The drawer-type switch cabinet is made of a steel plate with a closed enclosure. The electrical components of the incoming and outgoing line circuits are installed in a drawer that can be drawn out to form a functional unit that can complete certain types of power supply tasks. The functional unit and the bus or cable are separated by a grounded metal plate or a functional board made of plastic to form three areas of the bus, functional unit and cable. There are also isolation measures between each functional unit. Drawer switchgear has higher reliability, safety and interchangeability. It is a relatively advanced switchgear. Most of the currently produced switchgear are drawer-type switchgear. They are suitable for industrial and mining enterprises and high-rise buildings that require high reliability of power supply, as a centralized control power distribution center.

Select the height of the switch cabinet drawer:

  It is to find out the maximum capacity of various drawer specifications according to the specific model of the switch cabinet. First, the drawer capacity must be greater than or equal to the circuit capacity.

  According to the external dimensions of the circuit breaker and other components in the circuit, refer to whether the drawer's limited installation space can be arranged in the drawer.

The wiring method is generally divided into front panel, back panel, plug-in type, and withdrawable type. The front or back panel of the drawer is selected based on the current and the installation position of the circuit breaker in the drawer. If the space in the drawer is sufficient, it can meet the cable routing. Then select the wiring before the board. If the circuit breaker occupies a large amount in the drawer, the wiring after the board can only be used if the wiring cannot be done before the cable board. The plug-in type and the withdrawable type are generally used for fixed installation of circuit breakers (fixed directly in the cabinet, no drawers). I personally understand that it is also equivalent to a drawer. When the circuit breaker is damaged and repaired, it can extract the circuit breaker body from the live conductor Convenient maintenance, mostly used for fixed partition cabinet. MNS, 200MM: 1/4 unit below 63A, I only know S1-80 from ABB, CM1-63 from Changshu, NS-80 ~ 100 from Schneider, etc .; 1/2 unit below 100A 1 unit below 250A,

2 units greater than 250A, 3 units of 630A plastic case or fixed installation with frame circuit breaker.

  GCK, 200MM: 1/2 unit below 100A, 1 unit below 250A, 2 units above 250A, 3 units for 630A plastic case

Or use a frame breaker for fixed installation.

GCS, 160 mode: 1/2 unit below 63A, 1 unit below 160A, 1.5 unit at 250A, 2 units at 400A. The 630A plastic case is fixedly installed with 3 units or a frame circuit breaker.
