Circuit Breakers

A circuit breaker (CB) is a device used to protect an electrical circuit. It is designed to detect an overload or short circuit and protect the circuit from damage due to excess current. circuit breakers are typically used in devices like electric ovens, washing machines, refrigerators, and electric water heaters. The 3120-F321-P7T1-W19DG4-15A circuit breaker is intended for industrial application.

Application Field

The 3120-F321-P7T1-W19DG4-15A circuit breaker can be used for general purpose overload protection in any industrial setting. This circuit breaker is suitable for motor loads and transformer applications. It has an adjustable trip unit that can be adjusted from 0.60 to 1.30 times the rated operational current to accommodate any specific application otherwise. It is designed for general purpose use such as lighting, heating, air conditioning, refrigeration, and machine tool protection.

Working Principle

The working principle of the 3120-F321-P7T1-W19DG4-15A circuit breaker is relatively simple. It works by providing a low-resistance path to ground when the current in a circuit becomes too large, which causes current to flow through the breaker wiring and into the ground, thus preventing damage to other components of the circuit. This low-resistance path is created through the use of a semiconductor, which works as a current-limiting device. The current-limiting device creates a low-resistance path to ground when the current exceeds the breaker trip setting. Once the current passes through the low-resistance path, the current will decrease to a safe level, allowing the breaker to reset.

The 3120-F321-P7T1-W19DG4-15A circuit breaker is designed to operate quickly and efficiently in the event of an overload or short circuit. It is designed to detect the current and initiate the trip action in milliseconds. This reduces the chances of damage to the equipment and wiring, as well as to any users who may be nearby. Additionally, the trip action is designed to be adjustable depending on the needs of the application. This feature makes it easier to customize the breaker settings to accommodate specific current levels, as well as aiding in troubleshooting.

Conclusion

The 3120-F321-P7T1-W19DG4-15A circuit breaker is an excellent choice for general purpose overload protection in any industrial setting. Its adjustable trip unit and current-limiting device allow it to quickly detect any over current situation and protect the circuit from damage. In addition, it is designed to be adjustable to meet the needs of any specific application, making it a versatile and reliable choice for almost any industrial application.
