The DA2-B0-34-610-121-C is a type of circuit breaker, a device used to interrupt an electrical circuit in order to protect it from damage due to fault currents. It is a three-pole, molded-case breaker, specifically designed for use in parts of the electrical distribution system where a high level of fault protection is required. The breaker is also equipped with an adjustable thermal-magnetic trip and a manual bypass switch, which allows the breaker to be placed in either an on or off position.

Circuit breakers are typically used in a wide range of applications, from residential and industrial power distribution systems to the largest electric power utilities. In residential applications, circuit breakers are used to protect individual electical circuits from being overloaded by large electrical currents. In industrial settings, they are used to protect machines and equipment from overvoltage or short-circuiting. And in power distribution systems, they are used to prevent overloading of the system from fault currents.

The working principle of circuit breakers is based on the control of the flow of current through an electrical circuit. Circuit breakers are designed to detect any type of excessive current that could cause damage to electrical components and appliances. When a fault current of a certain magnitude is detected in the circuit, the circuit breaker trips, interrupting the circuit and preventing further damage.

The DA2-B0-34-610-121-C is specifically designed for the protection of medium voltage power systems, such as power distribution lines, transformers, and other high-power electrical components. It is also suitable for applications where fast response and interruption of currents up to 20 kA are required. The breaker has an adjustable trip setting and manual bypass switch that allows the breaker to be placed either in an on or off position.

The DA2-B0-34-610-121-C is an example of a reliable, efficient circuit breaker designed to help protect systems and components from overloading, short-circuiting, and other faults. It is highly sensitive to fault currents and is able to trip in less than 150 milliseconds when overloaded, providing protection for electrical components and appliances against high currents that could cause serious damage.
