219-4-6388-048

Circuit breakers, such as the 219-4-6388-048 model, are electrical switches designed to protect an electrical circuit from damage caused by overload or short circuit. When the current passing through the switch reaches a predetermined threshold, the switch is triggered and it quickly cuts off the current, thereby protecting the electrical system.

The usage of the 219-4-6388-048 circuit breaker is quite versatile. This model can be applied to medium and low voltage, both AC (alternating current) and DC (direct current) electrical systems, making it suitable for multiple applications. In addition, this model is also used in industrial settings like substations and power plants, as well as in domestic settings like homes and offices for overload protection.

The working principle of the 219-4-6388-048 circuit breaker is based on the relationship between current and magnetic flux through a coil. When an electrical current passes through the contactor, it creates a magnetic field that causes the moving core to move. This is possible due to the bimetallic strip that is attached to the moving core. When the current reaches the threshold level, the bimetallic strip bends and pushes the creeper, which then triggers the breaker. This causes the mechanical contacts of the switch to open and break the circuit.

The 219-4-6388-048 circuit breaker is equipped with a number of different features which help it operate efficiently and safely. It has adjustable trip current levels which give users the option to choose the breakage current according to their requirements. In addition, it has a reliable contact system in place, as well as over-voltage protections which help to prevent electrical shocks and damages to the electrical system.

The 219-4-6388-048 circuit breaker is a highly efficient device for protecting electrical systems and has many uses. It is a reliable device and can be used to keep an electrical system safe from overload or short circuit. In addition, the adjustable trip current level gives users the option to adjust the breakage current according to their needs. Finally, it has over-voltage protection which helps to prevent electrical shocks and damages to the electrical system.
