符合国家标准：IEC439-1、GB7251、ZBK36001以及BS5486等标准。

Application and performance

MNS combined low-voltage switchgear is widely used in industrial and mining enterprises, power plants, petrochemical, commercial and residential buildings central air conditioning system. As AC 50-60HZ, rated voltage AC 660V and below power system distribution and motor centralized control.

In line with national standards: IEC439-1, GB7251, ZBK36001 and BS5486 standards.

结构特点

1、框架为组合式结构，基本骨架由C型钢材组装而成。

2、每一个柜体分隔为三个室，即水平母线室、抽屉小室、电缆室。各隔室之间用钢板或高强度阻燃塑料功能板相互隔开，上下层抽屉之间有带通风孔的金属板隔离，用以有效防止开关元件因故障引起的飞弧或母线与其它线路短路造成的事故。

3、设计紧凑：以较小的空间容纳较多的功能单元。

4、各种大小抽屉的机械联锁机构符合标准规定，有连接、试验、分离三个明显位置，安全可靠。

Structural characteristics

1,The frame is a combined structure, and the basic skeleton is assembled by C-type steel.

2, each cabinet is divided into three rooms, namely horizontal bus room, drawer room, cable room. The compartments are separated from each other by steel plates or high-strength flame-retardant plastic functional boards, and metal plates with ventilation holes are isolated between the upper and lower drawers to effectively prevent the flying arc caused by the failure of the switching element or the accident caused by the short circuit between the bus and other lines.

3, compact design: to accommodate more functional units in a smaller space.

4, the mechanical interlocking mechanism of various sizes of drawers meets the standard provisions, and there are three obvious positions of connection, test and separation, which are safe and reliable.
