High-performance Air Circuit Breakers, Molded Case Circuit Breakers, and electrical distribution accessories direct from China's leading ODM smart factory.
Founded officially in 2015, Acereare Electric operates on a foundation built by two generations of craftsmanship over a span of 20 years. We control two wholly-owned subsidiaries, "RuiRui Electric" and "KeRui Electric", specialized in developing and manufacturing molded case circuit breakers (MCCB), air circuit breakers (ACB), and premium-grade internal components.
As a leading ODM partner in China, we manage comprehensive production chains from stamping to intelligent electronic calibrating systems, servicing globally-renowned brands in high-demand electrical sectors.
In low-voltage distribution systems, Air Circuit Breakers (ACBs) serve as the primary defensive shield, protecting power transformers, generators, and distribution networks from excessive currents, thermal overloads, and ground faults. As modern electrical infrastructure transitions toward smart grids and distributed energy systems, the technical criteria for selecting an air circuit breaker manufacturer has shifted from basic thermal-magnetic tripping mechanisms to high-precision microprocessor-based protection systems that offer comprehensive communication capabilities.
Historically, ACBs utilized mechanical delay systems to handle overcurrents. Today, intelligent air circuit breakers feature digital controllers capable of real-time root-mean-square (RMS) current measurement, harmonic analysis up to the 31st order, and directional protection schemes. Under standard industrial applications, these breakers operate on distribution networks up to 690V and currents ranging from 400A to 6300A. A notable example is the ARW1 series intelligent type ACB, which offers dual-break contact structures, fast-acting arc extinction systems, and advanced communications protocols including Modbus, Profibus, and Ethernet/IP.
"The incorporation of the 'Four Remote' functions—remote sensing, remote adjustment, remote control, and remote signaling—allows industrial operations to integrate their main incoming breakers directly into centralized SCADA platforms, reducing downtime by up to 45%."
Procurement directors face a dual challenge: maintaining strict safety compliance (IEC/EN 60947-2, CE, CB) while managing volatile component costs. Chinese factories have transitioned from simple component assemblers to advanced automated manufacturers. By vertically integrating raw material processing—such as silver contact welding, thermosetting plastic molding, and copper stamping—they mitigate risks of raw material price hikes and secure consistent supply chains for global buyers.
Global EPC contractors choose Chinese suppliers not only for cost efficiencies, but also for their rapid response times in customizing trip curves, auxiliary contact configurations, and physical mounting solutions (such as draw-out vs. fixed execution bases).
We deploy advanced testing laboratories, digital enterprise resource planning (ERP), and manufacturing execution systems (MES) to maintain zero-defect standards.
One-stop production incorporating six core processing techniques. We operate high-precision fabrication equipment alongside more than 10 manual and automated assembly lines to guarantee batch stability.
Our team of over 50 R&D engineers uses advanced 3D software for part design and mold optimization, delivering more than 50 research and development projects yearly to meet local regulations.
With two manufacturing plants producing internal copper/stamping components and finished machines, we integrate operations through U8 ERP platforms to secure components and deliver orders on time.
We perform multi-step quality control using an in-house laboratory equipped with 150+ testing instruments. Quality metrics are tracked using integrated PLM, BI, and MES platforms.
Our breakers are designed and tested to withstand high altitudes, severe humidity, low temperatures, and smart measurement needs.
Built with low-temperature resistant structural plastics and specialized lubricating oils. All mechanical linkages are treated with thickened protective coatings. Verified with low-temperature test reports at -40 ℃.
Our breakers withstand 72-hour salt spray testing for complete units and 48 hours for sub-assemblies. This protection prevents corrosion in dockside systems, protecting motors and transformers near the sea.
For installations above 2000m, air density and heat dissipation properties change. We calibrate the electrical performance of our circuit breakers using specialized high-altitude derating tables.
ACBs and MCCBs safeguard household and commercial networks against overloads and short circuits. These systems are designed to provide operational flexibility and high service reliability.
Equipped with heat-resistant materials and thermal barrier coatings on controllers. Copper and iron parts are treated to resist humidity. Certified via testing in our 55 ℃ constant-temperature laboratory.
Integrating communication, metering, protection, and edge computing. These breakers protect circuits, provide high-precision energy measurement, and support multiple communication protocols for smart grids.
Partnering with more than 100 global high-end customers to supply branded distribution equipment and high-quality internal parts.
Our production facilities operate under ISO 9001, OHSAS 18001, and ISO 14001, ensuring our products comply with international safety and quality standards.
