From international certifications to military-grade approvals, here’s why the CMCE stands superior in the lightning protection industry:
UL Certificate of Compliance No. 20191118-E505360
This certification from Underwriters Laboratories (Now “UL Solutions”)
confirms the CMCE-120-UL Lightning Suppressor
meets essential U.S. safety standards. UL is one of the most recognized independent safety science companies in the world, making this an important marker of reliability and performance.
ISO 9001:2015 & ISO 14001:2015 Certifications
Quality and environmental stewardship are at the core of the CMCE.
- ISO 9001:2015 certifies that the CMCE manufacturing process follows internationally recognized standards for quality management.
- ISO 14001:2015 ensures the manufacturer’s commitment to environmentally responsible production practices.
Together, these certifications represent a system built with care — both for performance and the planet.
Tested by the High Voltage Laboratory – Tesla Institute
The CMCE Lightning Suppressor
has been tested and approved by the Tesla Institute
in Belgrade, Serbia. As an evolution of Nikola Tesla’s original patent, the CMCE operates on principles of pure capacitance, capable of functioning at various frequencies to prevent lightning formation altogether. This scientific validation connects historic innovation with modern technology.
Compliance with IEC, UNE-EN, and BS-EN 62305 (Parts 1-4)
These international standards set the benchmark for lightning protection systems across Europe and beyond. CMCE’s compliance with all four parts of the IEC 62305
standard means our suppressors address:
- General principles
- Risk management
- Physical damage to structures
- Electrical and electronic systems
This comprehensive coverage ensures that CMCE is engineered to protect all aspects of a structure or area.
NATO Codification (NCAGE Code: SFKU3)
Our system is recognized under the NATO Codification System, which speaks volumes about the reliability and security of the CMCE device for use in military and governmental applications. Few systems meet this level of approval, making it a standout in global defense and critical infrastructure protection.
CE & UKCA Marking
All CMCE models carry both the CE (European Union) and UKCA (United Kingdom) markings. These demonstrate full compliance with each region’s product safety and quality regulations, ensuring legal placement in those markets and reinforcing product credibility.
Lloyd’s Register & RINA Type Approvals
- Lloyd’s Register Certificate No. LR2514641TA
- RINA Certificate No. ELE281223XG
These internationally respected marine and industrial certifications confirm the CMCE's fitness for use in offshore platforms, ships, and high-risk industrial environments. When it comes to protecting critical operations, these approvals speak volumes.
Green Recycling Seal
In addition to being technologically advanced, the CMCE is environmentally conscious. All models are manufactured using 100% recycled materials, reflecting our commitment to protecting not only people and property — but also the planet.
Each of these certifications, approvals, and standards proves one thing: The CMCE Lightning Suppressor
is built to perform, built to last, and built to protect. Whether you’re a homeowner, a commercial developer, or a boat captain, you can trust that your investment in CMCE is backed by rigorous global testing and compliance.
