MNS Low Voltage Withdrawable Switchgear

Low - voltage switchgear is applicable to power generation and power supply systems with three - phase AC frequency of 50 - 60Hz, rated operating voltage of 380V (660V) and below, and rated current of 6300A and below. In the low-voltage power distribution systems, MCC (motor control center) and MDB (main distribution board) are two key components, each assuming different functions.

  • Product Introduction

    MNS low-voltage withdrawable switchgear is a combined, modular, standardized, multifunctional low-voltage power distribution cabinet assembled by the factory with standard modules. It is suitable for three-phase four-wire and three-phase five-wire power systems with AC 50-60Hz and rated working voltage of 380V (660V). The maximum rated working current is up to 6300A. It is used as a low-voltage system for power distribution and motor control systems in all places requiring high reliability in power plants, substations, petrochemicals, metallurgy and steel, transportation energy, light industry and textiles, and other factories and mines, residential areas, high-rise buildings, etc.

    Function Configuration

    MCC(Motor Control Center)

    Core functionsCentralized control, protection and monitoring of motors and other power equipment in industrial environments.
    Application scenariosWidely used in factory production lines, pump stations, fan systems and other occasions where multiple motors need to work together

    MDB(Main Distribution Board)

    Core functionAs the core node of the low-voltage power distribution system, it is responsible for receiving and distributing power.
    Application scenarioUsually located in the power distribution room or main control room, connected to the sub-distribution cabinet (such as MCC, lighting panel, etc.)

    In summary, MCC is the "execution layer" of motor control, emphasizing flexibility and equipment-level protection. MDB is the "hub" of the power distribution system, focusing on the overall reliability and scalability of power distribution. The application of withdrawable design in both significantly improves maintenance efficiency and system availability, especially suitable for industrial environments with high continuous production requirements.


    Features and Advantages

    • Compact design
      a small space can accommodate more functional units and has high flexibility. Auxiliary circuit scheme number
    • Strong structural versatility and flexible assembly
      C-shaped profiles with a module of 25mm can meet the requirements of various structural forms, protection levels and use environments, and various models and specifications of components can be installed in the cabinet.
    • Adopting standard module design
       It can be composed of standard units such as protection, operation, conversion, control, regulation, testing, indication, etc. Users can assemble them as needed to form fixed partition units or drawer units.
    • Advantages
      According to different electrical equipment, various types of feeder units can be installed in the same cabinet or the same cabinet. For example, the feeder circuit and the motor control circuit can be mixed together.
    • Advantages
      It can provide high standards of reliability and safety. The humanized design strengthens the protection required for personal and equipment safety.
    • Advantages
      MNS is a full range of low-voltage switchgear with high technical performance, suitable for low-voltage systems below 6300A.
    • Compressed site
      The high degree of three-ization can greatly compress the storage and transportation of prefabricated sites.

    Application

    Industrial field
    Used in factories, workshops, petrochemicals and other places, providing flexible power distribution and protection for motors, production lines and other equipment, adapting to frequent start-stop and high load requirements.

    Commercial buildings
    Centralized power distribution in office buildings, shopping malls, hotels and other places, supporting air conditioning, lighting and weak current systems, modular design facilitates expansion and maintenance.

    Infrastructure
    Applied to key facilities such as airports, subways, hospitals, etc., to ensure continuous power supply for primary loads such as fire protection and emergency lighting, with high stability.

    Data Center
    Provide reliable power distribution for precision equipment such as servers and UPS, and the drawer unit can be quickly replaced to reduce the risk of downtime.
