Circuit breakers are critical components for ensuring the safe and continuous operation of electrical equipment. They are designed to prevent the excess current flow from endangering the integrity and safety of circuits and equipment, typically by disconnecting the power supply at a predetermined current level. LELZX11-35308-23-V is a type of circuit breaker specifically designed to meet the requirements of high-performance applications. In this article, we will discuss the application field and working principle of LELZX11-35308-23-V.

LELZX11-35308-23-V is a three-phase circuit breaker with rated voltage of 800V, current rating of 50A, and interrupting capacity of 100kA. It is mainly used in the fields of marine engineering, power engineering, communications engineering, and other high-performance applications. It is renowned for its reliable protection, simple operation, small size, lightweight, and energy saving features.

The working principle of LELZX11-35308-23-V is based on the characteristics of overload protection. When the current of the protected circuit exceeds the rated current, its contact structure will open automatically and quickly to disconnect the circuit. The core components of the circuit breaker include a contact structure, a moving contact, and a stationary contact. The moving contact is connected to a mechanical spring so that when the current exceeds the rated current, the spring is compressed, forcing the contact to move and break the circuit connection.

In addition to the overload protection, LELZX11-35308-23-V also provides short circuit protection. It does this by using a bimetallic strip or other heat-sensitive components. When the current is too high, the heat produced by the current will cause the bimetallic strip to heat up and deform, which will cause the contact to open and disconnect the circuit.

LELZX11-35308-23-V also provides protection against line-to-line faults. This is accomplished by using a set of three contacts, one on each of the three lines. When a fault occurs, only one of the contacts will open, preventing electricity from flowing through the faulted line.

In addition, the LELZX11-35308-23-V also provides ground fault protection. This is done by using a ground contact that is connected to the neutral line. When a ground fault occurs, the contact will open and disconnect the circuit, preventing further damage.

Finally, the LELZX11-35308-23-V also provides an electrical lockout feature. This feature locks the circuit breaker in the open position, preventing the circuit from being energized and preventing accidental activations.

In conclusion, LELZX11-35308-23-V is a reliable and high-performance circuit breaker specifically designed for use in marine, power, communications, and other demanding applications. It offers excellent protection from overloads, short circuits, line-to-line faults, and ground faults, and also includes an electrical lockout feature for added safety.
