A circuit breaker is an essential safety device in the electrical industry. Manufactured with the purpose of protection in mind, circuit breakers are designed to detect an excessive current flow, interruption or short circuit, and then open the circuit as a safety measure, isolating the circuit’s power source from the devices and individuals connected to it. The 8345-C01A-U3K1-DB1B4B-X8345-S01HW102M-20A circuit breaker is no different. This circuit breaker’s application field and working principle must be understood in order for it to be properly utilized.

The 8345-C01A-U3K1-DB1B4B-X8345-S01HW102M-20A circuit breaker is specifically designed for individuals needing to protect their electrical circuits from possible damage due to over-currents. The circuit breaker is used in low voltage installations rated at or below 600 volts and provides a safe, efficient way to protect electrical equipment from damage due to short circuit or overloads. Additionally, depending on the application, the circuit can be connected to a manual reset, meaning that, when the circuit breaker trips, a person needs to reactivate it, or it can be reset automatically, meaning it reactivates after it has cooled down for a specified time.

In order to properly understand the application field and working principle of this circuit breaker, it is important to understand how the overload and short circuit current protection systems operate. Overload and short circuit current protection are both important parts of the circuit breaker’s operation and are usually set forth in the technical specifications.

The Overload protection system typically uses current transformers, protection relays and circuit breakers to determine the level of current flow. When the current in the protected circuit exceeds the overload protection’s threshold set point, the relay will initiate the closing of the circuit breaker’s contacts to cut off the power to the circuit. In the event of an overload, the circuit breaker will automatically reset once the excessive current is reduced back to an acceptable level.

In contrast to the Overload protection system, the Short Circuit current protection system is much more complex. The system is designed to protect against instances of alternating current through a circuit that exceeds the short circuit current rating. It uses a set of current sensors and protective relays to detect when an abnormally high amount of current begins flowing throughout the circuit. Once detected, the protective relays will send an actuating signal to the circuit breaker, resulting in its trip, interrupting the flow of current through the circuit and protect it from damage.

It is important to note that the application of the 8345-C01A-U3K1-DB1B4B-X8345-S01HW102M-20A circuit breaker in any given situation will depend heavily on the working environment and its specific use case. It is easy to overlook the various parameters that can affect the efficiency and overall performance of the circuit breaker, so an engineer should always adhere to the guidelines set forth in the technical specifications in order to ensure the optimal performance of the system.

Understanding the 8345-C01A-U3K1-DB1B4B-X8345-S01HW102M-20A’s application field and working principle is essential in order to get the most out of the circuit breaker. This understanding, coupled with strict adherence to the technical specifications, will help ensure that the circuit breaker is properly utilized in any given situation, providing maximum protection for all connected electrical systems.
