Circuit breakers are an essential component of any electrical system. They are responsible for providing an overload protection by automatically disconnecting the electrical circuit when it is subject to an excessive current. The 1140-G151-P7M1-5A circuit breaker is a three-pole type that can be used in a variety of applications. This article will provide a detailed overview of the 1140-G151-P7M1-5A application field and working principle.

Application Field

The 1140-G151-P7M1-5A circuit breaker is designed for applications up to 250 volts. It is suitable for air conditioning equipment, lighting and electric motor circuits, as well as for residential and industrial control systems. The circuit breaker can be used to protect circuits of a single family house, as well as of an entire industrial complex. The circuit breaker is designed for operation and protection from overloads, short circuits and high fault currents, as well as for protection against other hazards and abnormal conditions.

Working Principle

The 1140-G151-P7M1-5A circuit breaker is based on the magnetic principle of operation. The breaker is equipped with a solenoid that acts as the switch. When a circuit is subjected to an excessive current, the solenoid releases a powerful magnetic field that causes the contacts on the circuit breaker to open, thus disconnecting the circuit. This process takes place on a millisecond time scale and prevents any damage to the electrical system. When the current returns to normal, the circuit breaker will automatically reset and reconnect the circuit.

The 1140-G151-P7M1-5A circuit breaker is equipped with an auxiliary switch that can be used to control a load, such as a motor or lighting. The auxiliary switch is controlled by a latch and can be used to turn a load on or off, regardless of the state of the main circuit breaker. This type of circuit breaker is also equipped with a trip indicator that indicates when the breaker has been activated, allowing quick and easy troubleshooting.

In addition to the magnetic operating principle, the 1140-G151-P7M1-5A circuit breaker is also equipped with thermal protection. This type of protection is designed to prevent overheating of the circuit from excessive current or other faults. The thermal protection works by continuously monitoring the temperature of the circuit breaker and automatically disconnecting the circuit when the temperature exceeds a certain limit. This ensures that the circuit breaker does not overheat and become damaged.

Conclusion

The 1140-G151-P7M1-5A is a three-pole circuit breaker designed for applications up to 250 volts. It is suitable for air conditioning equipment, lighting and electric motor circuits, as well as for residential and industrial control systems. The 1140-G151-P7M1-5A circuit breaker is based on the magnetic principle of operation, which ensures that the circuit is disconnected in the event of an overload or short circuit. The breaker is also equipped with an auxiliary switch and a trip indicator, as well as thermal protection to prevent overheating of the circuit. This makes the 1140-G151-P7M1-5A a reliable and versatile choice for circuit protection in any application.
