Circuit Breakers are devices that can protect electrical appliances from damage caused by overloads and short circuits. The LELH111-31364-3 is one type of circuit breaker and its application field and working principle is discussed below.

The LELH111-31364-3 circuit breaker is mainly used for high-pressure circuits with a breaking current of 300 A. With being able to monitor an overvoltage of 690 VAC, it is one of the higher-end circuit breakers used for electrical protection. It is ideal for applications such as air conditioning systems, lighting systems, electrical motors, and industrial power supplies.

The LELH111-31364-3 circuit breaker works in two main ways. The first is by utilizing an air gap between the terminals of the circuit breaker to prevent an electric arc from forming. The air gap is also used to reduce the effects of electrical sparking. As a result, the circuit breaker provides more reliable protection against damage and electrical fires caused by overloads and short circuits.

The second working mechanism of the LELH111-31364-3 circuit breaker is the use of an actuating element to detect and trip the circuit breaker. The actuating element is typically a bimetal thermostat that is placed in contact with the terminals of the circuit breaker. It is designed to detect an increase in electrical current and will trip the circuit breaker when the current exceeds a certain threshold. This helps to protect electrical appliances from damage caused by short circuits and overloads.

Overall, the LELH111-31364-3 circuit breaker is an ideal device for providing protection against overloads and short circuits. With its ability to monitor overvoltage and its air gap mechanism for preventing sparking, it is able to provide reliable and effective protection of electrical components.
