9120353200 Datasheet/PDFCircuit Breakers
9120353200 application field and working principle are related to circuit breakers. Circuit breakers are used in many types of electrical and electronic circuits. They are used to prevent voltage and current overloads, as well as to protect against short circuits. Circuit breakers work by automatically opening and closing electrical circuits, depending on the level of current or voltage being applied to them. Circuit breakers are used in a variety of applications, including residential, commercial, industrial, and medical.
In the residential application, circuit breakers are used to provide protection from electrical overloads and electric shock. They are commonly installed in homes and apartments to prevent overloading of circuits and protect against short circuits. In commercial applications, circuit breakers are used to protect electrical motors, light bulbs, and other electrical components. Industrial circuit breakers are used to protect machinery and electrical equipment from overloads and short circuits.
Circuit breakers are typically rated for a rated voltage, maximum current-carrying capacity, and maximum short-circuit current. Their rated voltage is the maximum voltage they can withstand before they trip. The maximum current-carrying capacity is the maximum current that the circuit breaker can handle without tripping. The short-circuit current is the maximum current that the circuit breaker can handle before it trips. Depending on the application, circuit breakers may be equipped with additional features such as thermal overload protection, which will trip the breaker if the temperature of the circuit exceeds a certain level.
When a current flows through a circuit breaker, an electromagnet is activated. The electromagnet is connected to a trip coil, which in turn is connected to the trip lever in the circuit breaker. When the current exceeds the rated value, the electromagnet is strong enough to quickly move the trip lever from its open position to its closed position, thereby interrupting the flow of current. The circuit breaker then remains in the tripped state until the current is lowered to the rated value and the trip lever is able to move to the open position.
The working principle of a circuit breaker is relatively simple. The current is measured by a temperature-sensitive bimetallic strip, which is connected to the electromagnet. The bimetal strip will heat up when a higher current is applied to the circuit breaker. This heat then causes the bimetal strip to bend, thereby activating the electromagnet and causing the trip lever to close. This process will interrupt the flow of current through the circuit and protect it from overloads and short circuits.
In conclusion, 9120353200 application field and working principle relate to circuit breakers. Circuit breakers are used in residential, commercial, industrial, and medical applications to prevent voltage and current overloads and short circuits. The working principle of a circuit breaker is fairly simple and involves a temperature-sensitive bimetallic strip, an electromagnet, and a trip lever.
