Circuit Breakers

219-3-28531-1-V circuit breaker is a common type of circuit breaker, mainly used for small and medium-sized power systems such as domestic appliances and lighting. It is mainly used to protect people from power outages, overloads, short circuits and other faulty operations. It is a type of overcurrent protection device, which detects the overload or short circuit situation, and when the current of the circuit reaches a certain value, it trips the circuit breaker.

Application Field

The 219-3-28531-1-V circuit breaker can be used for many kinds of circuits in households, such as air conditioners, refrigerators, water heaters, ovens, washing machines, computers, telephones, fans, lighting and other home appliances. It can also be used in industrial applications such as factories, mines, laboratories, airports, hospitals, elevators, etc.

Working principle

The working principle of the 219-3-28531-1-V circuit breaker is based on the current monitoring principle of the electromagnetic induction device. It consists of a reactor, a coil, an armature, a movable contact and an overcurrent tripping device. When the circuit current exceeds the set value, the magnetic field generated by the reactor induces an electric exhaust force on the armature, and thus the armature moves to the side of the other stationary contact, thus tripping the circuit breaker. At the same time, the arc extinguishing chamber consumes some energy, and the arc of the power supply will be extinguished due to the lack of energy, achieving the purpose of protecting the power supply.

Conclusion

In summary, the 219-3-28531-1-V circuit breaker is a type of overcurrent protection device, which can effectively protect users from overcurrent, overload, short circuit and other faults. It can also be used in various home entertainment and industrial application fields. Its working principle mainly relies on the electromagnetic induction of the permanent magnet to detect the overload or short circuit situation, and then the armature cuts off the power supply to protect the power distribution line.
