Founded officially in 2015 and inheriting over 20 years of craftsmanship spanning two generations, Acereare Electric stands as a premier original design and equipment manufacturer (ODM/OEM) in China's low-voltage electrical capital. Specializing in molded case circuit breakers (MCCB), air circuit breakers (ACB), and intricate switchgear components, our operation delivers vertically integrated production from raw metal stamping to automated calibration.
By leveraging two modern manufacturing bases (Ruirui Electric for raw component precision and Kerui Electric for automated assembly & QA testing), we service strategic partners across more than 40 countries, establishing ourselves as the cornerstone supplier for prominent global power brands.
Understanding the operational advantages that make Chinese circuit breaker manufacturing cost-effective without sacrificing durability.
We provide a comprehensive, one-stop service encompassing six unique metal and polymer processing techniques. Our facility is equipped with automated stamping presses, high-precision injection molding machinery, and CNC component tooling lines, maintaining tight mechanical tolerances.
Our engineering wing houses 50+ designers experienced in 3D CAD modeling, structural finite element analysis (FEA), and thermodynamic arc simulation. Annually, we launch over 50 customization projects, adapting standard MCCB frames to bespoke enclosure configurations.
By owning both component sub-factories and final assembly plants, we mitigate third-party supply chain shocks. Operation management is fully integrated through U8 and ERP business suites, ensuring traceability and delivery consistency.
Quality checks are embedded throughout the assembly process. With 150+ dedicated calibration instruments, 20+ specialized inspectors, and integration across PLM, BI, and MES platforms, every individual circuit breaker's test data is archived.
Acereare's comprehensive product lineup spans from compact residential units to massive industrial air circuit breakers.
The ARW1 series intelligent type Air Circuit Breaker (ACB) is designed for AC 50Hz/60Hz distribution networks with a rated operational voltage ($U_e$) up to 690V and rated currents spanning 400A to 6300A.
Engineered for switchgear entry points, the ARW1 features high-precision selective micro-processing trip units that allow full parameterization of long-time delay, short-time delay, and instantaneous fault curves (LSIG). An integrated open communication interface supports Modbus-RTU protocol, enabling "remote sensing", "remote adjustment", "remote control", and "remote signaling" within smart grid automation networks.

How our custom-tailored circuit breakers withstand severe environmental, atmospheric, and telemetry demands.
Utilizing low-temperature resistant polyamides and specialized internal lubricants, our custom breakers maintain trip sensitivity and spring mechanism mechanical elasticity in extreme sub-zero climates.
Built for ports, coastal infrastructure, and marine environments. Machine shells survive 72 hours, and sub-assemblies endure 48 hours of continuous salt mist exposure, preventing rust formation on structural parts.
For installations exceeding 2000 meters, we supply precise technical derating factor tables. The designs account for thin air insulation breakdown and diminished thermal heat dissipation.
We supply modular, safe, and easily integrated miniature and molded-case circuit breakers for commercial and residential power distribution boards, emphasizing physical compact sizing and silent tripping.
Configured with heavy-duty heat-dissipating copper paths and high-temp glass fiber reinforced housings. All trip curves are calibrated inside specialized constant-temperature testing rooms.
Features embedded current transformer modules and digital microchips. These MCCBs track active power metrics, report harmonics, and output data via Modbus/LoRa protocols for industrial edge-computing.
Acereare Electric does not just assemble components. We offer end-to-end electrical design, validation, and optimization services. Our factories handle structural modeling, injection molding, metal stamping, and automatic thermal calibration under one roof, keeping production times predictable.
Whether you require a custom branded housing for your distribution panels or specialized breaking capacities for solar utility applications, our engineering team is structured to deliver fast prototypes and certified bulk production.
• Custom brand logo laser engraving on breaker frames.
• Tailored packaging design including inner packaging boxes, user guides, and master cartons.

How we ensure seamless transitions from client concepts to final mass production.
Acereare's manufacturing processes conform to international standards, verified by recognized testing laboratories.
As smart power grids and sustainable energy systems expand, the demands on low-voltage protective devices are shifting. Conventional thermal-magnetic mechanisms are giving way to solid-state digital tripping devices. Acereare is at the forefront of this evolution by incorporating alternative contact materials, arc chamber telemetry, and IoT diagnostics.
1. Eco-Conscious Thermoplastics: Modern regulatory frameworks like RoHS and REACH demand the elimination of halogenated flame retardants. We are migrating our housing moldings to bio-based polyamides that deliver comparable thermal stability and arc containment without environmental hazards.
2. Solid-State Breaking (SSCB): By eliminating moving copper contacts, solid-state circuit breakers interrupt currents in microseconds, virtually eliminating arc flashes. We are actively prototyping hybrid digital switches that combine physical isolation with semiconductor safety triggers.
3. Harmonic Analysis & Current Profiling: Non-linear power loads from EV charging stations and solar inverters introduce harmonics into industrial power networks. Our intelligent ARM3E & ARW1 controllers monitor these anomalies in real-time, helping plant operators execute predictive maintenance before faults occur.
