DB2-B0-46-620-122-D Application Field and Working Principle

Circuit breakers are used in electrical engineering circuits to provide protection for electrical equipment in the circuit. The DB2-B0-46-620-122-D is a circuit breaker with two poles, and is therefore suitable for utility applications.

Application Fields

The DB2-B0-46-620-122-D is designed to provide an automatic current limiting function, making it ideal for use in a wide range of utility applications, including power systems, distribution systems, and other applications requiring high levels of protection. Additionally, this circuit breaker can be used to protect against short-circuit conditions, such as those caused by power surges, ensuring the safety of both equipment and personnel.

Working Principle

The DB2-B0-46-620-122-D circuit breaker consists of two inverted bells attached to two different circuit arms. These two circuit arms reduce the chance of an electrical arc occurring and the circuits remaining energized when a fault is detected. The contacts are linked together, and when a fault occurs, the electric current flowing through the contact arms triggers a mechanism that causes the circuit breaker to open.

The DB2-B0-46-620-122-D circuit breaker has two levels of current protection, ensuring that both the equipment and the system are safe. The first level of protection is provided by the trip mechanism, which senses the increase in current and causes the circuit breaker to immediately disconnect the circuit. The second level of protection is provided by the reset mechanism, which provides a delayed response to the initial trip in the event of a current overload. The reset mechanism allows the user to reset the circuit breaker after it has opened due to an overload, helping to prevent equipment damage and minimize downtime.

In addition to the trip and reset mechanisms, the DB2-B0-46-620-122-D circuit breaker features an LED indicator that shows the status of the circuit breaker. This LED indicator provides a visual indication of the circuit breaker\'s status, making it easier to diagnose problems and allowing maintenance personnel to quickly recognize any issues in the system.

The DB2-B0-46-620-122-D circuit breaker is designed to provide a reliable and efficient means of protecting systems in a wide range of utility applications. Its combination of current-limiting and short-circuit protection features, along with its LED indicator, make it an ideal choice for many power applications.
