Product Description
Our MNS type low-voltage withdrawable switchgear represents the pinnacle of technological advancement in China. Crafted meticulously with insights from ABB's Swiss MNS series, our switchgear is a testament to engineering excellence. It is built from a series of standardized modules, offering mechanical interlocks that enhance both safety and reliability for our valued users.
This versatile switch cabinet is engineered for AC 50 (60) Hz systems with rated voltages of 400V or 660V, and current ratings up to 5000A. It seamlessly fits into three-phase five-wire power systems, suitable for diverse environments like power plants, substations, industrial settings, commercial buildings, hotels, airports, docks, and communication centers. It excels in power generation, transmission, distribution, conversion, and consumption control, and offers reactive power compensation via capacitance compensation cabinets. Adhering to rigorous standards, it complies with GB7251.1 and IEC60439, ensuring premium quality and reliability.
Use Environment
1. The optimal operating temperature range for the ambient air spans from -5 °C to +40 °C, with an average not exceeding +35 °C over a 24-hour period.
2. At a maximum temperature of +40°C, surrounding air's relative humidity should not surpass 50%. A higher relative humidity is permissible at lower temperatures, for instance, it can reach 90% at +20°C. Be mindful that occasional moderate condensation may occur with temperature shifts.
3. Designed exclusively for indoor use, it is effective at altitudes up to 2000m without compromising performance.
4. Installation should be in areas free from severe vibrations and impacts, ensuring electrical components remain uncorroded and operational.
