Explore our premium-tier circuit breakers engineered for critical power distribution networks and harsh industrial environments.
An Elite ODM/OEM Industrial Circuit Breaker Manufacturer Built on Decades of Precision
Acereare Electric, founded in 2015, owns two wholly-owned production subsidiaries: "RuiRui Electric" and "KeRui Electric". We operate as a professional, vertically integrated manufacturer specializing in Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and premium copper/metal stamping components. Rooted in over 20 years of manufacturing craftsmanship inherited across two generations, our operation has scaled into one of China’s most prominent ODM factories for low-voltage power distribution equipment.
Our engineering ecosystem links state-of-the-art testing laboratories with advanced production systems. We maintain strategic alliances with nearly 100 high-end domestic and global B2B clients, helping power grids, manufacturing complexes, and renewable energy sites deliver safe, stable, and highly continuous electrical feeds.
Discover how our structural capacity, research team, and supply networks guarantee unbeatable product reliability.
We provide a one-stop industrial service featuring six proprietary metal processing techniques, high-precision stamping equipment, automated calibrations, and over 10 manual and automated assembly lines.
Our team of 50+ R&D engineers brings over 5 years of domain experience. We design specialized components, dies, and comprehensive switchgears in 3D CAD platforms, delivering 50+ new projects annually.
Operating two production hubs enables concurrent processing of raw materials, stamping parts, and finished circuit breakers. Resource scheduling is managed via ERP and UFIDA U8 networks.
We feature an in-house laboratory housing 150+ sets of testing instruments and 20+ specialized QC inspectors. Product compliance is tracked and managed continuously through PLM, BI, ERP, and MES software.
Explore how Acereare Electric integrates precision stamping, automated testing, and assembly.
Our commitment to engineering excellence is visible in our processing steps. From raw steel coil and copper bars to finished smart circuit breakers, we control every single phase. This integration allows us to keep tolerances tight, customize dimensions for OEM customers, and guarantee high interruption ratings (up to 200kA) across our entire catalog.
By leveraging intelligent management software, we log real-time test data for magnetic trip calibration, thermal testing, and mechanical endurance, ensuring complete product traceability.
Why sourcing from our specialized Wenzhou-based industrial complex yields immediate market advantages.
Based in the heart of China’s electrical capital, our facilities enjoy instant access to raw copper smelting, high-grade engineering plastics (such as glass-fiber reinforced polyamide), silver contact manufacturing, and mold tooling. This industrial proximity reduces shipping costs and keeps raw material lead times under 48 hours.
Because we stamp our own components (busbars, moving contacts, terminal connectors), we eliminate typical markups. Additionally, our high-volume purchasing contracts allow us to lock in competitive pricing for precious raw materials like copper and silver, passing these savings directly to our wholesale partners.
Unlike Western manufacturers with rigid, unalterable design catalogs, our engineers customize trip values, terminal geometries, housing dimensions, and auxiliary accessories. We turn CAD concepts into functional prototypes within weeks, accelerating your market entry.
Robust protection topologies engineered for extreme environments, heavy industry, and next-generation power infrastructure.
Modern solar installations (PV) and Battery Energy Storage Systems (BESS) require high-voltage DC protection. Our specialized DC Molded Case Circuit Breakers (up to 1500VDC) reliably interrupt high-energy DC arcs. These breakers prevent thermal runaways, isolate fault branches in solar combiners, and support smart bidirectional grids.
Heavy machinery, mining equipment, and metallurgical smelters cause high inductive load spikes and severe harmonics. Acereare’s high-capacity MCCBs (tested up to 200kA breaking capacity) protect these vital assets against high short-circuits. Built-in adjustable electronic trip units (LSIG) minimize unnecessary shutdowns.
To reduce carbon footprints, modern commercial centers require active power monitoring. Our smart measurement circuit breakers integrate edge-computing microchips. They monitor current, voltage, active power, and temperature in real-time, sending data to building automation systems via Modbus, RS485, or wireless channels.
Our circuit breakers undergo rigorous verification tests to ensure flawless operation under extreme thermal, chemical, and physical stress.
We utilize specialized, low-temperature resistant structural resins, premium low-viscosity mechanical oils, and thickened anti-freeze coatings. All low-temperature series breakers are certified in our environmental chambers to ensure mechanical trip mechanisms function down to -40 °C.
Engineered for marine installations, dockyards, and offshore wind platforms. Our components undergo 48 hours of salt spray testing, and complete assemblies endure 72 hours. This prevents corrosion on copper connections and iron springs, ensuring reliable operation near coastal and marine areas.
At high altitudes, thin air reduces heat dissipation and dielectric insulation. We apply specialized high-altitude derating coefficients to adjust operational voltages and currents, maintaining arc containment and heat management up to 5000 meters.
Engineered for residential complexes, our compact MCCBs isolate short-circuits and overloads. Their compact profile allows easy integration into domestic consumer units, enhancing safety and preventing fires.
Designed for hot industrial environments, like steel mills or desert installations. We use heat-resistant composites and thermal barriers. The copper and iron elements are treated to prevent oxidation, and performance is verified up to 55 °C.
Equipped with microcontrollers and current transformers, these units offer communication, high-precision power metering, overload protection, and remote control. They form the backbone of modern smart grids and automated industrial systems.
Discover our core series of high and low voltage circuit breakers designed for diverse application areas.
Designed for AC 50Hz networks with voltages up to 690V and currents from 400A to 6300A. It provides high-precision protection and includes an open communication interface. This enables remote sensing, adjustment, control, and signaling, meeting the requirements of automated control centers.
An electronic molded case circuit breaker supporting currents up to 1250A. It features a built-in LSIG (Long-time, Short-time, Instantaneous, Ground-fault) trip unit. This allows engineers to customize trip curves, ensuring precise protection and minimizing nuisance tripping.
A specialized DC circuit breaker designed for solar installations, supporting voltages of 700VDC, 1000VDC, and 1500VDC at currents up to 250A. Available in 2-pole and 4-pole configurations, it safely extinguishes high-voltage DC arcs, protecting solar arrays and storage systems.
We supply precision-engineered copper busbars, moving contacts, terminal connectors, and connection plates. These are manufactured using high-speed stamping presses and automatic riveting to ensure low electrical resistance and long service life.
Ensuring compliance with international standards to streamline importing, installation, and field deployment.
For B2B procurement managers and electrical wholesalers, safety compliance is paramount. Acereare Electric designs and tests its products in accordance with global electrical standards, including:
To support high-volume global distribution, we provide comprehensive documentation, including type-test reports, temperature rise charts, and derating tables. Our supply chain utilizes ERP and PLM systems to manage part numbers, revisions, and shipping logistics, helping to keep your inventory organized and prevent delays.
