High-precision stampings, contact configurations, and thermal breakers optimized for Thailand's demanding electrical infrastructure.
Bangkok, together with its surrounding industrial clusters in Samut Prakan, Pathum Thani, and the Eastern Economic Corridor (EEC) zones of Chonburi and Rayong, represents the manufacturing engine of Thailand. Known as the "Detroit of the East," the country’s high concentration of automotive assembly lines and electronic parts factories requires massive quantities of low-voltage switchgear components, molded case circuit breakers (MCCBs), and precision metal stamping elements.
As Bangkok spearheads the transition toward smart city infrastructure and the deployment of massive solar photovoltaic setups across industrial rooftops, the requirement for highly durable MCCB parts has reached unprecedented heights. Tropical climates bring specific environmental challenges: high humidity levels, persistent maritime salt sprays near the Gulf of Thailand, and high ambient temperatures exceeding 40°C. General-purpose stamping parts suffer accelerated fatigue under these conditions. Our customized metal stampings feature high-purity C1100 copper substrates and specialized silver-plating coatings designed to suppress thermal runaway, guarantee low contact resistance, and ensure uninterrupted current paths.
Furthermore, with the Thai Board of Investment (BOI) offering tax breaks and investment incentives to projects under the "Thailand 4.0" framework, companies in Bangkok are actively upgrading their manufacturing plants. Integrating energy management platforms and IoT-connected switchgears requires precision circuit breakers with optimized stamping components to house smart measurement coils and electronic trip devices safely.
The global paradigm shift toward high-voltage solar energy systems and rapid EV charging networks mandates a redesign of low-voltage circuit protection technologies.
Globally, low-voltage distribution networks are moving from traditional 400V/690V thresholds to high-performance PV solar circuits operating at 800VAC, 1000VAC, and up to 1500VDC. Breaking arcs in these high-voltage regimes generates extreme thermal and mechanical stresses. The mechanical contacts and stamped terminals within MCCBs must withstand severe arc erosion and avoid contact welding. Our manufacturing strategy targets these global needs by integrating heavy-duty silvering and specialized copper alloy substrates.
To maintain electrical reliability over 10,000+ mechanical switching cycles, international OEMs demand tight dimensional tolerances, typically within ±0.01 mm, for all progressive stamping parts. Advanced metallurgical selection, including high-conductivity oxygen-free copper (C1020/C1100), ensures optimal heat dissipation. This material choice reduces contact degradation, minimizes watt-loss values, and guarantees compliance with IEC 60947-2 standards.
Established in 2015, Acereare Electric operates through its two fully owned subsidiaries: "RuiRui Electric" and "KeRui Electric." We combine over 20 years of craftsmanship, spanning two generations, with a modern industrial footprint. Our factories serve as premier ODM and OEM partners for global electrical brands, specializing in molded case circuit breakers (MCCB), air circuit breakers (ACB), and precision metal stamping accessories.
With an integrated production chain, we handle tool design, high-speed progressive metal stamping, contact surface plating, electronic welding, and final device calibration in-house. This direct oversight enables us to maintain tight quality standards and adapt configurations to the specific industrial needs of Bangkok's power infrastructure projects.

Strip steel and copper coils feed into high-tonnage progressive presses. Multiple operations—piercing, blanking, forming, and coining—occur in a single automated run to maintain tight tolerances.
Stamped copper parts are silver-plated or nickel-plated to prevent oxidation, reduce contact resistance, and ensure clean current transfer under continuous thermal load.
Silver alloy contact tips (such as AgSnO2) are automatically brazed to the stamped arms. This process ensures high joint shear strength and consistent electrical performance.
We provide structured services for custom electrical components, supporting our customers from initial design through to final production delivery.

Common technical questions regarding copper stampings, contact metallurgy, and our logistics support for the Bangkok market.
C1100 copper (electrolytic tough pitch) offers an electrical conductivity rating exceeding 101% IACS, alongside excellent thermal conductivity. This combination minimizes power loss and prevents excessive heat build-up inside the molded case. Its good formability also makes it well-suited for high-speed progressive die stamping operations, allowing for precise shapes without micro-cracking.
Bangkok's high humidity and ambient temperatures, combined with coastal air in nearby industrial zones, can accelerate oxidation and galvanic corrosion. To address this, we apply a high-density nickel underplate followed by a specialized silver coating. This multi-layer finish resists oxidation and prevents copper migration, ensuring low contact resistance over the service life of the breaker.
Using precision-machined carbide tooling inserts and high-speed stamping presses, we maintain dimensional tolerances of ±0.01 mm for critical component features. Maintaining this precision is essential for ensuring reliable alignment, uniform contact pressure, and consistent trip characteristics across multi-pole configurations.
We manage sea freight shipments from our factories to Bangkok Port (Khlong Toei) or Laem Chabang.
