Explore our foundational range of moving contacts, thermomagnetic MCCBs, high-voltage breakers, and structural metal components designed for ultimate electrical grid dependability.
Modern industrial plants, mega data centers, and high-capacity commercial infrastructures require extremely robust fault isolation mechanisms. At the heart of these protection layers lies the Air Circuit Breaker (ACB) and the Molded Case Circuit Breaker (MCCB). These devices prevent catastrophic mechanical stress, thermal overloads, and electrical fires by isolating overload and short-circuit faults within milliseconds.
As global energy demands shift toward decentralized renewable microgrids (such as photovoltaic solar generators, wind turbines, and utility-scale battery energy storage systems), the operational voltage of distribution systems has surged from conventional 400V/690V networks up to 1000VAC, 1140VAC, and even DC environments. This requires circuit breakers capable of interrupting high fault currents under aggressive dielectric strain. Sourcing directly from certified, research-backed manufacturers is no longer just a purchasing tactic—it is a critical safety strategy.
Our research focuses heavily on optimizing arc quenching processes. By using proprietary silver-alloy and high-conductivity copper moving contacts combined with advanced ceramic arc chutes, our circuit breakers effectively partition and extinguish heavy electrical arcs inside the breaker chamber, preventing switchgear explosions.

A Dual-Subsidiary Synergy: RuiRui Electric & KeRui Electric
Established formally in 2015, Acereare Electric represents a 20-year manufacturing heritage passed down through two generations of electric power systems specialists. With two wholly-owned production subsidiaries, RuiRui Electric and KeRui Electric, we cover the entire supply chain. Our operations run from sourcing raw high-grade copper and steel, stamping and molding silver-alloy moving contacts, up to assembling complex electronic trip units and fully-rated ACB frames.
We have grown to become one of China's top well-known ODM manufacturers for switchgear distributors, engineering procurement contractors (EPCs), and industrial panel builders. We are trusted by more than 100 high-end domestic and global partners who depend on us for consistent product quality and reliable bulk deliveries.

Why global procurement leaders choose Acereare Electric as their long-term supply partner for electrical safety equipment.
One-stop production incorporating six core mechanical processing methods. We use high-precision metal stamping, tooling design, and automated assembly lines to turn raw materials into high-performance finished machinery.
Over 50 R&D engineers, each with 5+ years of experience, design custom electrical parts and molds. They manage over 50 new engineering projects annually using advanced 3D software simulation.
Two distinct factories separate components manufacturing and main assembly. We coordinate all operations via ERP and U8 management software to ensure delivery times match client expectations.
Over 150 testing instruments, 20 dedicated QA inspectors, and an in-house laboratory. Every step is tracked via PLM, BI, ERP, and MES software to confirm that each unit meets technical specifications.
Electrical networks operate in diverse, challenging conditions. We design and test our circuit breakers to handle these exact environmental extremes.
Tested down to -40℃. We build these units using cold-resistant structural materials, low-temperature lubricants, and thickened protective plating to prevent mechanical sticking in arctic or industrial cooling installations.
Our components undergo 72-hour salt spray tests for completed assemblies and 48-hour tests for sub-assemblies. This protects equipment on docks and ships from corrosion caused by moist, salty sea air.
At elevations above 2,000 meters, thinner air reduces cooling efficiency and dielectric strength. We provide high-altitude derating tables to adjust insulation levels and thermal ratings for safe operation.
Highly responsive protection against short circuits and overloads in appliances and buildings. These compact units offer convenient installation, modern design, and long-term mechanical reliability.
Designed using heat-resistant plastics and thermal insulation layers for controller components. High-conductivity copper parts prevent overheating, with performance verified in our 55℃ testing chamber.
Includes built-in edge computing, real-time current metering, and remote communication modules. This provides the feedback and remote diagnostics required for modern utility networks.
From micro-tripping components to massive draw-out air circuit breakers, discover the technical profiles of our flagship series.
The ARW1 series intelligent type ACB is applicable to AC 50Hz/60Hz distribution networks with rated operational voltages of 690V and below, and rated current coverage spanning 400A up to 6300A. Engineered to act as the primary inlet breaker for low-voltage switchboards, the ARW1 offers high-precision selective protection to avoid complete system shutdowns during minor localized faults.
It is equipped with a digital microprocessing unit that enables four remote communication functions: Remote Sensing, Remote Adjustment, Remote Control, and Remote Signaling. This makes it an ideal fit for automated control centers, smart industrial plants, and utility substations.
Standard and earth-leakage molded case circuit breakers providing vital residual current protection. Built for high breaking capacities in commercial installations and machinery plants.
Features adjustable thermal and magnetic trip thresholds. Offers reliable short-circuit protection for standard industrial motors and power distribution cables.
Microprocessor-driven molded case circuit breakers with LCD screens and adjustable LSIG trip units. Ideal for dynamic loads that require precise trip setting profiles.
We manufacture our own copper components and stamping plates rather than buying them from external vendors. Our factories utilize high-density oxygen-free copper and pure silver alloy contact tips. This structural approach ensures low internal contact resistance, minimizes thermal buildup during continuous duty, and extends the electrical life of the breaker.
Designed for demanding utility networks and power plant switches, the ARW3 heavy-duty series provides reliable short-time withstand current (Icw) protection. It maintains high insulation integrity under high-voltage spikes, ensuring long-term service life.
Understanding the strict compliance, volume logistics, and engineering specifications required by global industrial purchasers.
By producing critical components like moving contacts and stamping plates in-house, we reduce production margins. We pass these savings directly to switchgear manufacturers and distributors, helping them remain competitive in their local markets.
Operating two production plants allows us to manage manufacturing risks effectively. If one line requires scheduled maintenance or tooling updates, production is shifted to the parallel facility, protecting client delivery timelines.
We use ERP and MES software to manage quality control at every stage. From the incoming raw copper alloy batches to the final calibration tests of each electronic trip unit, every step is fully traceable.
The future of electrical safety lies in smart, predictive diagnostic systems. Modern air circuit breakers are evolving from simple mechanical switches into digital sensors. By monitoring contact wear, arc temperatures, and control voltage patterns, these smart breakers can predict mechanical faults before they occur.
We are currently developing smart breakers that integrate with IoT platforms via Modbus, Profibus, and Ethernet. This allows plant managers to monitor electrical loads and diagnostic data from any location, improving overall system safety and efficiency.
Additionally, we are focusing on environmental sustainability. We use lead-free materials, follow green packaging guidelines, and design for recyclability, aligning our products with international environmental standards like RoHS and REACH.
