Circuit Breakers

Circuit breakers are an essential part of modern electrical protection systems. They are designed to protect an electrical circuit from damage due to overcurrent or short circuit conditions. The 2210-S221-P1M1-H0-25A circuit breaker is an important addition to the family of circuit breakers currently available. This article will discuss the application field and working principle of the 2210-S221-P1M1-H0-25A circuit breaker.

Application Field

The 2210-S221-P1M1-H0-25A circuit breaker is suitable for use in industrial and commercial electric systems with an AC working frequency of 50 or 60 Hz, rated voltage of up to 440V and rated current of up to 25A. It is particularly useful when space is limited or there is a need to reduce operational costs. This circuit breaker is safe and reliable to use, and its switching characteristics are excellent. It can effectively protect circuits and the electrical equipment connected to them from overload, short circuit and ground fault.

Working Principle

The 2210-S221-P1M1-H0-25A circuit breaker uses an electromagnetic actuator to detect and control overcurrent and fault conditions. When overcurrent or fault conditions are present, the circuit breaker trips its contacts open and de-energizes the circuit. The exact operation of the circuit breaker depends on the type of actuator used in the device. The most common type of actuator is electromagnet, which uses a coil to generate a magnetic field that trips the circuit breaker open when certain current thresholds are exceeded. This electromagnetic actuator is usually connected to the circuit breaker through a system of levers and cables to provide additional control of the tripping action.

The 2210-S221-P1M1-H0-25A circuit breaker also contains a thermal element, which acts as a backup protection and trips the circuit breaker if the current exceeds certain pre-defined limits for an extended period of time. The thermal element achieves this by increasing its resistance with increasing temperature, which deactivates the circuit breaker and trips its contacts open. This ensures that the circuit is not overloaded and that the electrical equipment connected to it is always protected.

Conclusion

The 2210-S221-P1M1-H0-25A circuit breaker is a reliable and efficient device for providing protection to electrical systems. Its use is well suited for industrial applications, as it offers excellent performance and dependable safety even when space is limited. The circuit breaker uses an electromagnetic actuator and a thermal element to detect and control overcurrent and fault conditions. As such, it effectively protects circuits and the electrical equipment connected to them from overloading, short circuits, and ground faults.
