Acereare Electric: Two generations of electrical expertise driving structural safety and intelligence in circuit protection.
Acereare Electric, founded in 2015, proudly operates two wholly-owned subsidiaries: "RuiRui Electric" and "KeRui Electric". We are a professional original equipment manufacturer (OEM/ODM) integrating R&D, production, and sales. We specialize in low-voltage electrical protection solutions, particularly Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and high-precision core components.
With over 20 years of craftsmanship inherited by two generations, our industrial history began long before our formal registration in 2015. Backed by deep technical experience, vertical supply chain integration, and a sophisticated production system, our factories rank among the top ODM partners in China for low-voltage power distribution equipment.
Adhering to our core value of win-win cooperation, we have built a solid reputation for reliable quality, integrated supply capacity, and optimal structural design.
One-stop service across 6 distinct processing technologies. Powered by high-precision stamping, moulding, and testing instruments, alongside 10+ manual and automated production lines.
Over 50 dedicated R&D engineers with 5+ years of design experience. Highly proficient in 3D CAD modeling, structural finite element analysis, and electrical simulation, executing 50+ new projects annually.
Owning two massive component and assembly factories ensures vertical supply stability. Integrated production scheduling and quality controls are managed seamlessly via ERP and U8 software.
Multi-step inspection workflows backed by our own component laboratory. Utilizing over 150 testing instruments, 20+ specialized QC inspectors, and digital PLM/BI/ERP/MES tracing systems.
A comprehensive look at industrial power system design, safety requirements, and engineering considerations for low-voltage power distribution networks.
In main electrical distribution systems, Air Circuit Breakers (ACBs) serve as the primary defensive mechanism against severe electrical fault conditions, including high-magnitude short circuits, ground faults, and sustained overloads. Unlike smaller protection devices, an ACB must manage extreme thermal and electrodynamic stresses. It is engineered to disconnect high currents safely—often exceeding 50kA to 100kA—while maintaining operational integrity. Utilizing air as the arc-extinguishing medium, these breakers guide the electrical arc into specialized steel arc chutes. These chutes split, cool, and extinguish the arc within milliseconds to prevent damage to downstream switchgear.
Choosing a Chinese supplier offers significant strategic advantages, particularly due to the deep integration of the local supply chain. The Liushi region in Zhejiang, China, serves as a global hub for low-voltage electrical components. This proximity allows factories like Acereare to secure high-purity electrolytic copper for busbars, advanced silver-alloy contacts, and high-performance fiberglass-reinforced molding plastics at optimal cost-to-performance ratios.
By producing stamping parts, contacts, and molded enclosures in-house, Chinese factories reduce manufacturing bottlenecks. Integrated ERP systems link local sub-contractors with the main assembly line, allowing for faster response times, highly customizable engineering adjustments, and predictable delivery schedules. This vertical supply integration makes Chinese manufacturing a reliable partner for global engineering projects.
The low-voltage electrical industry is shifting rapidly toward intelligent, digitally integrated solutions. Modern Air Circuit Breakers are no longer passive tripping devices; they function as core sensor nodes in smart factory systems. Key trends shaping the industry include:
Our portfolio spans high-performance circuit breaker systems designed for industrial safety and automated control.
The ARW1 series intelligent type ACB is designed for AC 50Hz/60Hz distribution networks with rated operational voltages of 690V and below, and rated currents ranging from 400A to 6300A. These units are built to provide highly reliable selective protection, helping to prevent broad network outages during localized fault events. Equipped with an open communication interface, the ARW1 supports the four remote functions: "remote sensing," "remote adjustment," "remote control," and "remote signaling." This makes it ideal for seamless integration into modern automated control systems and industrial smart grids.
Complementing our ACB lineup, we manufacture a wide range of Molded Case Circuit Breakers (MCCB), including the ARM1, ARM1L, ARXM3, ARM3E, ARM5, and ARM6 series. Because we control the manufacturing process down to the stamping and molding stages, we supply essential accessories like moving contacts with silver plating, copper connection plates, and high-durability busbars. This commitment to component-level quality ensures our circuit breakers deliver reliable, long-term performance under demanding industrial conditions.
Our engineering team designs customized protection solutions to meet the unique challenges of diverse operating environments.
We utilize low-temperature resistant materials and specialized low-temperature lubricants, combined with thickened structural coatings. Verified by laboratory test reports down to -40℃.
Designed to withstand humid coastal air and salt spray, with testing of 72 hours for complete machines and 48 hours for semi-complete assemblies. Ideal for dock power systems protecting motors and transformers.
For installations above 2000m, electrical properties are adjusted using a high-altitude derating table. This compensates for lower atmospheric density, ensuring reliable dielectric performance and heat dissipation.
Our compact MCCB solutions protect residential networks and household appliances from damage caused by overloads or short circuits, offering flexible installation and high operational reliability.
Built with high-temperature resistant materials, thermal insulation coatings, and anti-corrosive copper/iron components. Performance is verified in our constant-temperature testing chamber at 55℃.
Integrates protection with communication, metering, control, and edge computing. Delivers high-precision metering and supports major communication protocols for modern smart grid applications.
