Introduction

Circuit breakers are an important electrical component used in a variety of applications. The CMLBXPK111-1RLS4-40351-225-V is a type of circuit breaker whose application field and working principle will be explored in this article.

Application Field

The CMLBXPK111-1RLS4-40351-225-V is designed to be used as an overload protection device in electrical distribution systems. This type of circuit breaker is often employed in industrial and commercial environments and found in electrical control panels, switchboards, and substations. It is also suitable for residential applications due to its robust and reliable design.This breaker is suitable for alternating current ratings between 5 amps and 225 amps and can be used in both single-phase and three-phase systems. It is perfect for use in applications with long lines and transformers, and it also boasts a quick response time and high interrupting rating. The breaker also features a robust and reliable construction with an operating temperature range of -25°C to +50°C. It is designed to protect against overloads, short circuits, and ground fault conditions.

Working Principle

The CMLBXPK111-1RLS4-40351-225-V circuit breaker is based on a thermal-magnetic operating principle. This type of circuit breaker has two main components; a mechanically operated switch and a thermal-magnetic protection element. When an overload current is introduced, a bimetal is heated by the current. When this occurs, the bimetal bends due to the thermal expansion and actuates the mechanically operated switch, which then trips the breaker. This action causes the contacts of the breaker to open, thereby interrupting the flow of current.The thermal-magnetic protection element of the breaker is also important. This protection element contains a magnetic coil, which detects changes in current and causes the switch to trip under certain conditions. If the current flowing through the circuit exceeds a predetermined value, the magnetic coil becomes saturated and the breaker trips. If the current is too low, the current fails to trip and the breaker stays closed.

Conclusion

The CMLBXPK111-1RLS4-40351-225-V is a robust and reliable type of circuit breaker ideal for a variety of applications. It can be used in industrial, commercial, or residential environments and can handle alternating current ratings between 5 amps and 225 amps. The breaker is based on a thermal-magnetic operating principle and works by using a bimetal and a magnetic coil to detect overloads and trip the breaker.
