Reliable electrical protection solutions for distribution, commercial networks, and power systems.
A legacy of electrical protection manufacturing and technology.
Founded in 2015, Acereare Electric operates through its two wholly-owned manufacturing subsidiaries: "RuiRui Electric" and "KeRui Electric". We are a professional original equipment manufacturer specializing in the research, development, production, and distribution of high-quality Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and structural copper components.
Our craftsmanship spans over 20 years, inherited across two generations of engineering leadership. Ruiru Electric, formally registered in 2015, marked a new era of modernization. With a solid technical foundation, advanced production systems, and integrated management, our facility is recognized as a leading ODM/OEM supplier of circuit breakers in China.
Through close strategic cooperation with nearly 100 high-end domestic and international clients, we deliver electrical components engineered for efficiency, resilience, and reliability.
Engineered circuit breakers customized to perform under challenging environmental and operational conditions.
Our circuit breakers utilize low-temperature resistant structural materials and specialized lubricant formulas. Moving metal parts receive targeted, high-thickness protective coatings. Certified by formal testing laboratories, these units ensure reliable interruption and operations down to -40℃.
Designed for damp, marine atmospheres, ports, and dock power systems. We execute rigorous environmental testing: 72 hours of salt spray exposure for complete assemblies and 48 hours for key modular sub-assemblies. This protects switchboards, motors, and line transformers from accelerated oxidation and moisture degradation.
At operating elevations exceeding 2000 meters above sea level, dielectric properties and convective cooling capacity decrease. We apply specialized correction coefficients to adjust rated operational current (Ie) and power-frequency withstand insulation parameters, securing stable operations in mountainous terrain.
Designed for compact space consumption and safe consumer integration. Our residential molded case breakers provide high mechanical durability and rapid arc-extinguishing performance to shield domestic networks, high-power HVAC circuits, and distribution boards from short circuit hazards.
Developed for hot desert climates, steel factories, and machinery yards. The shell structure utilizes high-temperature thermosetting resins, while critical internal conductors feature anti-corrosive, heat-mitigating plating. Tested in our constant 55℃ environmental chamber to guarantee structural integrity.
These advanced models integrate protection, metering, communication, and edge computing. Providing precision telemetry, they interface with SCADA networks using various communication protocols. This enables real-time voltage monitoring, power quality analysis, and automatic fault isolation.
Integrated manufacturing and advanced technical capabilities under one roof.
Our production workflow is managed internally across two specialized factories. This structure handles raw copper component stamping, precision terminal machining, plastic injection molding, and final product calibration. With over 10 manual and automated assembly lines, we optimize material flows, control lead times, and maintain supply chain resilience during demand peaks.
Backed by a team of over 50 electrical and structural design engineers, we execute more than 50 R&D projects annually. Leveraging 3D CAD modeling, structural finite element analysis (FEA), and mold-flow systems, we accelerate the journey from initial conceptualization to operational prototype testing.
To coordinate production schedules and material requirements, we deploy ERP and U8 software systems. This setup connects our sales forecasts, raw material stocks, metallurgical testing schedules, and shipping departments, minimizing bottlenecks and keeping delivery commitments on track.
Quality control is managed through integrated PLM, BI, ERP, and MES software. Our specialized laboratory houses over 150 test instruments operated by 20+ quality assurance inspectors. We conduct mechanical endurance tests, short-circuit interruption testing, and thermal calibration checks on every production batch.
A breakdown of our air circuit breakers and molded case circuit breaker options.
The ARW1 series intelligent ACB is designed for distribution networks operating at AC 50Hz, with rated voltages up to 690V and currents ranging from 400A to 6300A. It provides high-precision selective protection to ensure system reliability and prevent localized faults from causing widespread outages.
Equipped with open communication modules, it supports four key remote functions: "remote sensing," "remote adjustment," "remote control," and "remote signaling." This allows integration with centralized automation systems and industrial control networks.
| Circuit Breaker Series | Rated Operating Voltage (Ue) | Rated Current Range (In) | Number of Poles | Trip Unit Options |
|---|---|---|---|---|
| ARW1 Series (ACB) | 400VAC / 690VAC | 400A - 6300A | 3 / 4 Poles | Intelligent Microprocessor Controller |
| ARXM3 Series (MCCB) | 400V / 690V | 63A - 800A | 3 / 4 Poles | Thermal-Magnetic (Adjustable/Fixed) |
| ARM3E Series (MCCB) | 400V / 690V | 125A - 630A | 3 / 4 Poles | Electronic with Built-in LSIG Protection |
| ARM6DC Series (DC MCCB) | 700VDC / 1000VDC / 1500VDC | 100A - 250A | 2 / 4 Poles | Thermal-Magnetic Protection for Solar PV |
Customization options tailored for international brands, distributors, and large-scale industrial projects.
We utilize a structured process to transition projects from concept to final product delivery:
Key information for electrical engineers and procurement managers.
Thermal-magnetic trip units use a bimetallic strip to protect against overloads (via heat deflection) and an electromagnetic mechanism to protect against short circuits. They are simple, reliable, and cost-effective. Electronic trip units use a microprocessor to monitor current via current transformers (CTs) and provide adjustable LSIG settings: Long time delay (overload), Short time delay (short-circuit selective protection), Instantaneous (short-circuit protection), and Ground fault protection. This allows for precise calibration and coordination in complex distribution systems.
At altitudes above 2000 meters, the thinner air reduces convective cooling and lowers dielectric strength. This requires derating the circuit breaker's rated operational current (Ie) and insulation voltage. Designers should use derating tables to ensure safe, stable operations in high-altitude environments.
Yes, we manufacture dedicated solar PV circuit breakers. This includes models like the ARM6DC series, designed to handle operational voltages up to 1000VDC or 1500VDC. These units are built to manage the unique characteristics of DC arcs in solar energy systems.
Our circuit breakers are manufactured in ISO9001 certified facilities and comply with international standards such as IEC/EN 60947-2 (for industrial circuit breakers) and IEC/EN 60947-4-1. We support customers in obtaining regional certifications, including CE, CB, CCC, and RoHS, based on specific market needs.
We manage quality control using integrated PLM, BI, ERP, and MES software. Our specialized laboratory features over 150 test instruments operated by 20+ quality assurance inspectors. We conduct mechanical endurance tests, short-circuit interruption testing, and thermal calibration checks on every production batch.
