Turnkey switchgear assemblies including enclosure, wiring and automation. You provide your circuit diagram – we deliver the fully wired, tested system. Enclosure selection or manufacture To project requirements. Complete assembly with all electrical components. Wiring and tubing in accordance with standards. Functional testing and logging. Assembly preparation and on-site commissioning support available. From single cabinets to complex multi-panel switchgear. Everything from a single source – one point of contact for your project.
Bespoke solutions in control cabinet construction – WCU & custom manufacturing
We develop bespoke solutions for mechanical and structural challenges concerning housings, fastening techniques or the joining of different materials. In close collaboration with our customers, we create individual adaptations that optimally combine functionality, design and practical suitability. One example is the WCU – WITTWER Control Unit, which was specially developed for the expansion of Siemens Pro Panel applications. It impresses with its high adaptability, user-optimised design and well-conceived enclosure engineering by our specialists.
Commissioning electrical cabinet construction – it’s that simple
In five steps from the initial enquiry to the fully wired switchgear assembly:
1. Enquiry: You tell us about your project – via a project description or in a personal conversation.
2. Circuit diagram & parts list: You supply us with your circuit diagram (e.g. as a PDF) as well as the parts list of the components; if required, we will support you with the planning.
3. Quotation: Based on your documents, you will receive a bespoke quotation for your project.
4. Manufacturing & wiring: We assemble and wire your switchgear according to the circuit diagram – including labelling, identification and documentation.
5. Functional testing & delivery: Before delivery, we test the system's operation and supply you with the fully wired, ready-to-ship switchgear.
Frequently asked questions about control cabinet construction
What exactly does control cabinet construction at Wittwer GmbH encompass?
Our control cabinet construction encompasses the complete assembly and wiring of your control system according to your wiring diagram – from equipping it with contactors, frequency converters, PLC controllers, and terminal blocks to compliant wiring, labelling, and final functional testing. If desired, we can also take care of housing selection or manufacturing, as well as technical documentation according to the Machinery Directive. You will receive a fully wired, tested, and ready-to-ship system – all from a single source.
From what order quantity do you accept control cabinet construction orders?
We manufacture from a single unit. Whether you need a single housing for a prototype, a small series or recurring series production – we calculate for every batch size. There is no minimum order quantity. This model is particularly in demand for individual and special projects in mechanical and plant engineering.
What is needed for a control cabinet construction order?
Ideally, you would provide us with your circuit diagram (e.g. as a PDF), a bill of materials for the components used, as well as details about the housing and installation conditions. If you do not yet have a finished circuit diagram, we would be happy to help you with the planning. Simply send us a project description – we will get in touch for an initial consultation.
What standards do you wire to?
We wire in accordance with the applicable IEC/DIN EN standards for switchgear assemblies. All qualified electricians employed work according to recognised engineering standards – quality and standard compliance are a matter of course for us, not optional.
How long does it take to manufacture an electrical cabinet?
The lead time depends on complexity, component availability, and order volume. We typically realise simple control cabinets within 2-4 weeks after the electrical schematic has been approved. For complex systems with multiple bays or long delivery times for special components, we will agree on a realistic schedule with you in advance. For time-critical projects, please contact us directly.
Do you also offer complete solutions including housing?
Yes. As a manufacturer of industrial enclosures, we can supply you with switch cabinets and enclosures from a single source. We select the appropriate standard enclosure or manufacture a custom enclosure to your dimensions and requirements. This saves coordination effort and interfaces – one point of contact for the entire project.
What is the difference between control cabinet manufacturing and switchgear manufacturing?
Control cabinet manufacturing refers to the production and wiring of individual control cabinets – from component assembly to the operational system. Switchgear manufacturing encompasses larger systems, often composed of multiple panels. At Wittwer GmbH, you get both from a single source: from the compact control unit to the complex multi-panel switchgear.
Do you also undertake the retrofit of existing control cabinets?
Yes. Alongside new builds, we also undertake retrofitting and modernisation of existing control cabinets – from updating individual components to complete rewiring in accordance with current circuit diagrams.
Which components do you install in your control cabinets?
Depending on your requirements, we integrate contactors, frequency converters, PLC controllers, terminal blocks and safety technology, among other things – tailored to your circuit diagram and intended application.
