Bulgaria is currently undergoing a significant energy transformation. Under the National Recovery and Resilience Plan (NRRP), the country is prioritizing the integration of renewable energy sources, particularly utility-scale solar and distributed residential PV systems. This shift creates an urgent demand for high-reliability Miniature Circuit Breakers (MCB) and DC Surge Protective Devices (SPD) that comply with stringent EU safety standards (EN 60947-2, EN 60898-1).
The future of Bulgarian power distribution is "Smart" and "Resilient." As a leading MCB manufacturer, Shuorui Electric is moving beyond traditional thermal-magnetic tripping mechanisms. Our technical roadmap for the Balkan region focuses on:
Located in Liushi, the "Electrical Capital of China," Zhejiang Shuorui Electric Co., Ltd. leverages a smart manufacturing ecosystem to serve the Bulgarian market. Our Factory 4.0 initiatives include:
Precision Automation: 95% of our MCB assembly is automated, ensuring that every unit destined for Bulgarian distributors has identical tripping characteristics and contact resistance.
Supply Chain Integrity: We source silver contacts and flame-retardant plastics from top-tier global suppliers, ensuring that our products withstand the fluctuating temperatures of the Bulgarian continental climate (from -40°C to +70°C).

Each MCB undergoes 13 rigorous tests, including short-circuit breaking capacity and mechanical endurance, exceeding IEC 60898 standards.
From 1A to 125A, AC to DC, and SPD to ATS, we provide a "One-Stop Shop" for Bulgarian residential and industrial projects.
Custom laser marking, private labeling, and specific voltage calibrations for Bulgarian grid requirements.
Fully certified with CE, TUV, and ISO9001, ensuring seamless customs clearance and compliance in the European Union.
Our production environment adheres to 6S management principles, ensuring the highest level of cleanliness and efficiency for sensitive electronic components like Smart Reclosing Protectors and Overvoltage Sensors.
For standard MCB and SPD orders, our production lead time is 7-15 days. Shipping to the Port of Varna or Burgas typically takes 30-35 days via sea freight, or 7-10 days via air freight to Sofia Airport.
Yes, we manufacture specific 3-pole and 4-pole configurations designed for 1500V DC applications, which are becoming the standard for large-scale solar utility projects in Southern Bulgaria.
All products are CE marked. We can provide technical datasheets in English or Bulgarian and customize the packaging to include the necessary import information required by Bulgarian customs authorities.
Absolutely. We encourage technical validation. We can ship samples of our Photovoltaic DC MCB or WiFi Smart Switches directly to your facility for performance benchmarking.
