Circuit breakers are essential components in any electrical system as they act as an intermediary between the power source and the electrical system, and provide protection against potential faults or overloads.219-3-38382-1-V is one such type of circuit breaker, used in high voltage applications. It is designed to disconnect the load in the event of a fault or an overload, and to protect the load from any potential electrical hazard.

The main application of the 219-3-38382-1-V circuit breaker is in medium voltage applications, specifically 3.3kV. This particular type is suitable for use in a wide range of industrial, commercial and residential applications, such as transformers, motor drives, generators, lighting, and HVAC applications.

The working principle of the 219-3-38382-1-V circuit breaker is relatively straightforward. When the current passing through the circuit exceeds the rated value, the device will automatically switch off the power supply, protecting both the load and the power source from damage. This is done by an internal mechanism known as the thermal-magnetic tripping system, which consists of a thermal element and a magnetic element. The thermal element is activated when the current reaches a certain limit, and it reacts by activating the magnetic element.

The magnetic element then creates a force that forces the internal contacts of the breaker apart, thus interrupting the current flow. This interruption of the current ensures that the fault or overload is stopped immediately, and that the power supply to the load is switched off in order to protect the equipment from further damage. Additionally, the 219-3-38382-1-V is designed with a manual reset switch in case a restart is necessary.

In addition to its primary function of protecting against faults and overloads, the 219-3-38382-1-V circuit breaker is also designed with other features such as current monitoring and protection against short-circuiting, making it ideal for use in a wide range of applications. It is also equipped with a test switch, allowing for an on-site test of its functionality.

The 219-3-38382-1-V circuit breaker is a reliable and versatile device that offers reliable protection for both the power source and the load. Its wide range of applications and features make it suitable for a variety of industrial, commercial, and residential applications.
