MNS Low-voltage switchgear

MNS low-voltage suction switchgear is a combined low-voltage switchgear (hereinafter referred to as device) assembled with standard modulus. This device is suitable for the power supply and distribution system with a rated working voltage of 50 (60) Hz of 690V and below, and is used for the control of power generation, transmission, power conversion and power consumption equipment.

The device conforms to the national standard of IEC439.VDE.660 and GB7251.1 "Low-voltage Complete Switchgear and Control Equipment", and has passed the "3C" mandatory product certification.

◎ low voltage switchgear features

■ Compact design: in a smaller space that can accommodate more functional units. Up to 368E / 4 drawer units are available.

■ Strong structural versatility, flexible assembly: 25mm modular C profile can meet the requirements of various structural forms, protection grade and use environment.

■ Adopt standard module design: respectively can form different protection, operation, conversion and other standard units, users can choose any assembly according to the needs. More than 200 kinds of assembly parts can form the frame structure and drawer unit of different schemes.

■ High safety: a large number of high-strength flame retardant engineering plastic components, effectively strengthen the protection and safety performance, with arc protection design, personal safety protection of operators.

■ High technical performance: the main parameters reach the contemporary international technical level.

■ Convenient assembly: no need for special complex tools, the full range of standardization.

■ The plate uses cold plate or aluminum-coated zinc plate, and the cabinet body is free of maintenance.

■ Equipment update and improvement are convenient.

◎ Normal use of environmental conditions

■ The surrounding air temperature shall not be higher than + 40°C, not lower than-10°C, and the average temperature within 24 hours shall not be higher than + 35°C.

■ Atmospheric conditions: air is clean, relative humidity does not exceed 50% when the highest temperature is + 40°C, and large relative humidity is allowed at lower temperatures, such as 90% at + 20°C, but it should be considered that moderate condensation may be generated occasionally due to temperature changes.

■ For indoor use, the altitude of the use site shall not exceed 2,000 m.

■ The device is adapted to the transport and storage process at the following temperatures: -25°C from + 55°C to + 70° C for a short time (not exceeding 24h) and shall not suffer any unrecoverable damage at these limit temperatures.

■ If the above use conditions cannot be met, they shall be negotiated by the user and the manufacturer.

■ When the device is used in the offshore drilling and production platform and nuclear power plant, a separate technical agreement shall be signed.
