Product Description
Our MNS type low-voltage withdrawable switchgear, a pinnacle of electrical engineering, is meticulously refined from ABB's renowned MNS series low-voltage switchgear from Switzerland. Embodying the forefront of technological advancement in China, this switchgear is constructed from standardized, modular components. The drawers incorporate robust mechanical interlocks, ensuring unparalleled safety and reliability for users.
This versatile switch cabinet is designed for AC 50 (60) Hz, with a rated working voltage of 400V to 660V and a rated current of up to 5000A. It's perfectly suited for deployment across a wide spectrum of environments including power plants, substations, industrial and mining facilities, as well as commercial buildings like hotels and airports. Its capabilities extend to power generation, transmission, distribution, and consumption control, including reactive power compensation via a capacitance compensation cabinet. Our product adheres strictly to national standard GB7251.1 'low-voltage switchgear' and international standard IEC60439 'low-voltage switchgear and control equipment'.
Use Environment
1. The ambient air temperature should not exceed +40°C nor drop below -5°C, with the average 24-hour temperature staying within +35°C.
2. It is designed to function optimally at relative humidity levels that do not exceed 50% at a maximum temperature of +40°C. Higher humidity levels are permissible at reduced temperatures, up to 90% at +20°C, accounting for potential moderate condensation due to temperature fluctuations.
3. Intended for indoor installation, ensuring the installation height does not surpass 2000m above sea level.
4. Installation should be in locations free from severe vibration and impact, and where electrical components are shielded from corrosive substances.
