Circuit breakers are an essential part of modern electrical systems. They are used to provide overload protection, to break circuits under fault conditions, and to protect electrical equipment from damage. The 2CU10L is a type of circuit breaker specifically designed for industrial applications. This article will discuss the application field and working principle of the 2CU10L.

The 2CU10L circuit breaker is designed to be used in mission-critical industrial applications, such as those in power plants, refineries, and other critical sites. This type of circuit breaker has been designed specifically for its ability to provide reliable and comprehensive protection from both overload and short circuit events. The 2CU10L is also designed for applications where interrupt current values are high and the ambient operating temperature range is wide.

The 2CU10L circuit breaker is designed to be a reliable, low-maintenance solution for any type of industrial application. Its construction is a simple combination of several components. The 2CU10L circuit breaker has an energy-efficient main pole, a short-circuit trip unit, a device for checking thermal protection, and a manual reset switch. Each of these components has been designed to work in harmony to provide reliable protection and efficient functioning.

In its normal operating state, the 2CU10L operates as an open circuit. Current flows through the main pole with minimal resistance. When an overload or short circuit occurs, the short-circuit trip unit is activated and the main pole is closed. This causes the circuit breaker to cut off the flow of current, thus protecting the circuit and equipment from damage.

The short-circuit trip unit uses a thermal bimetallic strip that acts as the thermal element. When the circuit current exceeds the set trip value, the bimetallic strip heats up, bends, and trips the circuit breaker. This thermal protection is further reinforced by a device that checks the temperature in the circuit breaker. If the temperature exceeds a certain safe limit, it closes the circuit breaker.

The 2CU10L circuit breaker is further equipped with two additional features that enhance its reliability. First is the manual reset switch. This switch can be used to manually reset the circuit breaker after an overload or short circuit event. Secondly, the 2CU10L is fitted with an auxiliary contact that can provide an output signal when an overload or short circuit occurs, thus providing a remote indication of a fault.

In conclusion, the 2CU10L circuit breaker is an essential part of industrial applications. It has been designed to provide reliable and comprehensive protection from both overload and short circuit events. The 2CU10L is composed of several components, including an energy-efficient main pole, short-circuit trip unit, device for checking thermal protection, and manual reset switch. In addition, the 2CU10L has a manual reset switch and auxiliary contact for remote indication of a fault, thus providing maximum reliability and flexibility.
