Control cabinet manufacturing for industrial companies

Control cabinet services: engineering, manufacturing and testing

You can engage Gross Schaltschrankbau for individual work packages or for a coordinated overall process. The specific scope is defined on the basis of your documents, quantities, target markets and test requirements.

Which services does control cabinet manufacturing at Gross Schaltschrankbau include?

Gross Schaltschrankbau covers three areas: engineering translates your requirements into schematics, bills of materials and manufacturing documents. Manufacturing turns these approved documents into control cabinets and switchgear assemblies – mechanical machining, assembly, component mounting, wiring and cable assembly. Testing checks the result against the agreed requirements and documents it for handover. Each area can be commissioned individually; together they form a continuous process chain from specification to tested system.

Project workflow

From requirements to documented handover

Every project follows the same sequence: clarify, define, approve, manufacture, test. The difference lies in the entry point – some projects start with an idea and a specification, others with fully approved schematics from your own design department.

The first two steps determine the cost of the last ones. Defining interfaces, target market and test requirements early avoids changes to systems that have already been built. A correction in the schematic takes minutes – the same correction on the wired system takes hours and creates additional testing effort.

Approval is the handover point between planning and manufacturing. From here on, the documented status is binding; later changes are handled as a traceable change process with their own approval. This protects both sides: you know what is being built, and we know what will be tested against at the end.

Not every project needs all five steps from us. If you bring approved documents, our cooperation starts with manufacturing. If the system has not yet been fully designed, we take over from requirements gathering. What matters is that the handover points are clearly defined.

01

Review request

Review documents, quantities, schedules and operating conditions.

02

Clarify technical details

Agree interfaces, target markets, components and verifications.

03

Secure approval

Approve schematics, bills of materials and changes in a traceable manner.

04

Manufacture

Machine, assemble, mount components and wire.

05

Test & hand over

Document the agreed scope of testing and prepare delivery.

Standards & verifications

What we manufacture and test against

Which regulations apply in a specific project depends on the application, target market and the customer's plant standard. We clarify these points before production starts.

Regulations

Basis for the design and construction of the switchgear assembly.

Testing & documentation

Verifications handed over with the system.

Organisation

How traceability is ensured throughout the project.

Frequently asked questions

Questions about ordering and the process

Can I commission individual services or only the complete package?

Individually. Engineering, manufacturing and testing can each be ordered separately. Many customers bring their own schematics and only have us manufacture; others hand over the complete process chain from the specification onwards. What matters is that interfaces and responsibilities are defined in advance.
Ideally a schematic or specification, a bill of materials, details of quantities and timeframe, as well as operating conditions and target market. If not everything is available yet, a description of the application is enough for an initial assessment – we will clarify the missing points with you.
Yes. We check the documents for manufacturability and completeness and report any questions before production starts. The approved revision is the basis; deviations are handled as a documented change process.
Which regulations apply depends on the application, target market and plant standard. As a rule, these are DIN EN 61439 for the switchgear assembly and DIN EN 60204-1 for the electrical equipment of machines.
That depends on scope, quantity, material availability and how quickly approvals are given. In our experience, the approval loop has the greatest impact: the sooner the final manufacturing documents are approved, the sooner procurement and production can begin.
Yes, through retrofit and modernisation. Existing switchgear assemblies are surveyed, assessed and brought to a defined target state. The scope ranges from replacing individual components to rebuilding the entire system.
