符合國家標準：IEC439-1、GB7251、ZBK36001以及BS5486等標準。

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.

結構特點

1、框架為組合式結構，基本骨架由C型鋼材組裝而成。

2、每一個柜體分隔為三個室，即水平母線室、抽屜小室、電纜室。各隔室之間用鋼板或高強度阻燃塑料功能板相互隔開，上下層抽屜之間有帶通風孔的金屬板隔離，用以有效防止開關元件因故障引起的飛弧或母線與其它線路短路造成的事故。

3、設計緊湊：以較小的空間容納較多的功能單元。

4、各種大小抽屜的機械聯鎖機構符合標準規定，有連接、試驗、分離三個明顯位置，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.
