    Type designation



    Working Conditions
    1.Ambient air temperature: -5℃~+40℃.
    Daily average temperature:≤35℃.
    When the actual temperature exceed the range, it should be used by reducing the
    capacity accordingly.

    Structure feature

    GCK panel is combination structure with bolt. The complete panel is compose of
    door, terminal board , baffle plate ,supporting frame and drawer , busbar , etc.
    Basic frame adopts FA28 type or KB type (C type) to combine with together . T otal
    structural components of frame are connected by self-tapping screw.
    It should add to door, face place, baffle plate, supporting frame and drawer to finish
    completed panel by requirements.
    The installation hole of body and components modules E=25mm change ,flexible
    and convenient to install.
    Drawer unit height divide into ½ unit, 200mm, 300mm, 400mm, 500mm, and
    600mmm series. The loop current decide the drawer height ,virtual installation
    height is 1800mm.
    GCK panel withdrawable function unit adopts special push (pull) mechanism, light
    structure, perfect interchange. It indicate of working position, test position and
    isolating position mechanical locking condition. Install additional pad lock for
    operating handle.
    The frame and inner metal components are galvanized to assure reliable earthing .
    GCK basic frame is combination assembly type structure, adopt standardized module
    design. for combination assembly type structure, the standard module design.
    Compact structure, flexible assembly, can be assembled into a protection,
    measurement and control, indicating etc. standard unit, Can choose assembly
    according to requirement, T o form different frame construction and drawer unit.

    1. The cabinet frame
    1)Parts forming size, hole size ,Equipment interval adopt modularization. (E=25mm)
    2)The internal structure should be galvanized.
    3)The top cover is detachable ,horizontal bus can be installed easily after removing
    the top cover , Hand ring
    4)External phosphating treatment; Then use electrostatic epoxy powder coating.
    5)Cabinet frame is divided into the busbar compartment, functional compartment,
    the cable compartment three separate interval, Can prevent accidents diffusion
    and convenient charged repair .

    2. Functional unit (Withdrawable part)
    1)Functional unit: Feeder unit , Motor unit ,utility power unit.
    2)The high modulus of drawer unit is 200mm, include 1/2unit ,1unit ,2 unit ,3 unit
    four size series.
    Unit loop rated current below 630A.
    3)Each MCC Cabinet can install 9 set drawer with 1 unit , or 18 set drawer with ½
    unit .
    4)The compartment door plate is interlocked between operating mechanism and
    drawer , the door can be open until the main switch is on the close position
    5)The main switch operating mechanism can be locked in close or open position by
    a padlock , the equipment can be maintained safely.
    6)There are main circuit outlet plug ,auxiliar y circuit secondary plug and earthing
    plug at the back of function unit.
    7)The earthing plug make sure the protection circuit continuity when drawer on
    Separation tests connection position.
    8)Functional unit compartment by metal partition board.
    9)Compartment valve, can be open and close automatically, with drawers pushed
    and pulled so that in the compartment without touching the vertical busbar .


    3. Busbar system
    1)Vertical bus uses polycarbonate engineering plastic shell sealed
    GCK, GCL busbar system use 3P4W, 3P5W, Horizontal busbar will be installed at
    2)the top of cabinet, N phase, PE phase.
    and can also be arranged in the cabinet bottom.
    Can be installed on the top of the cabinet,
