Circuit breakers are devices that protect electrical circuits and systems from the possibility of overloading or short-circuiting, and are essential in all types of electrical systems and installations. The LELZX12-1REC5-34186-27-V is a type of circuit breaker that is frequently used in industrial and commercial settings. This article will discuss the application field and working principle of the LELZX12-1REC5-34186-27-V circuit breaker.

The LELZX12-1REC5-34186-27-V is a type of electromagnetic circuit breaker. It is designed for use in industrial and commercial settings, such as power plants, oil and gas plants, and other industrial and commercial facilities. The breaker is suitable for use with alternating current (AC) rated voltages of up to 690 volts.

The important feature of the LELZX12-1REC5-34186-27-V is its ability to quickly detect and trip on current overloads. This is achieved through the use of a thermal-magnetic trip unit. The trip unit is connected to one or more current sensors, which detect the current flowing through the circuit. If the current exceeds a certain value, the trip unit will quickly activate, and the contacts of the circuit breaker will open, thus isolating the circuit and preventing further current flow. This is known as an overload trip.

The LELZX12-1REC5-34186-27-V also has the capability to detect and trip on short-circuiting. A short-circuit is an unintended electric connection between two points in an electrical circuit, which causes a sudden increase in the current flowing through it. The LELZX12-1REC5-34186-27-V is equipped with a magnetic trip unit, which is sensitive to the level of current flowing through the circuit. If the current exceeds a certain level, the trip unit will activate, and the contacts of the circuit breaker will open, thus isolating the circuit and preventing further current flow. This is known as a short-circuit trip.

In addition to overload and short-circuit protection, the LELZX12-1REC5-34186-27-V also offers a number of other features. It is equipped with a manual operation switch, which allows for the circuit breaker to be manually switched on and off. Additionally, it is equipped with a shunt trip, which allows for the circuit breaker to be remotely controlled using an external signal. This is useful in the event of a power failure or other emergency situation.

The LELZX12-1REC5-34186-27-V is a versatile circuit breaker, which is suitable for a wide range of industrial and commercial applications. It offers reliable overcurrent, short-circuit, and other protection, as well as manual and remote control capabilities. Therefore, it is an ideal choice for safeguarding electrical systems and installations.
