Overview

     MNS is a modular, multifunctional low-voltage distribution cabinet.It is applied to all low-voltage systems requiring high reliability field connection in the fields of metallurgy, petroleum,chemical, industrial and mining enterprises and infrastructure, etc. : distribution and motor control systems.MNS adopts a cabinet structure with a high degree of flexibility.

    According to your needs or different occasions of use, the cabinet can be installed in a variety of models and specifications of components;According to different electrical equipment, multiple types of feeding units can be installed in the same column cabinet or the same cabinet.For example: feed circuit and motor control circuit can be mixed together.

    MMNS is a full range of low voltage switchgear to meet your full range of requirements.

    Suitable for all low pressure systems up to 4000A.MNS can provide a high level of reliability and security.

    The humanized design strengthens the necessary protection for personal and equipment safety.

    MNS is a fully assembled structure, and its unique profile structure and connection mode as well as the compatibility of variouscomponents can meet the requirements of harsh construction period and power supply continuity.
