9104153200

Circuit breakers are essential components of virtually all electric power systems for offering robust protection, automated switching operations and fault clearance. 9104153200, known as 6300X frame, is a medium voltage vacuum circuit breaker produced by ABB that has been on the market for more than 40 years. This device is designed to provide protection and control against electric shocks, fires, and other electrical hazards for a wide range of applications.

The 9104153200 consists of a breaker frame, an armature, and a contact assembly. The breaker frame provides the necessary mounting, guidance and bearing of the armature and is typically made of steel. The armature is composed of two spring-loaded plungers located between conductors in the contact assembly that provide a reliable electric contact. The contact assembly includes several contact switching parts, such as isolated contacts, heated contacts, and contact clips.

The 9104153200 can be used in a broad range of applications and configurations, such as air-switching, instrument-switching, transformer switching and hybrid switching. Air-switching is the most common application, used for providing remote operations for circuit breakers in a safe and reliable manner. Instrument-switching is used for switching off small circuits, requiring precise contact opening and closing. Transformers switching allows the user to switch off large electrical loads, such as motor-driven apparatus, transformers, and large electric cables. Hybrid switching is used for both manual and remote operations, allowing users to control and monitor the switching operations from both a local and a remote location.

The 9104153200 works on the principle of vacuum switching. The device relies on a vacuum atmosphere inside its enclosure to provide reliable contact operations. The vacuum atmosphere reduces the amount of electrical arc generated when switching occurs, minimizing the risk of electrical fires. It also provides low contact resistance and efficient contact closing, meaning that less energy is needed to make and break contacts. Furthermore, the vacuum atmosphere provides a high degree of insulation, meaning the device can be used safely in the presence of flammable gases and liquids.

The 9104153200 is also equipped with a protective relay that monitors abnormal conditions of the system. In case of overvoltage, undervoltage, or overcurrent conditions, the protective relay is triggered and the breaker is tripped or disconnected. The protective relay is designed to block the current for a period of time before allowing it to return to its original settings. This ensures that the circuit is not exposed to excessive current, therefore preventing damage to the electrical components.

In conclusion, the 9104153200 is an iconic medium voltage vacuum circuit breaker designed to handle a wide range of applications and configurations. The device works on the principle of vacuum switching and is equipped with a protective relay to monitor abnormal conditions. The vacuum atmosphere within the device helps to minimize the risk of electrical fires and provides a high degree of insulation. The 9104153200 is a reliable and robust device, perfect for a variety of different applications and settings.
