Product overview
The MNS type low-voltage withdrawable switchgear (hereinafter referred to as the switchgear) was developed by our company after referring to the MNS series low-voltage switchgear of the Swiss ABB company and making comprehensive improvements. It is currently the most advanced low-voltage withdrawable switchgear in the country. This product is composed of standardized and series modules, and the drawers have reliable mechanical interlocking devices, making them safer and more reliable for users to use.
This switch cabinet is suitable for three-phase five-wire power supply systems with AC 50 (60) Hz, rated operating voltage 400V, 660V, and rated current 5000A and below. It can be used in power plants, substations, industrial and mining enterprises, building hotels, and airports. , docks, radio and television and other communication centers to control power generation, transmission and distribution, power conversion and power consumption equipment, and reactive power compensation is performed on its main bus through the capacitor compensation cabinet.
This product complies with the requirements of GB7251.12-2013 "Low-voltage complete switchgear and control equipment", IEC61439-2:2011 "Low-voltage complete switchgear and control equipment" and other standards.
Model and features
Normal service conditionsNormal service conditions
● The altitude does not exceed 2500m (with special technology, it can reach 4000m);
● The relative humidity of the surrounding air does not exceed 50% when the maximum temperature is +40°C. It has a higher relative humidity at lower temperatures, such as 90% at +20°C, but considering that it may be possible due to temperature changes Moderate condensation may occasionally occur.
● Should be installed in a place where there is no severe vibration or impact, and where electrical components are not subject to corrosion.
Note: When the above normal usage conditions are exceeded, the user can negotiate with the manufacturer to determine.Technical parameter

Structure and DimensionsStructure and Dimensions
The MNS series switch cabinet is installed vertically, not against the wall. Behind it is the outlet cable trench of the cabinet. To facilitate maintenance, the distance from the back to the wall is usually 800~1200mm. For installation from the front, see the figure below.
