Explore our industrial-grade Molded Case Circuit Breakers, components, and intelligent Air Circuit Breakers manufactured to strict IEC compliance.
Founded in 2015, Acereare Electric operates on a foundation of deep craftsmanship inherited through two generations of dedication. Operating two wholly-owned subsidiaries—RuiRui Electric and KeRui Electric—we manage a comprehensive ecosystem focused on the design, validation, and manufacturing of premium Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and structural components. Our position as a premier ODM and OEM supplier in China is validated by our integration of vertically aligned technologies from metal stamping to intelligent trip calibration.
A comprehensive examination of electrical safety, trip units, and mechanical configurations essential for critical distribution networks.
Our ARXM3 series uses reliable thermal-magnetic trip units, ensuring excellent short-circuit and overload protection. For advanced requirements, the ARM3E series utilizes microprocessor-controlled LSIG trip units, offering adjustable trip curves and communication interfaces for energy monitoring and selectivity.
We supply solutions for harsh systems, including solar-specific designs supporting 800VAC, 1000VAC, and up to 1140VAC. High-breaking capacities are verified by internal and external laboratory validations, offering reliability under fault currents.
By stamping and molding copper busbars, contacts, and metal parts in-house, we control mechanical tolerances. This vertical integration keeps operating temperatures low, contact resistance minimal, and product longevity high.
How our engineering, production, logistics, and quality assurance divisions integrate to deliver high-performance circuit protection.
Our facility offers a complete production process including metal stamping, plastic molding, spot welding, assembly, and thermal calibration. With high-precision equipment and more than 10 manual and automated assembly lines, we ensure high quality at scale.
Our team consists of more than 50 R&D engineers, each possessing over 5 years of industry experience. Using 3D CAD modeling software, we manage over 50 product designs, custom modifications, and mechanism optimization projects annually.
Operating two production plants, we balance standard component production with final device assembly. Every project is coordinated through integrated ERP and U8 software to maintain accurate scheduling and trace raw material origins.
Our quality control process is managed via PLM, BI, ERP, and MES software. Supported by an in-house laboratory housing over 150 testing instruments, our inspectors perform rigorous validation checks on incoming and outgoing components.
Our 320 Amp Molded Case Circuit Breakers are designed to withstand challenging physical and environmental conditions.
Utilizing low-temperature resistant polycarbonates, specialized low-viscosity mechanism lubricants, and thickened protective plating, our breakers operate safely in sub-zero mining, oil, and gas facilities.
We test our completed assemblies for 72 hours and internal components for 48 hours in salt spray chambers. This protects our MCCBs from offshore moisture and marine environments, making them suitable for ports and docks.
For installations above 2000 meters, we provide clear correction coefficients. These calculations address lower air density, adjusted cooling factors, and reduced dielectric properties, ensuring reliable operation at altitude.
Acereare breakers protect commercial buildings and large household distribution boxes, offering circuit protection to prevent fire and electrical damage under overload or short-circuit events.
We test our MCCBs in 55°C constant-temperature chambers. Using thermal-resistant materials and moisture-proof, corrosion-resistant components, our breakers operate reliably in hot industrial spaces.
Integrated microprocessors offer real-time power quality measurement, telemetry, and edge-computing diagnostics. They support Modbus and modern bus architectures to enable smart grid communication.
Whether you require laser engraving, customized enclosures, or complete electrical redesigns, we provide comprehensive product support.
Enhance market presence with customized brand logos, high-grade base materials, rapid sample creation, and structural configurations designed to differentiate your products.
Utilize our production lines with mold design development, custom electronic trip mechanisms, international compliance reports, and 24-hour response support.
Acquire specialized circuit breaker designs with laser-marked labeling, custom-printed packaging, customized catalogs, and low minimum order quantities (MOQ).
Our quality management systems and electrical products are tested and certified by international laboratories.
From low-current components to high-power distribution lines, we manufacture robust circuit protection devices.
Designed for rated distribution voltages up to 690V and currents ranging from 400A to 6300A (50Hz). Featuring digital protection controllers, these units maintain high selectivity and supply continuity. Supported communication links allow remote telemetry, monitoring, adjustment, and configuration via central SCADA networks.
Our product lineup includes multiple specialized series engineered to meet diverse operating requirements:
Important criteria for electrical engineers, distributors, and procurement managers when sourcing 320A MCCBs from Chinese factories.
Ensure the rated ultimate short-circuit breaking capacity (Icu) matches or exceeds your system's prospective fault current. Additionally, check that the service breaking capacity (Ics) meets application requirements.
For complex installations, specify electronic trip units with adjustable L, S, I, and G parameters. This allows for precise selective coordination and helps prevent unnecessary upstream breaker tripping.
Verify that your supplier provides valid IEC 60947-2 and CE test reports. For solar power systems, confirm the DC ratings of the insulation, contacts, and arc chutes to ensure safe operation at elevated voltages.
