The product has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong practicability, novel structure, high protection level, and can be used as the replacement of low-voltage switchgear sets.

In line with national standards: IEC439 "Low-voltage switchgear and control equipment", GB7251-1 "low-voltage switchgear and control equipment" and other standards.

結(jié)構(gòu)特點

柜架用8MF冷彎鋼板局部焊接拼裝而成，其剛性及承載能力均達到電器元件的安裝要求，框架上分別按E=20mm和E=100mm數(shù)排列的安裝孔，以提高產(chǎn)品裝配的通用性。主母線排列在柜體上部，采用ZMJ型母線夾為積木式組合結(jié)構(gòu)，用高阻燃DMC材料熱注成型，機械強度和絕緣度高，能承受有效值50KA，峰值105KA電流，熱穩(wěn)定沖擊力長期允許溫度可達120℃。柜體防護等級IP3X。

Structural characteristics

The cabinet frame is partially welded and assembled with 8MF cold-formed steel plate, and its rigidity and bearing capacity meet the installation requirements of electrical components. The mounting holes on the frame are arranged according to the number of E=20mm and E=100mm to improve the versatility of product assembly. The main busbar is arranged in the upper part of the cabinet, and the ZMJ busbar clamp is a modular combination structure. It is formed by hot injection with high flame retardant DMC material. It has high mechanical strength and insulation degree, and can withstand 50KA effective value, 105KA peak current, and long-term allowable temperature of thermal stable impact force can reach 120℃. Cabinet protection class IP3X.
