Control Panel Standards
Building Control Panels That Meet Industry Standards
Industrial control panels are expected to do more than simply operate machinery. They must be designed, manufactured and tested to recognised standards that promote safety, reliability and long-term performance.
Whether you are installing a new production line, upgrading existing equipment or replacing ageing control systems, understanding the standards that apply to your control panel helps reduce project risk and supports ongoing compliance.
At Stratos, every control panel is designed with applicable British and international standards in mind, ensuring systems are built to support safe operation throughout their lifecycle.
Why Control Panel Standards Matter
Following recognised standards helps organisations:
• Improve operator safety
• Reduce electrical hazards
• Improve reliability and maintainability
• Simplify inspections and commissioning
• Support future modifications and upgrades
• Reduce the likelihood of costly downtime
• Demonstrate good engineering practice
Standards also provide consistency throughout the design, manufacture, testing and documentation process, helping projects progress more smoothly from design through commissioning.
BS EN 61439
BS EN 61439 is the principal British and European standard governing low-voltage switchgear and controlgear assemblies.
It specifies requirements for:
• Electrical performance
• Mechanical strength
• Temperature rise
• Short circuit withstand capability
• Internal construction
• Component compatibility
• Protection against electric shock
• Environmental performance
For industrial control panel manufacturers, BS EN 61439 provides the framework for designing assemblies that perform safely under their intended operating conditions.
IEC 60204-1
IEC 60204-1
IEC 60204-1 focuses specifically on the electrical equipment of machinery.
It provides guidance on designing electrical systems that minimise hazards while ensuring equipment remains safe to install, operate and maintain.
The standard covers areas including:
• Emergency stop circuits
• Isolation and disconnecting devices
• Protective bonding
• Electrical protection
• Control circuit design
• Wiring methods
• Cable identification
• Documentation requirements
Following IEC 60204-1 helps ensure machinery electrical systems are designed with operator safety and maintainability in mind.
Machine Safety
Control panels form part of the overall machine safety strategy.
Good control panel design considers:
• Safe isolation
• Emergency stop functionality
• Functional safety requirements
• Appropriate enclosure selection
• Environmental protection
• Safe component layout
• Clear identification and labelling
• Maintenance accessibility
By considering machine safety from the beginning of a project, organisations reduce operational risks while supporting safer maintenance and future expansion.
Electrical Safety
Electrical safety extends beyond selecting quality components.
A well-designed industrial control panel considers:
• Appropriate protective devices
• Correct cable sizing
• Earthing and bonding
• Fault protection
• Short circuit protection
• Separation of power and control wiring
• Suitable ingress protection (IP) ratings
• Safe working clearances
These design principles help protect personnel while improving system reliability.
Design Verification
Before a control panel enters production, the design should be verified to confirm it meets the intended performance requirements.
Design verification may include assessment of:
• Temperature rise
• Dielectric properties
• Protective circuit effectiveness
• Short circuit withstand capability
• Mechanical operation
• Degree of protection (IP rating)
• Component suitability
• Assembly construction
Design verification provides confidence that the control panel has been engineered appropriately for its intended application.
Standards Are Only Part of Good Engineering
Meeting recognised standards is an important part of building reliable industrial control panels, but successful projects also depend on practical engineering experience, quality manufacturing processes and comprehensive documentation.
At Stratos, we combine industry best practice with robust design, careful manufacturing and thorough testing to deliver control panels that support safe, reliable operation across a wide range of industrial applications.

Frequently Asked Questions
What is BS EN 61439?
BS EN 61439 is the primary standard covering low-voltage switchgear and controlgear assemblies, including many industrial control panels. It defines performance and safety requirements for panel design and construction.
What is IEC 60204-1?
IEC 60204-1 is an international standard covering the electrical equipment of machinery. It provides guidance on designing electrical systems that improve operator safety and equipment reliability.
Is every industrial control panel required to comply with these standards?
The standards that apply depend on the application, equipment and intended use. A qualified control panel manufacturer will determine which standards are appropriate for each project.
What is the difference between design verification and routine verification?
Design verification confirms the panel design meets required performance criteria, while routine verification checks that each completed panel has been manufactured correctly before delivery.
Why are control panel standards important?
Recognised standards improve safety, reliability, consistency and maintainability while helping reduce project risk and supporting successful commissioning.
