Circuit Breakers: 3120-F323-P7T1-W19LG4-15A Application Field and Working Principle

A circuit breaker is an electrical device used to protect the electrical circuit from overloads and short circuits. It works by breaking the current path between the source and load when the current exceeds the set limit. In other words, it is a switch that can be manually turned off or remotely operated. The 3120-F323-P7T1-W19LG4-15A is a circuit breaker with a specific application field and working principle.

Application Field

The 3120-F323-P7T1-W19LG4-15A is a DIN rail-mounted type circuit breaker, which can be used for circuit protection for various applications including AC mains, industrial and commercial equipment, motor and generator circuits, electrical installations, AC drives and other electrical loads. It is also suitable for the maintenance and repair of the electrical systems.

Working Principle

The 3120-F323-P7T1-W19LG4-15A operates through the concept of current limitation. When the current in the circuit exceeds the pre-set limit, it trips and the circuit breaker opens to protect the circuit from any further overloads and short circuits. The trip level of the circuit breaker can be adjusted according to the specific requirements by using the settings on the internal selector switch. When a fault condition occurs, the circuit breaker trips and the current flow is stopped instantly.

Features and Benefits

The 3120-F323-P7T1-W19LG4-15A has a number of features and benefits. It has a small, compact size, making it suitable for use in confined spaces. The circuit breaker is easy to install and operate, as it comes with an intuitive user interface. It has an adjustable trip level setting and is also rated for short circuit current up to 25kA. It has thermal and magnetic protection, in addition to illumination and a visible trip indicator, which allows users to identify the failure easily. The circuit breaker also includes a delayed tripping function which helps to minimize nuisance tripping.

Conclusion

The 3120-F323-P7T1-W19LG4-15A is a DIN rail-mounted type circuit breaker for circuit protection for various applications. It is easy to install and operate, and offers thermal and magnetic protection, an adjustable trip level, a visible trip indicator, and a delayed tripping function. This circuit breaker is an ideal choice for electrical systems in industrial and commercial settings.
