Explore our core engineering portfolio of high-performing circuit protection systems designed for critical applications.
In modern industrial infrastructure, electric power forms the central nervous system. Achieving efficient, scalable, and safe distribution systems requires robust circuit breakers rated to survive thermal and electrical loads across a multitude of operating conditions. Voltages ranging from 400V up to 690V represent the core foundation of industrial machinery, grid-scale renewable generation, and heavy manufacturing. As a leading global wholesale supplier of voltage-specific circuit protection architectures, Acereare Group provides the technical expertise and high-breaking capacities (up to 200KA Icu) needed to withstand severe fault events while ensuring operational continuity.
The global transition to renewable sources—specifically high-power industrial wind turbines and centralized photovoltaic systems—has fundamentally altered the demands placed on distribution grids. In wind turbines, generation voltages are frequently optimized at 690V AC to minimize line losses across the turbine tower structure, necessitating Molded Case Circuit Breakers (MCCBs) and Air Circuit Breakers (ACBs) that can guarantee absolute trip reliability under rapid load variations. Traditional power grids require predictable protection architectures; modern smart networks demand highly adaptable, electronically controlled MCCBs featuring LSIG (Long, Short, Instantaneous, Ground) protection parameters to achieve dynamic selectivity without spurious tripping.
Ensuring fault selectivity within deep electrical distributions is the key to preventing widespread outages. If a fault occurs at a local load terminal, upstream breakers must remain closed while the local breaker isolates the issue. Through strict synchronization of current-limiting profiles and high short-circuit withstand values, our design configurations eliminate cascading failures. Our ARM5 series offers extreme thermal-magnetic resilience up to 200KA, allowing electrical designers in data centers, heavy industrial complexes, and marine installations to confidently map out safe, selective networks.
Founded in 2015, Acereare Electric has built an outstanding industry footprint, expanding to include two wholly-owned manufacturing subsidiaries: RuiRui Electric and KeRui Electric. Operating as a professional, vertically integrated original equipment manufacturer (OEM) and original design manufacturer (ODM), we manage the entire lifecycle of our circuit breakers—from core metallurgy and component tooling to advanced automated final assembly.
Our operation is built on over 20 years of technical expertise passed down through two generations. Officially establishing RuiRui Electric in 2015 marked a new era of industrial-scale R&D and advanced testing facility upgrades. Today, Acereare ranks as one of the top ODM manufacturers in China, recognized for high-volume supply capabilities, robust engineering, and direct factory pricing.
Acereare manages two specialized factories dedicated to production scaling, mechanical part stamping, electrical contacts molding, and complete breaker calibration:
Adhering to our core value of win-win cooperation, we have built a solid reputation among our global customers for outstanding service, first-class products, and unbeatable direct manufacturer pricing.
One-stop processing across six production methods. Utilizing high-precision equipment, testing instruments, and more than 10 specialized assembly lines.
Over 50 dedicated R&D engineers with 5+ years of design experience. Highly skilled in 3D design of molds, complex components, and finished systems, completing 50+ projects annually.
Operating two production facilities to scale up raw material components and final assembly. Streamlining operations via advanced ERP and U8 business software.
Rigorous testing and inspection inside our specialized laboratory, featuring 150+ measurement instruments and 20+ QC inspectors tracking data via PLM, BI, ERP, and MES systems.
Industrial installations present varied operational challenges. Our components are custom-engineered for maximum resilience in extreme conditions.
Utilizing high-impact, low-temperature resistant polymers and low-friction lubricants, our components retain mechanical speeds in cold climates. Verified by our certified -40°C performance reports, they prevent binding and cracking in outdoor polar substations.
Built for ports, coastal infrastructure, and marine shipping. Our systems withstand 72-hour complete system and 48-hour sub-assembly salt spray cycles. Silver-plated mechanical components resist moisture and coastal air, protecting dockside cranes and vessel power boards.
Operating above 2,000 meters requires specific configuration adjustments due to reduced air density. Decreased dielectric strength and lower convective cooling are corrected using precise derating tables, ensuring consistent tripping calibration at high altitudes.
Our MCCB systems are widely utilized in commercial real estate and smart home networks, shielding end-user lines from surges and thermal overloads. Compact dimensions and flexible modular rail installations simplify integration into distribution boards.
Tested inside our 55°C constant-temperature rooms. Circuit contacts and housings are protected by heat-mitigating barriers, while iron and copper parts feature moisture, corrosion, and heat-resistant plating to ensure stable operation in hot industrial sites.
Equipped with built-in micro-processors, our breakers enable remote communication, power metering, and status control. Supplying accurate grid telemetries via standard communication protocols, they serve as core sensors for smart energy systems.
A reliable supplier accelerates market entry, builds brand trust, and secures competitive pricing advantages.
Evaluating detailed system voltage levels and regional grid requirements.
Mapping trip curve settings and selecting frame sizes.
Finalizing specifications, delivery schedules, and contracts.
Coordinating quality checks across manufacturing lines using ERP/PLM tracking.
Dispatching cargo worldwide with complete packaging and documentation.
Acereare Group supplies a complete selection of molded case and air circuit breakers designed for critical electrical networks. Our product lines include the ARM1, ARM1L, ARXM3, ARM3E, ARM5, and ARM6 series, along with a wide range of MCCB components.
The ARW1 series intelligent type ACB is designed for AC 50Hz distribution networks with rated operational voltages of 690V and below, spanning rated current lines from 400A to 6300A. The ARW1 delivers high-precision selective protection to ensure system reliability. Equipped with an open communication interface, the ARW1 supports four remote functions: "remote sensing", "remote adjustment", "remote control", and "remote signaling", fully meeting the requirements of automated control centers.
All Acereare factories run strict quality verification processes to meet global industrial standards.
As the electrical distribution landscape continues to evolve, our R&D teams focus on developing technologies designed to integrate with tomorrow's smart grids. Future power distribution calls for faster fault isolation and seamless communication with cloud-based management systems.
To support microgrids and renewable energy systems, we are engineering solid-state and hybrid circuit breakers. By using semiconductor switching instead of traditional mechanical separation, these components isolate faults within microseconds, protecting sensitive electronics from transient overvoltages.
Our upcoming product lines will expand on standard Modbus systems to include cloud-connected IoT interfaces. These smart breakers collect real-time data on contact temperatures, mechanical wear, and power quality, feeding it directly to central monitoring software. This allows operators to schedule predictive maintenance before faults occur, reducing costly industrial downtime.
In line with global eco-friendly standards, Acereare is incorporating recycled and halogen-free thermoplastics into our breaker housings. Our design engineers work to reduce internal resistance, lowering power losses and thermal emissions during operation to support green energy targets.
