UL 508A CERTIFIED Control panels

What is UL 508A certification – and why does it matter?

UL (Underwriters Laboratories) is one of the most trusted safety organizations in the world. A UL 508A certification confirms that an industrial control panel has been designed, built, and tested according to rigorous U.S. safety standards.

This certification ensures that your control panels meet all applicable electrical safety requirements for installation and operation in the United States. It demonstrates your commitment to compliance, reliability, and user protection – all critical factors for operating successfully in North American markets.

WHY UL 508A CERTIFICATION MATTERS FOR YOUR BUSINESS

Accelerate your time for commissioning, reduce project delays, and gain instant credibility.

UL 508A certification confirms that our industrial control panels meet strict U.S. safety standards – ensuring full compliance with the National Electrical Code (NEC) and NFPA regulations.

By meeting these high standards, our panels are approved for use in a wide range of industrial applications across the U.S. This certification minimizes inspection issues, facilitates faster approvals by local authorities (AHJs), and helps avoid costly redesigns or delays.

With these comprehensive tests, you can trust our panels to deliver consistent, dependable operation—no matter how demanding the environment.

Labeling & docomentation: transparency for the market 
 

Every certified control panel is clearly labeled to meet UL 508A requirements and ensure full traceability. We also provide comprehensive documentation of all design and testing processes – delivering the transparency and accountability your business demands.

This clear, standardized approach helps streamline approvals, simplifies inspections, and reinforces trust with your U.S. partners and clients. 

Construction guidelines: Key requirements at a glance
 

UL 508A provides clear instructions for control panel construction – including proper wire routing, component placement and secure connections to ensure full system integrity.

Our panels are meticulously engineered to meet every UL 508A requirement. From material selection and wiring layout to protective measures, each element is carefully planned to minimize risks such as short circuits, overheating, and electric shock. At the same time, we optimize the design for maximum performance, safety and compliance in industrial applications.

Wiring

UL 508A defines strict requirements for internal wiring, covering everything from proper cable type selection to correct routing and fastening. Our wiring is engineered to withstand mechanical stress and thermal loads, ensuring long-term reliability and safety in demanding industrial environments.

Saftey devices

Fuses and circuit breakers are essential for safe operation in case of overloads or short circuits. UL 508A defines minimum standards and recommended protection strategies, ensuring that every panel is equipped to prevent damage, downtime, and safety hazards.

Cooling & ventilation

Control panels naturally generate heat, making effective cooling and ventilation essential to prevent overheating. UL 508A provides clear guidelines for designing ventilation systems and integrating active cooling solutions.

Inspection process in detail

Preparation & planning

A thorough review of all documentation - including schematics, BOMs, and technical specs - is conducted to ensure full compliance with UL 508A standards. Every component must meet strict requirements before approval can proceed.

Material inspection

Inspectors verify that all components  - such as switches, relays, and PCBs - have been tested and certified according to UL standards. Each material must be suitable for its intended purpose and proven to meet the required safety and performance criteria.

Assembly inspection

 All installed components within the control panel are carefully verified for proper installation and wiring, including compliance with overcurrent protection, clearance and spacing requirements, and insulation standards. 

Performance test

The control panel is tested in realistic operating conditions with regard to control response times, protective devices and the simulation of malfunctions.

Documenting the results

Every step of the inspection process is fully documented - not only for quality assurance, but also to support future maintenance and inspections. This clear and traceable documentation serves as proof of standard conformity and demonstrates a strong commitment to product safety.

Where does the certification take place?

There are various ways to obtain an UL certification for a control panel:

 1. On-site certification at the manufacturer’s facility.

The control panel is inspected on-site immediately after completion. UL certification is carried out by inspectors from a “NRTL” (Nationally Recognized Testing Laboratory), i.e. an officially recognized testing institute in the USA such as UL or TÜV Süd. Either an individual approval is possible or the company only builds one certified panel type and obtains the type certification.

2. Certification at the installation site in the U.S.
Alternatively, inspection can take place after installation at the customer’s location in the U.S. However, this method is typically more time-consuming and costly than working with a UL-certified panel builder from the get-go.

Certification process

Final testing & approval

The final stage includes a series of critical safety tests, such as temperature measurements, dielectric (insulation) testing, and mechanical integrity checks. Once the control panel successfully passes all evaluations, it is officially labeled with the UL 508A certification mark, confirming full compliance and readiness for immediate use across North America.
