Heavy-duty switchgear components built to precise mechanical tolerances, supporting Mexico City's industrial nearshoring energy distribution demands.
Founded on over 20 years of generational manufacturing expertise, Acereare Group operates alongside its wholly-owned subsidiaries, RuiRui Electric and KeRui Electric. Our manufacturing plants stand among China’s top premier OEM/ODM centers for low-voltage power distribution products. We specialize in high-precision metal stamping, progressive stamping dies, and Molded Case Circuit Breakers (MCCB) designed to protect industrial machinery and electrical grids globally.
By leveraging advanced machinery, CAD/3D structural design software, and a strict quality assurance workflow managed by integrated PLM, BI, ERP, and MES software, we support tier-1 electrical assemblers and switchgear builders in Mexico City and neighboring industrial zones with reliable high-volume supply chains.
Mexico City, along with the broader Valle de México and the industrial corridors of Querétaro, Estado de México, and Puebla, is experiencing a major expansion in manufacturing. Driven by USMCA nearshoring trends, multinational OEMs are setting up advanced production lines, data centers, and clean energy projects. This growth demands robust, reliable electrical infrastructure to handle demanding power loads.
Our precision metal stamping parts, contact systems, and circuit breakers are specifically designed to meet these regional challenges:
High-vibration resistant connection terminals and busbars designed for automated manufacturing plants and EV battery management systems.
Low-loss copper busbars and high-capacity MCCBs configured to support uninterruptible power supplies (UPS) and large-scale cooling loops.
Specialized Solar MCCBs designed for high-voltage DC installations up to 1000V/1500V, ensuring reliable overcurrent protection.
Because Mexico City is located at a high altitude of 2,240 meters above sea level, electrical assemblies must account for thinner air, which reduces heat dissipation and dielectric insulation. We work closely with Mexican engineering departments to adjust breaker configurations based on high-altitude performance tables, ensuring safe and reliable operation in these environments.
Engineered components designed for solar power arrays and mechanical safety systems in heavy commercial grids.
We rely on advanced stamping and manufacturing systems to deliver reliable quality, high volume, and low defect rates. Our facilities utilize progressive stamping lines, multi-slide forming machines, and automated assembly stations. This setup minimizes dimensional variance and ensures clean contact surfaces for critical switchgear assemblies.
Tested and certified component configurations to resist temperature swings, marine corrosion, high altitudes, and extreme operating stresses.
Utilizes specialized low-temperature resistant lubrication and structural steel components, verified through certified lab testing down to -40°C.
Stamping parts pass a 72-hour salt spray test for completed breakers and a 48-hour test for component coatings, protecting switchgear against humid marine climates.
Optimized insulation clearances and copper gauge profiles configured to handle high-altitude operating conditions, such as those in Mexico City.
Compact MCCBs and components optimized for high-density electrical cabinets, commercial buildings, and domestic distribution boards.
Thermal stability is verified through continuous operation in a 55°C environment. We use custom coatings to protect current-carrying parts from heat damage.
Internal copper structures configured to house smart monitoring, communication, and edge computing sensors, supporting modern smart grids.
How we manage tool engineering and logistics for distributors and OEMs in Mexico City.
We review 2D/3D part drawings and specify materials, plating thicknesses, and target tolerances.
We construct high-speed progressive dies in-house and submit initial stamped samples for physical testing.
High-speed stamping presses run automatically, with quality monitored via MES tracking systems.
Parts are packed to prevent moisture during shipping and dispatched directly to regional facilities in Mexico.

We maintain strict adherence to international electrical safety regulations to ensure compliance in demanding global markets.
Common questions regarding custom tooling, mechanical adjustments, and international shipping to Mexico.
At altitudes above 2000 meters, such as Mexico City's 2,240m elevation, the thinner air reduces convective heat dissipation and decreases dielectric insulation strength. For custom components, we increase structural clearances, expand copper terminal surface areas, and apply specialized plating coatings. The circuit breakers are adjusted using high-altitude derating tables to ensure safe, stable operation.
We source certified, high-purity C1100 copper (99.9% purity) for optimal electrical conductivity. For high-wear internal mechanisms, such as moving contacts and terminals, we utilize brass, beryllium copper, or spring steels, combined with silver-alloy (Ag) contacts to minimize resistance and heat build-up under load.
Our in-house design and engineering tooling department can construct a custom progressive stamping mold within 25 to 35 days from blueprint approval. Initial prototype samples are delivered within 5 days of tooling completion for structural and electrical testing.
Yes, our products conform to key international safety guidelines, including IEC 60947-2, CE, and RoHS standards. We also support OEM partners during the UL 489 or NOM (Normas Oficiales Mexicanas) certification processes by providing complete physical properties documentation, material certificates, and test laboratory reports.
