Circuit breakers are essential components of electrical systems worldwide. They are responsible for protecting the electrical equipment from superimposed currents and preventing damage from overloading. The R21-4-15.0A-9191-2-V is an example of a circuit breaker which is designed for application in low voltage distribution networks. It is composed of an insulated case, steel frame and semiconductor device.

The insulated case is fitted with a plastic enclosure which prevents contact with live parts and allows for installation of the whole unit into electrical systems. Inside the insulated case, there is the steel frame which provides protection against mechanical loads. According to the manufacturer specifications, R21-4-15.0A-9191-2-V is able to withstand a mechanical load of fifteen thousand amps. A semiconductor device is located inside the steel frame. This device is designed to detect any current overload and trips the circuit breaker in case of an emergency.

R21-4-15.0A-9191-2-V has several application fields. It can be used in residential, commercial and industrial settings. It is especially recommended for use in high voltage distribution networks where extremely powerful currents might be present. Additionally, it can also be used in solar power generation systems to protect the electrical components from unexpected overloading.

The working principle of the R21-4-15.0A-9191-2-V is quite simple. When there is an overload, the semiconductor device detects it and triggers a series of events which ultimately cause the circuit breaker to trip. At this point, the circuit breaker cuts off the flow of electricity, thus avoiding any further damage to the electrical system.

In conclusion, the R21-4-15.0A-9191-2-V is an excellent example of a circuit breaker which is designed for use in low voltage distribution networks. It is constructed with an insulated case, steel frame and semiconductor device. It can be used in residential, commercial, and industrial settings and is very suitable for use in solar power generation systems. The working principle of the R21-4-15.0A-9191-2-V is such that when the semiconductor device detects an overload, it trips the circuit breaker and thus prevents any further damage to the electrical system.
