High-performance MCCB components specifically customized to comply with European Standards (EN 60947-2) and Romania's energy retrofitting programs.
Romania has emerged as one of Central and Eastern Europe's key industrial hubs. Driven by significant investments in automotive manufacturing (Mioveni and Craiova clusters), massive metallurgical production in Galați, and the rapid deployment of solar and wind installations in Dobrogea, the local electrical distribution system is undergoing a comprehensive transition. Power quality and system resilience have become crucial criteria for engineering firms and plant managers.
The National Integrated Climate and Energy Plan (PNIESC) mandates substantial structural updates to grid reliability. For MCCBs and their respective accessories, this translates to strict compliance with European standard EN 60947-2. The demand is shifting rapidly from standard thermal-magnetic protection to smart electronic trip units (LSIG) with Modbus communications and durable plug-in components that facilitate rapid maintenance, minimizing industrial downtime.
Integrating R&D, manufacturing, and distribution, Acereare operates alongside its two wholly-owned subsidiaries, "RuiRui Electric" and "KeRui Electric".
With core technical expertise developed over 20 years by two generations of specialized electric craftsmen, the parent group was officially unified and registered in 2015. Our modern manufacturing base has established itself as one of the premier original equipment manufacturers (OEM) and original design manufacturers (ODM) in China.
By leveraging advanced supply chains and proprietary tooling labs, we produce air circuit breakers (ACB), molded case circuit breakers (MCCB), and a comprehensive catalog of internal and external accessories. We service industrial networks, utilities, and automation integrations in over 50 countries, with a primary focus on the infrastructural expansion of EU markets like Romania.

Optimizing protection performance across diverse environments, from harsh mountain winters to marine shipping docks.
Engineered with specialized low-temperature resistant polycarbonates and anti-freezing lubrication. Certified to operate reliably at temperatures down to -40°C, perfect for Carpathian wind farm nacelles and outdoor electrical cabinets.
Withstands marine corrosion through anti-corrosive copper coatings and passivated metal stampings. Subjected to 72 hours of intense salt spray testing, making it ideal for the Port of Constanța and Black Sea shipping infrastructure.
Adjusted for low air pressure situations above 2,000m. We integrate high-altitude derating coefficients to guarantee optimal insulation capability and prevent unwanted arc strikes in mountainous industrial zones.
High-precision overload and short-circuit protection for building main distribution frames. Designed to integrate auxiliary switch modules to transmit device status to main building management systems (BMS).
Engineered with thermal barriers and moisture-proof components tested at 55°C within constant-temp chambers. Perfect for demanding environments like glass factories and heavy metallurgical plants.
Enables real-time remote voltage, current, and energy consumption telemetry. Provides edge-computing protection triggers that support Modbus communication for smart municipal grid integrations.

Where is low-voltage power protection heading? Discover the upcoming integration models of smart hardware.
Transitioning to halogen-free, recyclable resins for all MCCB body parts and base shells, exceeding baseline EU RoHS directives to assist local Romanian facilities in lowering carbon footprint metrics.
Deploying integrated IoT-connected digital modules inside secondary auxiliary blocks. This enables real-time wear analytics and predictive maintenance models over standard Ethernet/IP links.
Prototyping hybrid solid-state circuit breaking units capable of interrupting microsecond overcurrent spikes, matching the strict demands of large utility solar farms across southern Romania.
Technical answers regarding standards, compatibility, configurations, and B2B ordering logistics.
Yes, all our molded case circuit breakers and corresponding accessories (auxiliaries, interlocks, shunt releases, motorized operations) are fully certified according to IEC/EN 60947-2 standards. We maintain comprehensive CE and RoHS documentation for all batches shipped to Romania.
Absolutely. For installations at elevations exceeding 2,000 meters (such as in the Carpathian mountain range), standard air cooling and insulation capacity are reduced. We supply specific high-altitude derating adjustment charts detailing changes in rated operational voltage (Ue) and thermal current (Ith).
Our auxiliary contact modules are engineered using top-grade silver alloy contacts, which provide reliable performance for up to 10,000 electrical operations and 20,000 mechanical operations under normal conditions, ensuring compatibility with PLC control circuits.
Complete devices are subjected to 72 hours of continuous salt spray testing according to IEC standard procedures, while individual internal metallic mechanism stampings are tested for 48 hours. This prevents corrosion in salty and humid coastal environments.
Standard custom production runs typically take 25 to 35 days, depending on tooling complexities. Sample custom prototypes can be expedited in 10-15 days. We coordinate directly with major shipping lines to optimize freight routes to Constanța Port or overland European transit hubs.
Our quality systems are run through integrated PLM, ERP, BI, and MES databases. Every unit produced receives a serialized quality profile, ensuring complete trace verification of components, assembly operator data, and final lab testing values.
Yes. Initial investments for custom mold fabrication and international certification tests are fully refunded or credited back to your account once your business meets the agreed-upon annual order volume targets.
