Explore our high-performance circuit protection devices and OEM components engineered for global B2B distribution.
Founded in 2015, Acereare Electric operates two wholly-owned subsidiaries, "RuiRui Electric" and "KeRui Electric". We are a professional original manufacturer integrating research, development, production, and sales. We specialize in molded case circuit breakers (MCCB), air circuit breakers (ACB), and precision stamping components.
Inheriting over 20 years of craftsmanship across two generations, our team possesses a deep technical accumulation and a mature production system. Today, we rank among the top ODM/OEM manufacturers in China, serving as a trusted supplier for major electrical brands globally.
Addressing modern electrical distribution challenges across new energy, smart grids, and heavy industrial automation environments.
The global transition to green energy demands robust circuit protection systems capable of handling elevated DC voltages. Solar photovoltaic (PV) plants operate at 1000VDC to 1500VDC to optimize transmission efficiency. Standard breakers cannot safely extinguish arcs at these levels.
Our ARM6DC series photovoltaic solar type DC MCCBs are engineered to address this. Incorporating optimized arc chutes, magnetic runners, and silver-alloy moving contacts, they ensure rapid fault isolation, minimizing the risk of thermal runaway in solar combiner boxes and central inverters.
Modern commercial and industrial facilities require more than simple overcurrent protection; they need real-time data. Intelligent breakers equipped with built-in microprocessors (like the ARM3E series with LSIG trip units) provide precise monitoring of voltage, current, power factor, and harmonics.
This edge-computing capacity integrates with Building Management Systems (BMS) and SCADA systems through Modbus or Ethernet protocols, enabling predictive maintenance, dynamic load shedding, and rapid troubleshooting, which reduces operational downtime.
B2B electrical distributors and panel builders require suppliers that offer high production capacity, strict quality compliance, and component customization. By manufacturing both final breakers and core parts (such as stamping molds, fixed contacts, and moving contact assemblies) in-house, we secure supply chain independence. This integration minimizes lead times and maintains consistent quality across high-volume wholesale orders.
Adhering to the value of mutual growth, we build strong partnerships with our B2B clients by providing reliable manufacturing, advanced engineering, and structured quality assurance.
We provide one-stop service leveraging six processing techniques. Our facilities feature high-precision production machinery, specialized testing instruments, and over 10 manual and automated assembly lines.
Our engineering team includes 50+ R&D professionals with over 5 years of experience. We develop parts, tooling molds, and complete assemblies in 3D CAD/CAE software, executing 50+ custom design projects annually.
Operating two manufacturing facilities, we scale production for components and assembled units. We synchronize workflow scheduling across departments using integrated ERP and U8 management software.
We implement a multi-stage inspection process supported by our internal test laboratory. Using over 150 testing instruments, our QC team manages quality parameters through PLM, BI, ERP, and MES software.
We design and manufacture a wide range of low and medium voltage protection apparatuses, tailored for specific utility and industrial configurations.
Our catalog includes thermal-magnetic and electronic breakers designed for high breaking capacities (up to 200kA Icu). Key series include:
Providing customized circuit protection solutions designed to maintain performance in extreme environments and demanding industrial scenarios.
Our cold-climate breakers utilize low-temperature resistant structural polymers and specialized non-freezing mechanical lubricants. Metallic parts receive a thickened anti-corrosive coating, verified by test reports down to -40°C.
Designed for docks, marine vessels, and coastal infrastructure, our MCCBs withstand humid, high-salinity air. We perform 72-hour salt spray testing on complete assemblies and 48-hour testing on sub-assemblies to verify corrosion resistance.
For installations exceeding 2,000 meters above sea level, thin air reduces dielectric properties and cooling efficiency. We calculate and apply specific high-altitude derating coefficients to modify insulation performance and thermal thresholds.
Our residential and commercial breakers protect appliances and branch circuits from overload and short-circuit damage. Compact designs allow for simple DIN-rail or panelboard installation while meeting local safety standards.
For environments up to 55°C, we utilize high-temperature resistant plastics, thermal isolation coatings, and moisture-resistant treatments on copper and iron elements to ensure stable operation without premature tripping.
Combining protection with precision metering, these systems support smart grids. Equipped with edge computing capabilities and communication modules, they allow operators to monitor energy consumption and circuit health remotely.

Our production facilities operate under ISO 9001, ISO 14001, and ISO 45001 management systems to guarantee compliance with regional grid codes.
Our R&D initiatives focus on sustainability, advanced digital integration, and higher voltage handling capabilities.
Traditional mechanical breakers rely on contact separation, which produces electrical arcs that erode metal contacts over time. Our engineering team is developing solid-state hybrid breaker prototypes. By combining semiconductor elements with low-resistance mechanical contacts, these units interrupt faults in microseconds, minimizing arcing and extending service life.
To reduce environmental impact, we are transitioning from thermosetting resins to recyclable, high-performance thermoplastics for breaker housings. These materials offer high mechanical strength and electrical insulation while allowing end-of-life recycling, helping partners meet sustainability requirements.
With the expansion of 5G infrastructure, smart cities require localized power systems with remote reset capabilities. We are expanding our micro-MCCB series with automated motor operators and IoT communication modules, allowing telecom providers and municipal grids to manage remote distribution points efficiently.
Addressing the technical, regulatory, and supply chain questions most relevant to B2B purchasers and electrical engineers.
