Circuit breakers are the most important safety features for electrical systems, designed to protect both the equipment and people throughout the duration of the electrical circuit. While their purpose is simple, the technology behind them is complex and highly nuanced. The BA2-B0-34-615-121-D is one such circuit breaker, designed for a specific application field. As a result, it has precise working principles and specifications that must be considered depending on the desired application.

Application Field

The BA2-B0-34-615-121-D is a type of low-voltage miniature circuit breaker. As a type of MCB, this circuit breaker is primarily used in smaller-scale electrical installations, such as in residential and light commercial buildings. It is also used in medium-sized air-conditioning systems, and as a motor protector in machines. This circuit breaker has a “Smart” version that is used as a main switch in solar panel systems. It is rated for a voltage of 230/400V AC and currents up to 63A. It requires a spare part mount of type P15, P17 and MT DIN-rail. Due to its versatility and flexibility, the BA2-B0-34-615-121-D is a popular choice for a variety of different applications.

Working Principle

The BA2-B0-34-615-121-D is a solid state manually operated switch, with a reset feature or a “trip”. As its name implies, miniature circuit breakers work under the principle of over-current protection. When the current being delivered through the circuit exceeds the set threshold, it triggers the circuit breaker’s trip mechanism. This causes the circuit to be interrupted by opening the breaker’s contacts, cutting off the current flow. The circuit breaker can then be manually reset to restore the circuit. This resetting can only be done after the problem that caused the over-current has been identified and rectified.

Safety Features

The BA2-B0-34-615-121-D is equipped with several additional safety features. The circuit breaker is also equipped with a unique Arc Fault Detection Device (AFDD). This device monitors and records the arc’s current and fault characteristics, and if an abnormality is identified, will trip the circuit breaker automatically and safely to prevent any damage or fire from further progressing. It also has an under voltage protection device, which is designed to detect any sudden significant drops in the circuit’s voltage, and trips the circuit when necessary to avoid any damage.

Conclusion

The BA2-B0-34-615-121-D is a type of miniature circuit breaker, primarily intended for residential and light commercial applications where low power is used. It has a number of unique features such as Arc Fault Detection and Under Voltage protection, making it a reliable tool for arc fault, overload, and short-circuit protection. With its convenience, durability, and multiple safety features, the BA2-B0-34-615-121-D is an invaluable tool for electrical applications.
