Product model: MZS
Product features: cardiac MNS (MZS) type low voltage switch equipment (hereinafter referred to as low voltage switchgear) is our company according to our country's low village, the development trend of complete switchgear in the appliances in the selection of components and improvements on the structure of cabinet put oneself in another's position, and register the product.The product fully meet the original electrical performance and mechanical properties of MNS product technical requirements.
Derive the low-voltage switchgear is suitable for use in ac 50 ~ 60 hz, rated voltage 660 v and below the power system, as power generation, transmission, distribution, power conversion and power consumption equipment control.
Derive the low-voltage switchgear in addition to the general land use, after special processing can also be used for offshore oil drilling platform, and in nuclear power plant.
Product standards: cardiac GB7251 low-voltage complete switch equipment and control equipment.
Cardiac JB/T9661 low-voltage withdrawable switchgear.
Has it - 1 low-voltage complete switch equipment and control equipment.
Environmental conditions of use: cardiac ambient temperature is not higher than + 40 ℃, and the average temperature is not higher than within 24 h + 35 ℃, the lowest temperature is not lower than 5 ℃.
Is left when the relative humidity at the highest temperature is + 40 ℃ not more than 50%, at lower temperature, allowing a higher relative humidity (example: + 20 ℃ at 90%).
Cardiac altitude does not exceed 2000 m.
Has allowed in 25 ℃ ~ + 50 ℃ temperature under the condition of transportation and storage, and allows the temperature does not exceed + 70 ℃ within 24 h.
Derive seismic intensity less than 9 degrees.
Technical parameters: derive vertical busbar rated current: single-side or double-side operating draw-out MCC is 800 a, portable for 1000 a;Tank depth 1000 mm single operation of MCC is 800 ~ 2000 a. 
Cardiac protection class IP54 due to reduced capacity in severe cases, it is not recommended. 
Product structure: cardiac low-voltage switchgear basic frame for the combination of the fabricated structure, the frame of the whole structure through galvanized processing, 8.8 by tapping screw or hexagonal screw strong connected into the basic frame, then the need to change according to the plan, and combined with the corresponding door, sealing plate, diaphragm, mounting bracket and busbar, functional units and other parts, assembled into a complete low voltage switchgear, switchgear components in size, the size of the compartment for modular (modulus E = 25 mm). 
Cardiac draw-out MCC has five kinds of the size of the drawer, they respectively are 8 e/e / 4, 8, no. 2, 8, 16 and 24 e e e.Eight e/e / 4 and 8, no. 2 two kinds of the structure of the drawer is made of flame retardant plastic and aluminum molding (4 8 e / 4 or 2 8 e / 2 form a e the height of the interval).Functional units compartment of the total height is 72 e.
