MNS Type Low Voltage Draw-out Switch Cabinet

MNS Type Low Voltage Draw-out Switch Cabinet

Product Introduction

MNS type low voltage draw-out switch cabinet ( hereinafter called switch cabinet) is designed and developed by ourselves, combining with the status of domestic low voltage switchgear. It belongs to new generation of drawer type switch cabinet. Novel structure, compact and reasonable layout, advanced and reasonable component modeling, meet the needs of electric system with AC50-60HZ, 4000A rated current and 660V rated voltage or less, as a controlling equipment of power generation, transport, distribution and change. Thus, switch cabinet is widely used in power plants, substations , factories, mines, petroleum, chemical, high-rise buildings and other power distribution sites.

 

Product features

The main frame is molded by pressing C-type aluminum-zinc sheet metal forming, is whole assembly structure. Structure is compact, can operate on the positive side, also can be on the opposite side, protective level of casing is IP3X.

Each function chamber is isolated from each other, divided into function unit chamber, bus-bar chamber and cable chamber. The role of each chamber is relatively independent.

Horizontal main bus-bar adopts “laid flat after cabinet ”arrangement method, to enhance the ability of bus-bar’s anti-electric, then aid the main power lines gain the capability of bearing high short-circuit strength. 

Drawers can be designed to 1/4 、1/2、1、2、3, these five standard drawer unit, drawer unit is equipped with mechanical interlock devices. Use high-strength flame- retardant engineering plastics to form, with high security.

Switch cabinet has two outlet types: right outlet and rear outlet

Don’t need special、complicated tools, easy to install
