What is a magnetic circuit breaker?
The magnetic circuit switch is a safety device designed to cut electric current in case of power surge, thus protecting electrical equipment and circuits from damage. Overloaded circuits, free or defective wiring and lightning can cause a magnetic circuit breaker. During an increase or short circuit, there are other devices that are able to break the circuit of which each has its own limitation. The fuses have a thread that burns during the growth, which means that they will not work after blowing and must be replaced immediately to restore energy. Other commonly available circuit breakers are sensitive to heat and require cooling periods after overvoltage, but the magnetic circuit breaker can be reset immediately and restores energy without delay. Some circuit breakers rely primarily on temperature and trip when overheating, but the magnetic circuit breaker uses an electroomagnet or solenoid to generate a magnetic field that is used to measure current strength. When the power of electric current increases, it increasesAlso magnetic field of solenoid. This field pulls to the metal lever in the circuit breaker. This lever is held on the site of spring and under normal conditions the magnetic field is not strong enough to move the lever.
The magnetic circuit breaker has an evaluation, a preset limit to the maximum power strength that allows it to flow. When the current exceeds the circuit breaker limit, the solenoid magnetic field increases to a point where it is strong enough to move the lever. Circuit trips, contact points are far away and the perimeter is interrupted before it can be damaged. No current flows through the perimeter, so the solenoid also loses strength and also loses magnetic loss. This means that the circuit breaker can be reset immediately.
Although the magnetic circuit breaker is excellent for solving spikes from short circuits and large energy overvoltage, the energy remains continuous if the increase does not exceed the circuit breaker limit. DloLow -level increases may cause overheating of the device and circuits, which potentially causes damage to the device or causes fire. The thermal magnetic circuit breaker solves this danger using a pair of metal strips that cause the circuit breaker to stumble if it is overheated. In many areas of the world, residential panels primarily use thermal magnetic circuit breakers.
