback on the state of the breaker and helps to identify potential problems. The breaker also offers protection against nuisance tripping that can be caused by operation in ambient conditions or high inrush currents. The two-pole breaker can also be set to trip both poles simultaneously or in a staggered, delayed fashion to help reduce the severity of the overcurrent and minimize the effect on other circuits.

The 1C2.5UM circuit breaker offers superior protection for modern electrical networks. Its advanced trip unit and selectable time-delay protection provide highly accurate and reliable protection, while its user-friendly LED display and built-in diagnostic features make troubleshooting and maintenance easy. The trip unit also offers protection against nuisance tripping and can be set to trip both poles simultaneously or in a staggered, delayed fashion, allowing users to adjust the breaker settings to their specific application.
