Engineered for high-traffic Bulgarian residential and commercial zones
Bulgaria has rapidly transformed into a significant hub for electrical manufacturing and distribution in Southeast Europe. With the expansion of the "Trakia Economic Zone" and various industrial parks in Sofia and Plovdiv, the demand for high-quality Normal GFCI solutions has surged. Local developers are increasingly prioritizing international safety standards, moving beyond basic protections to implement advanced Ground Fault Circuit Interrupters (GFCI) that meet global benchmarks like UL and ETL.
As a leading Normal GFCI Manufacturer serving the Bulgarian market, we understand that the local landscape requires a blend of European aesthetics and robust American-standard performance, especially for international hotel chains on the Black Sea coast and industrial facilities in Ruse and Burgas.
Experience, Expertise, Authoritativeness, and Trustworthiness
Years in Manufacturing
Production Base
Certified Quality
Expert Employees
Founded in 2004, Wenzhou Huaya Electric Co., Ltd. has spent two decades refining the production of American standard electrical appliances. Our modern production base is equipped with automated lines that ensure each Normal GFCI unit leaving our factory meets the most stringent safety criteria. For our Bulgarian clients, this translates to unparalleled reliability in both residential and heavy-duty industrial environments.
The Bulgarian construction sector is witnessing a shift towards "Smart Building" technologies. GFCI outlets are no longer just safety components; they are now integrated parts of a building's intelligent energy management system.
In the industrial zones of Sofia-Bozhurishte, our GFCI products are utilized in manufacturing plant breakrooms and laboratory environments where precision and safety are non-negotiable. Our 20 Amp models are particularly favored for their ability to handle heavy equipment loads while providing sensitive ground-fault protection.
We have a team of over 200 employees including skilled workers, electrical engineers, production specialists, and quality control experts who collectively maintain our manufacturing excellence. We always adhere to the best practices in product development and manufacturing technology. The research and development department plays a particularly vital role, having secured multiple utility patents in both China and the United States for innovative product designs and manufacturing processes.
Quality assurance forms the foundation of our operations, with certifications including ISO9001 for our quality management system and product approvals from UL and ETL - the most recognized certifications for the international market.
High-quality materials and precision craftsmanship for European developers

High-quality materials and precision craftsmanship, undergoing strict safety inspections, offer reliable ground fault protection—tripping within 0.025 seconds to quickly block hazards. Designed for damp environments like the Bulgarian coastline, it safeguards electrical safety in bathrooms and kitchens effectively.
Integrated USB ports cut clutter by ditching extra adapters. Multi-port design lets multiple devices charge at once, fitting the modern tech-focused apartments in Sofia's Studentski Grad or office spaces in Business Park Sofia.


Crafted with over 30,000 press life tests, our switches guarantee reliable quality for large-scale Bulgarian housing projects. Suitable for living rooms, bedrooms, and studies where durability is paramount.
Ensuring compliance with API 6D, API 607, CE, ISO9001, and more.
Wholesale opportunities for Bulgarian distributors and contractors
As a gateway between Europe and Asia, Bulgaria offers a unique strategic advantage for the distribution of Normal GFCI technology. Manufacturers in this region are not just suppliers but partners in ensuring the structural integrity of European electrical grids. With the rise of Electric Vehicle (EV) charging stations across the A1 and Struma motorways, the need for integrated GFCI protection at the point of use has become a critical topic in Bulgarian engineering forums.
Our commitment to the Bulgarian market is backed by deep expertise in North American standards, which are often adopted by Bulgarian firms working on overseas construction projects. By choosing a manufacturer with over 20 years of experience, Bulgarian distributors gain access to products that have been tested in the world's most demanding markets.
