MNS Series Low-Voltage Switchgear For Industrial and Mining Enterprises
MNS Low-Voltage Withdrawable Switchgear
The MNS low-voltage withdrawable switchgear (referred to as the switchgear) consists of a power center (PC) and a motor control center (MCC). It is suitable for power control and distribution systems operating at 50Hz-60Hz AC and rated operating voltages of 660V and below. It is widely used in power plants, substations, industrial and mining enterprises, and other power users for power distribution, motor control, and lighting equipment, including power conversion, distribution, and control.

This device is suitable for transportation and storage within the following temperature range: -25°C to 45°C, with temperatures reaching 70°C for short periods (no more than 24 hours). The device should not suffer any irreversible damage at these extreme temperatures and should function normally under normal conditions. Any failure to meet these operating conditions should be resolved through consultation between the user and the manufacturer. A separate technical agreement must be signed for the use of this device in offshore oil and nuclear power plants.
III. Main Features
The cabinet frame features a C-section modular structure, with all structural components galvanized or coated with aluminum-zinc sheet metal.
The drawer units utilize high-strength, flame-retardant engineering plastic components, effectively enhancing safety and protection.
The drawer units are compact, highly functional, highly interchangeable, easily replaceable and maintainable, and offer reliable contact.
The cabinets feature side or rear wiring options, and the vertical channels utilize half-panel panels for ease of maintenance and reduced costs.
