Introduction of Circuit Breakers

Circuit breakers are a type of electrical device designed to protect against electrical overloads and short circuits. They are classified as either AC or DC, depending on the type of current used. In general, a circuit breaker will open when a certain amount of current is exceeded, allowing the current to be rerouted safely into another circuit, or allowing the circuit to shut down.They can be further divided into different application fields, such as residential, commercial, industrial and distribution, each of which requires specific features from the breaker. Typical features include thermal-magnetic protection, adjustable trip settings, current sensing, and other advanced features.

4120-G217-J3M1-S8S0ZA-1A application field and working principle

The 4120-G217-J3M1-S8S0ZA-1A circuit breaker is an industrial-grade breaker designed for commercial applications. It is a dual-trip, adjustable-trip unit that offers protection against both overloads and short circuits. This breaker is also equipped with an in-built test device to ensure that it is working correctly, and to prevent it from tripping unnecessarily.The working principle of this breaker is based on thermal-magnetic protection. When a circuit is overloaded, the current will produce heat, which will then cause the system to trip the breaker. The thermal-magnetic protection will also cause the system to trip the breaker if the current reaches an unsafe level, regardless of whether the current is too low or too high.The breaker has adjustable trip settings that allow the user to set the breakers to trip at different levels of amperage. The breakers can be easily and quickly reset, even after they have tripped due to an overload or a short circuit.

Conclusion

The 4120-G217-J3M1-S8S0ZA-1A circuit breaker is an industrial-grade breaker designed for commercial applications, offering both overload and short circuit protection. It is equipped with a test device to ensure it is working correctly, and it has adjustable trip settings for user convenience. The breaker is based on a thermal-magnetic protection system, which will trip the breaker if the current is unsafe. The breakers can be reset easily, even after they have tripped due to an overload or a short circuit.
