229D-2-33355-78 Circuit Protection

Circuit breakers are safety mechanisms that protect electrical circuits and equipment from excessive load currents. They are essential components in any electrical system, since they protect circuits and equipment from overloads that could cause fires or other damages. The 229D-2-33355-78 circuit breaker is a mainly used in the electronic and electrical industry.

Application field:

The 229D-2-33355-78 circuit breaker is mainly used in electronic and electrical industries, such as home appliances, audio-visual equipment and automotive electronics. It is specially designed for low voltage applications such as AC mains and DC supplies. The breaker’s capabilities include overvoltage protection and overcurrent protection. Its compact size makes it suitable for applications with limited space and weight constraints, such as electric vehicles, battery packs, and small solar systems.

Working principle:

The 229D-2-33355-78 circuit breaker uses a snap-action mechanism to trigger the overload protection. This mechanism senses current flow within the breaker and quickly trips a contact to open the circuit when an overload is detected. When the overload is removed, the contact will reset and close the circuit again. The 229D-2-33355-78 also features a manual reset button that can be used to reset the circuit breaker when needed.

The 229D-2-33355-78 contains a current transformer (CT) which helps to detect the magnitude of current that is flowing through the system. The CT senses the current level and, when the current level exceeds a certain threshold, it triggers the circuit breaker’s overload protection. The 229D-2-33355-78 also features a voltage sensing circuit that can detect when the voltage in the system is over a certain limit.

In addition, the 229D-2-33355-78 circuit breaker features temperature sensors that can detect if the temperature of the system is too high. If the temperature goes over the limit, the breaker will trip to prevent the system from overheating. This helps to protect not only the system, but also the users of the system, from potential damage.

The 229D-2-33355-78 circuit breaker is used to protect electrical systems from damage due to overloads. Its snap-action mechanism quickly triggers the protection when an overload is detected, and it also contains temperature sensors to protect the system from overheating. The CT and voltage sensing circuit help to accurately identify when the system is experiencing an overload. The 229D-2-33355-78 is a reliable and effective circuit breaker that is used in many electronic and electrical applications.
