Overview
This AC low-voltage fixed switchgear cabinet is built on an 8MF cold-bent steel frame. The components are modular and the frame provides 20 mounting holes, which supports pre-production of standard assemblies and shortens the manufacturing cycle.
Heat dissipation slots are provided at the top and bottom of the cabinet. Together they form a natural ventilation duct, so heat generated by the installed equipment can escape without forced cooling.
The cabinet shape follows the golden ratio. The door is fitted with rubber strips, the instrument door is bonded to the frame with soft copper wire, and the grounding arrangement is complete. The finish is polyester orange-shaped baking paint, the top cover is detachable, and lifting rings are provided for handling. The standard protection level is IP30, with IP20 to IP40 available.
Key Features
- 8MF cold-bent steel frame — the frame is formed from 8MF cold-bent steel, which gives a rigid structure for a fixed switchgear cabinet.
- Modular components and 20 mounting holes — the modular arrangement and the pre-formed mounting holes allow pre-production of standard assemblies for a short cycle and high efficiency.
- Natural ventilation duct — heat dissipation slots at the top and bottom of the cabinet form a natural ventilation duct, removing heat without forced cooling.
- Complete grounding arrangement — the instrument door is connected to the frame with soft copper wire, and the grounding is complete throughout the cabinet.
- Sealed door design — the cabinet door is fitted with rubber strips to limit the ingress of dust.
- Selectable protection level — the standard rating is IP30, and IP20 to IP40 can be selected according to the installation environment.
- Practical mechanical details — the top cover is detachable and lifting rings are provided to simplify handling and on-site installation.

Applications
- Industrial facilities — low-voltage power distribution inside factories and processing plants.
- Commercial and public buildings — distribution boards for lighting, power and auxiliary circuits.
- Substations and distribution rooms — low-voltage side distribution in substations and switchrooms.
- Infrastructure projects — low-voltage distribution for utility and public infrastructure installations.
Installation Conditions
- The cabinet is a fixed installation type, so the equipment position is set at the outset rather than being withdrawable.
- Maintain clearance above and below the cabinet so the natural ventilation duct is not obstructed.
- Verify that the protection level matches the environment — IP30 as standard, with IP20 to IP40 available.
- Use the lifting rings during handling to avoid distorting the frame.
How to Select
- Rated voltage, rated current and short-circuit withstand level of the system.
- Number of incoming and outgoing circuits required.
- Metering and protection functions required for each circuit.
- Cable entry arrangement and the installation environment.
- Required protection level — IP20 to IP40, with IP30 as the standard rating.
FAQ
What does fixed switchgear mean?
A fixed switchgear cabinet has the switching and protective devices bolted into position rather than mounted on withdrawable trucks. This makes the cabinet simpler and more compact than a drawout design, with the equipment position set at the outset.
What is the 8MF cold-bent steel frame?
The frame is formed from 8MF cold-bent steel profiles. The profiles form a rigid structure and are pre-formed with 20 mounting holes, which allows modular components to be positioned during pre-production.
How is the cabinet ventilated?
Heat dissipation slots are provided at both the top and the bottom of the cabinet. Together they form a natural ventilation duct, so heat generated by the installed equipment rises and escapes without requiring forced cooling.
What protection level does the cabinet provide?
The standard protection level is IP30, and IP20 to IP40 can be selected according to the conditions at the installation site.
How is the grounding arranged?
The grounding arrangement is complete throughout the cabinet, and the instrument door is bonded to the frame with a soft copper wire so the door stays electrically continuous with the cabinet body.
Can the cabinet be handled and installed on site easily?
Yes. Lifting rings are provided for handling, and the top cover is detachable, which simplifies both transport and installation work on site.
