Application and performance

GCK1 series motor control center is mainly combined by some combined motor control units and other functional units. These units are installed in cabinet in the way of upper and lower overlap. While connect each cabinet together by the horizontal bus set on the top of cabinet, the functional units in same cabinet is connected with vertical bus in parallel. The cabinet is divided into four mutual insulated area which are horizontal bus bar room, vertical bus bar room, cable room and installation room. The functional unit is installed in respective room. When anyone is faulty, shall not affect other units to prevent expansion of the accident.

This product is in line with the standards of ZBK36001-89 "Low-voltage drawer-type switchgear" and adopts IP40 protection rating in IEC114. When all the doors and plates are opened or closed, as well as functional units are in out position, it can meet the corresponding protective level. That is to guarantee personal safety. The product is set reliable grounding system and the protective circuit. All functional units are able to break short-circuit current in accordance to regular performance requirements. Input unit has three paragraphs protection characteristics. Therefore, we can guarantee the reliability of electricity supply and security of equipment and system.

All the functional units can be connected with the PC line board (PLC) or computer processors through interface parts. As an executive unit of auto control system, it can provide other functional units and combination on the basis of user's requirements. The product applies to AC circuit of 380V, 50Hz.
