The Indoor Vacuum Circuit Breaker is designed to offer reliable and efficient protection for electrical systems in a variety of industrial and commercial settings. This device is particularly well-suited for environments where high performance, durability, and safety are critical. The Indoor Vacuum Circuit Breaker is ideal for use in low and medium voltage electrical distribution networks, ensuring the secure operation of electrical equipment and preventing potential hazards caused by short circuits and overloads.
Key Technical Parameters:
The Indoor Vacuum Circuit Breaker is available in different configurations to meet various power requirements. It operates at a rated frequency of 50Hz and is offered in two current ratings: 630A and 1250A. The rated short time withstand current is either 20kA or 25kA, while the rated peak withstand current can handle up to 50kA or 63kA, depending on the model. Additionally, it has a short-duration rating of 4 seconds, allowing for quick response during fault conditions.
The device also features a rated short circuit closing current of 50kA or 63kA, ensuring that it can close effectively during a short circuit event without causing damage. With a mechanical operating life of up to 10,000 cycles, the Indoor Vacuum Circuit Breaker offers long-lasting performance and reliability.
Usage Conditions:
The Indoor Vacuum Circuit Breaker is designed to operate under a wide range of environmental conditions, making it suitable for various indoor applications. It can function effectively at altitudes of up to 2000 meters and in locations where earthquake intensity does not exceed 8 degrees. The operating temperature range for the Indoor Vacuum Circuit Breaker is between -30°C and 40°C, which allows it to be used in both colder and warmer climates.
In terms of humidity, the Indoor Vacuum Circuit Breaker is designed to withstand daily average relative humidity levels up to 95%, and monthly averages not exceeding 90%. However, it is important to note that this circuit breaker is not suitable for installation in environments with frequent severe vibrations, high moisture, corrosive gases, or high levels of dust, dirt, and salt spray. It should also be kept away from areas with fire and explosion hazards, as these conditions could affect its performance and reliability.
