1140-G151-P7M1-7A application field and working principle

Circuit breakers are an important part of a modern electrical system. They are designed to protect the electrical equipment and the apparatus from potential damage caused by overcurrents, and to protect the safety of persons working in the area. The 1140-G151-P7M1-7A circuit breaker is a low voltage air circuit breaker.

Application Field

The 1140-G151-P7M1-7A circuit breaker is ideally suited for protection of low voltage electrical circuits with rated currents from three amperes to 80 amperes. This circuit breaker is suitable for use in factories, industries, mines and other places where medium-sized electrical appliances occupy a large proportion of the electrical system.

Working Principle

The 1140-G151-P7M1-7A circuit breaker basically works by the sense of overcurrent. When the load current of the circuit is greater than the rated current, the circuit breaker will trip, thus quickly disconnecting the circuit, protecting it from being damaged.

The 1140-G151-P7M1-7A circuit breaker is equipped with manual/shuttle, that is, an power disconnect switch. When the switch is in the open position, the circuit breaker is disconnected from the power supply; when the switch is in the closed position, the circuit breaker is connected to the power supply.

In addition, the 1140-G151-P7M1-7A circuit breaker also has a thermal-magnetic protection that prevents the circuit from overheating or current surges. It also has an indicator to show the status of the circuit breaker for easy maintenance.

The 1140-G151-P7M1-7A circuit breaker is designed with a wide range of features and a high level of safety, making it an ideal choice for various industrial and commercial applications.
