Switch cabinet is through the comprehensive type test, and through the national compulsory product 3C certification. The product conforms to GB7251.1 "low-voltage switchgear and control equipment", EC60439-1 "low-voltage switchgear and control equipment" and other standards. 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. MNS 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 various components can meet the requirements of harsh construction period and power supply continuity. MNS low-voltage pull-out switch cabinet is assembled into modules in factories for ac 50-60Hz, rated working voltage below 660V power supply system MNS switch cabinet is suitable for power supply systems, power plants, substations, industrial and mining enterprises, high-rise buildings, airports, stations, terminals, etc., using 50-60Hz AC, voltage 660V, Power distribution, motor and electrical equipment control, start-up, lighting, power conversion functions, power factor correction.1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h. 2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M. 3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually. 4. Installation gradient not exceed 5. 5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components. 6. Any specific requirement, consult with manufactory.
