Circuit Breakers

The 4120-G214-J3M1-C4S0ZN-2A circuit breaker is an intelligent, reliable, and advanced circuit protection device with a wide range of applications. This circuit breaker is designed to provide overcurrent protection and is commonly used in industrial facilities, construction sites, and residential buildings. It is suitable for various types of load applications including single-phase, three-phase, and four-wire systems.

Application Field

The 4120-G214-J3M1-C4S0ZN-2A circuit breaker is well-suited for a variety of applications, such as protecting electrical devices connected to the grid from being damaged due to an overcurrent. In industrial production and construction, this circuit breaker can protect motors and machines from overloads and short-circuits, protecting personnel and equipment from the hazards of electric shock or fire. In residential buildings, these circuit breakers can provide protection to large appliances, including air conditioners and refrigerators.

Working Principle

The 4120-G214-J3M1-C4S0ZN-2A circuit breaker is a kind of mechanically-operated protection device. It consists of two parts, namely the insulation chamber and the contact chamber, which are connected to each other. The insulation chamber contains a magnetic circuitry that is connected to a current transformer and a voltage transformer, which measure the system parameters of current, voltage, and current unbalance. The contact chamber consists of a contact switch and a protective device. When the current passing through the circuit breaker exceeds the predetermined value, the contact switch trips and opens the circuit, thus protecting the device from being overloaded.

In addition, the contact chamber also contains a variety of protection features that improve the safety of the circuit breaker. These features include short-circuit protection, overload protection, asymmetric current protection, locked rotor protection, temperature protection, and phase imbalance protection. This feature set provides superior protection performance and is beneficial in protecting against any overcurrent or overvoltage situations.

Conclusion

The 4120-G214-J3M1-C4S0ZN-2A circuit breaker is an intelligent, reliable, and advanced device that provides superior protection in diverse applications. It is designed to provide overcurrent protection and is suitable for both single-phase and three-phase systems. This circuit breaker is suitable for a variety of applications, including industrial production, construction, and residential buildings. It has multiple protection features, which provide optimal safety performance in even the most demanding environments.
