The 3120-F323-P7T1-W19FG2-15A circuit breaker is one of the most commonly used devices in electrical systems. It is used to protect electrical circuits from damage due to over-currents, overheating and short circuits. This type of breaker is an automatic switch, which is triggered in the presence of an excessive current. It performs two functions at the same time: preventing over-currents and providing protection against damages due to incorrect wiring. In this way, it provides enhanced safety from electrical hazards.

Application Field

This type of circuit breaker is widely application in industrial, commercial and residential electrical circuits. It is commonly used in large motor control systems and other electrical equipment such as air-conditioners, refrigerators, and washing machines. It is also used in commercial and residential applications, such as in protection of household or industrial appliances.

Working Principle

The operating principle of the 3120-F323-P7T1-W19FG2-15A circuit breaker is based on the concept of differential current. During normal operation, the current flowing through the circuit is the same as the current entering the circuit. When an overload occurs, the current flowing through the circuit increases and the current entering the circuit decreases. This difference in current activates the trip mechanism of the breaker which causes the circuit to be cut off. The trip mechanism is set to trip the breaker at different levels of over-current, depending on the rating of the breaker.

The breaker is designed with an adjustable over-current threshold which allows for precise adjustment of the current levels at which the breaker will be triggered. This is especially important for large systems as the breaker must be able to trip consistently at the specified current levels. This is why a 3120-F323-P7T1-W19FG2-15A circuit breaker is used in applications where precise settings are required.

The 3120-F323-P7T1-W19FG2-15A circuit breaker is also designed with a thermal overload protection. This feature prevents the over-current situation from getting worse by tripping the breaker before reaching the preset over-current threshold. When the current flowing through the circuit is high enough to cause the thermal protector to trip, the breaker trips and breaks the connection. This ensures the system is protected from any potential damages caused by a severe over-current situation.

The 3120-F323-P7T1-W19FG2-15A circuit breaker is a reliable and efficient device for protecting electrical circuits from over-current, overheating and short-circuits. It is widely application in industrial, commercial, and residential systems and can be easily adjusted to meet the requirements of different applications. It is an essential device for ensuring the safety and proper functioning of electrical systems.
