GCK Low-Voltage Switch Cabinet: Key Features & Typical Use
The Highest Circuit Density of the Three Series
Eight drawer specifications — 8E/4, 6E/2, 8E/2, 6E, 8E, 12E, 16E and 24E — let one cubicle hold as many as 36 outgoing circuits in 8E/4 drawers. For a plant with a long list of small motor and distribution circuits, that means fewer cubicles, a shorter busbar run and a smaller switchroom footprint for the same number of ways.Interlocked Positions on Every Drawer
All eight drawer sizes provide connected, test and disconnected positions with reliable mechanical interlocking. The result is a repeatable isolation routine: an operator can move a feeder to the test position and verify it without exposing the busbar, regardless of whether the drawer holds a 32 A breaker or a 630 A one.Propulsion Matched to Breaker Size
The smaller 8E/4, 6E/2 and 8E/2 drawers use hand-pull propulsion with FZID metal split adapter units; 6E and 8E drawers also use a pull mechanism, while the larger 12E, 16E and 24E drawers switch to a hand-cranked mechanism. Matching the mechanism to the unit keeps insertion force low and makes accidental partial engagement much less likely.Modular Frame, Repeatable Build
The frame is assembled from 25 mm module C-section steel with an 1800 mm effective height. Because the module grid is carried through the busbar compartment, the cable compartment and the door furniture, a GCK cubicle built for one project can be extended later with a cubicle built for another — the same reason utilities and industrial groups use this platform across several sites.GCK Low-Voltage Switch Cabinet Specifications & Technical Data

GCK — Maximum Outgoing Circuits per Cubicle
Once a switchroom has been designed, the expensive part is the space between the cubicles, not the breakers inside them. The GCK is built to reduce that space: on a 25 mm module frame with an 1800 mm effective height, a single cubicle can carry 36 outgoing circuits in 8E/4 drawers, or a mix of small and large ways without wasted modules.This type is also written as GCK drawer-type low-voltage switchgear or a GCK modular LV switchboard, and it is frequently compared with MNS and GCS boards on the same shortlist. The deciding factor is usually circuit density: where a plant has a long list of small motor and distribution ways, fewer cubicles means a shorter busbar run, a smaller switchroom and less cable — which is worth more than the unit price difference between platforms.Every drawer size offers connected, test and disconnected positions with mechanical interlocking, and the propulsion mechanism changes with the unit: a light pull action for the small drawers with FZID split adapters, a cranked mechanism for the 12E, 16E and 24E units. Service staff get one isolation routine across the whole board.The platform is rated for three-phase 50–60 Hz systems at 400 V (690 V) and below with currents up to 6300 A, and is used for power distribution, centralised motor control and compensation in power plants, chemical and petroleum works, hospitals, railways, airports and mining operations. LYE supplies the GCK factory-direct and builds busbar and compartment layouts around your drawings.Factory-Direct GCK Low-Voltage Switch Cabinet Manufacturer & OEM / ODM
We Manufacture, You Brand
LYE Technology (Zhejiang) Co., Ltd. is a national high-tech enterprise and manufacturer in Wenzhou, China: sheet-metal fabrication, welding, powder coating, busbar machining and final assembly run on our own factory lines, and every unit is function-tested before it leaves the works. A GCK Low-Voltage Switch Cabinet that reaches your site carries the routine test behind it, not just the rating on the nameplate.We are one of the Top 10 Brands of China's small power distribution boxes and a drafter of national standards in this category, and we hold ISO9001, ISO14001, ISO45001, CCC, CE and TUV certification. Because we are the manufacturer rather than a trading company, our sales engineers quote from your drawing in factory-direct terms, and OEM or ODM work is produced on the same lines as our standard products.For the GCK we punch the 25 mm module frame and fit the drawer mechanisms in our own works, so a high-density drawer schedule is a production detail rather than a design change.- OEM branding — custom colours, laser marking and your own project or retail packaging, applied at the factory.
- ODM options — ratings, configurations and internal layouts built around your drawings or single-line diagram.
- Certification — ISO9001, ISO14001, ISO45001, CCC, CE and TUV, with test documents supplied per project.
- MOQ — flexible quantities for a project or a trial order, with mixed types welcome in one shipment.

GCK Low-Voltage Switch Cabinet Buying Guide from the Manufacturer
A GCK board is ordered by drawer schedule rather than by part number, so the checklist below is what we confirm before we release a drawing.
- Confirm the system: three-phase 50–60 Hz, 400 V (690 V) and below, up to 6300 A.
- Count the outgoing circuits and group them by breaker frame to fix the drawer sizes.
- Decide how many cubicles the board needs and allow spare ways for later expansion.
- Confirm the compartment arrangement for incoming, bus-tie, motor control and compensation sections.
- Send the single-line diagram, drawer schedule and site conditions.
- Approve drawings, then assembly, routine testing of every drawer and dispatch with test records.

What is a GCK low-voltage switch cabinet?
It is a low-voltage distribution cabinet assembled on a 25 mm module C-section frame with an 1800 mm effective height, used for power distribution, centralised motor control and capacitor compensation in three-phase 50–60 Hz systems at 400 V (690 V) and below, with rated currents up to 6300 A. It offers eight drawer sizes from 8E/4 to 24E.How many outgoing circuits can a GCK cabinet carry?
Up to 36 circuits in 8E/4 drawers, up to 24 in 6E/2, up to 18 in 8E/2 or up to nine in 8E drawers. Every drawer size provides connected, test and disconnected positions with mechanical interlocking, so the isolation routine is the same whether the drawer holds a small outgoing way or a large feeder, which simplifies operator training and switching procedures.What types of drawer-type switchgear are available?
Modular withdrawable boards are usually grouped by module step and by the drawer sizes offered. A 25 mm step with eight drawer sizes suits a mixed load list and the highest circuit counts, while a 20 mm step with fewer sizes suits medium-sized circuits. Within a board, small drawers use hand-pull propulsion with split adapter units and larger drawers use a hand-cranked mechanism.Who are the main manufacturers of drawer-type switchgear?
The platform names in this category are built by many factories, so the same name can describe quite different equipment. Relevant questions are whether the frame is punched on the supplier's own line, which drawer sizes they actually manufacture rather than buy in, and whether routine test records and type-test documents are issued per project. LYE manufactures the GCK frame, drawers and shell in Wenzhou and holds ISO9001, ISO14001, ISO45001, CCC, CE and TUV certification.How much does a GCK switchboard cost?
Indicative factory-direct pricing is roughly US$1,500 to US$6,000 per cubicle, depending on the drawer schedule, busbar rating, cubicle count and quantity. Because drawer-type boards are configured to the outgoing circuit list, the comparison between suppliers is only meaningful once the drawer sizes, the propulsion mechanisms and the heat load per cubicle have been fixed, so send the schedule for a specific figure.

Use a distribution box for final circuits and compact branch protection; use a cabinet when the project needs larger incoming capacity, more feeder groups, metering, busbars or greater internal separation. The final choice should be checked against the single-line diagram, device list, available installation space and local project rules.
Provide the device schedule, circuit quantity, component dimensions, cable-entry direction, mounting method and required spare capacity. LYE also reviews door clearance, bending radius, heat-producing devices and the usable depth behind the mounting plate before confirming an enclosure size.
Start with the actual exposure to dust, rain, cleaning water and accidental contact rather than choosing the highest number by default. Cable entries, ventilation, door seals and installation workmanship affect the finished assembly, so the target rating and verification basis must be confirmed for the specific product and project.
Coated or galvanized steel is commonly considered for general indoor service, stainless steel for humid or corrosive locations, and engineering plastic for lightweight non-metallic applications. Material grade, thickness, UV exposure, chemical contact and earthing requirements must be confirmed against the installation environment.
Share the component heat load, ambient temperature, solar exposure, duty cycle and allowable internal temperature. LYE can then review enclosure volume, spacing, ventilation or fan provisions, sun shields, heaters or drainage details; the final thermal design remains tied to the installed equipment and site conditions.
Yes. A dimensioned drawing is preferred, but a physical sample and clear reference photographs can also start the review. Material, thickness, openings, hardware, finish, labels, inspection points and packing are recorded before sampling or repeat production.
PDF and common 2D CAD drawings are suitable for most enclosure enquiries, while 3D files can help with complex assemblies. Include a revision number, units, tolerances and component references; file compatibility and any missing production information will be confirmed during review.
A sample or first article can be arranged for a new or customized product. The approval plan should identify dimensions, openings, fit, appearance, hardware, labels and packaging, together with the sample cost and timing agreed for the actual order.
Available documents may include approved drawings, packing lists, dimensional or appearance inspection records, product data and certificates applicable to the confirmed model. Destination-specific declarations or third-party testing must be requested before order placement so availability and scope can be verified.
Lead time is confirmed after the product scope, quantity, sample requirement and finish are known. Packing is reviewed against product weight, surface protection, destination and shipping method; if an issue is found after delivery, send the order reference, label, photographs and quantity affected so it can be traced and reviewed.
