GCS型低壓開關柜一般都設有清晰的3段位置，GCS型抽屜式開關柜有個較大的缺點，其結構制作，尤其是裝配比較麻煩，大多采用螺栓連接，抽屜分為1/2單元、1單元、1.5單元、2單元、3單元五個系列，PC柜多可做3個，MCC柜多可裝22個抽屜回路，主柜安裝模數孔E=20mm和100mm，抽屜層高160mm，母線采用背后平置式，電纜室上下均有出線通道，面板具有分、合、試驗、抽出位置的明顯標志。

GCS type low-voltage switchgear is generally equipped with clear 3-section positions. GCS type drawer type switchgear has a major disadvantage. Its structure fabrication, especially assembly, is troublesome, and most of them are connected by bolts. The drawers are divided into five series: 1 / 2 unit, 1 unit, 1.5 unit, 2 unit and 3 unit. There can be at most 3 PC cabinets and 22 drawer circuits in MCC cabinet, The installation module hole of the main cabinet is e = 20mm and 100mm, the drawer layer height is 160mm, the bus is flat at the back, there are outlet channels at the top and bottom of the cable room, and the panel has obvious signs of opening, closing, test and extraction positions.

GCK型低壓開關柜具有分斷能力高、動熱穩定性好、結構先進合理，GCK型抽屜式開關柜電氣方案靈活、系列性、通用性強、各種方案單元任意組合、一臺柜體。

GCK type low-voltage switchgear has high breaking capacity, good dynamic and thermal stability, advanced and reasonable structure. GCK type drawer type switchgear has flexible electrical scheme, strong seriality and universality, arbitrary combination of various scheme units and one cabinet.

所容納的回路數較多、節省占地面積、防護等級高、安全可靠、維修方便等優點，抽屜分為1/2單元、1單元、2單元、3單元，多可裝9個單元，柜體可裝18個單元。抽屜具有合、分、試驗、抽出位置，即能保證正常的工作，又可安全檢修抽屜內的元件，從抽屜的推進方式上又基本上分單撥插式，雙撥插式，搖進式。

The drawer has the advantages of large number of circuits, saving floor area, high protection level, safety and reliability, convenient maintenance, etc. the drawer is divided into 1 / 2 unit, 1 unit, 2 unit and 3 unit, up to 9 units can be installed, and the cabinet can be installed with 18 units. The drawer has closing, opening, testing and extraction positions, which can not only ensure normal operation, but also safely overhaul the components in the drawer. From the propulsion mode of the drawer, it is basically divided into single pull-in type, double pull-in type and swing in type.

有的抽屜單元大多數沒有清晰的3斷位置，只能實現基本的連鎖，大多數沒有實驗位置，主架安裝模數孔E=25mm，GCK型抽屜式開關柜抽屜柜高度為1800mm，每一功能單元均占一獨立隔室，抽屜層高200mm，但隨著電氣工業的發展，斷路器體積越來越小，亦可水平安裝。

Most of some drawer units have no clear 3-off position and can only realize basic interlocking. Most of them have no experimental position. The installation module hole of the main frame is e = 25mm. The height of the drawer cabinet of GCK drawer switch cabinet is 1800mm. Each functional unit occupies an independent compartment and the drawer floor height is 200mm. However, with the development of the electrical industry, the volume of the circuit breaker is getting smaller and smaller and can also be installed horizontally.

MNS型低壓開關柜結構為組合式，MNS型抽屜式開關柜它分為標準型和非標型，框架的全部結構件經過鍍鋅或采用鍍鋅板、進口敷鋁鋅板折成型材。

The structure of MNS low-voltage switchgear is combined, and MNS drawer switchgear is divided into standard type and non-standard type. All structural parts of the frame are galvanized or folded into profiles by galvanized plate and imported aluminum zinc coated plate.

模數孔E=25mm，通過各種聯結件、自攻鎖緊螺釘和8.8級六角螺栓聯結，框架結構無需專用工具即能組裝，柜內隔板采用分段式多功能隔離板，可使PC柜和MCC柜實現混裝，抽屜層高200mm，可分為8E/4、8E/2、8E、16E、24E，MCC柜的有效高度為72E，多可裝36個出線回路。

Modular hole e = 25mm, which is connected through various connectors, self tapping locking screws and grade 8.8 hexagon bolts. The frame structure can be assembled without special tools. The partition plate in the cabinet adopts segmented multi-functional isolation plate, which can realize mixed loading of PC cabinet and MCC cabinet. The drawer layer height is 200mm, which can be divided into 8e / 4, 8e / 2, 8e, 16e and 24E. The effective height of MCC cabinet is 72e, and 36 outgoing circuits can be installed at most.
