Delivering Precision Electrical Contacts, Copper Busbars, and Custom Moldings Engineeed for Kazakhstan's Mining, Petrochemical, and Renewable Energy Networks.
Precision-crafted copper and structural stamping components engineered to meet the stringent electrical grid requirements of Kazakhstan's extreme temperature operations.
Kazakhstan has established itself as the economic engine of Central Asia. The massive industrial projects in the Karaganda and Pavlodar regions, alongside oil and gas exploration in Tengiz and Kashagan, place enormous stress on local electrical infrastructure. With the modernization of the national grid under the auspices of KEGOC (Kazakhstan Electricity Grid Operating Company), there is a rapidly escalating demand for high-performance low-voltage switchgear. In parallel, Kazakhstan’s national strategy for green energy expansion has sparked massive construction of wind farms in the Ereymentau region and solar parks in Zhambyl, requiring dedicated high-voltage DC equipment such as 1500VDC Photovoltaic Molded Case Circuit Breakers (MCCBs).
To safeguard critical mining operations, smelting plants, and regional distribution grids, switchgear manufacturers must source internal components with absolute reliability. MCCB metal stamping moldings, including terminal busbars, stationary contacts, and moving contact assemblies, form the physical backbone of circuit breakers. A minor structural deviation or low-grade copper base can trigger catastrophic arc flashovers under short-circuit stresses (often reaching up to 100kA breaking currents in heavy industrial grids). Our custom stamping lines deliver the precision and mechanical tolerances needed to guarantee long-term operational integrity under these harsh regional demands.
Providing components designed to resist constant vibrations, high ambient temperatures, and dust in smelting facilities across Zhezkazgan and Pavlodar.
Engineering specialized copper components and stamping busbars that handle continuous DC loads in utility-scale solar arrays without overheating.
Fully certified raw materials conforming to the Eurasian Economic Union (EAEU) standards, guaranteeing smooth custom clearance and integration.
Founded in 2015, Acereare Electric operates through its two wholly-owned manufacturing subsidiaries: RuiRui Electric and KeRui Electric. We are a professional, integration-driven original manufacturer specializing in the research, design, production, and worldwide distribution of Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and high-precision metal stamping components.
Inheriting over 20 years of craftsmanship across two generations, Acereare Group stands at the forefront of China's electrical manufacturing sector. With deep technical accumulation and advanced, automated production facilities, we deliver world-class ODM/OEM services. Our strategic partnerships extend to over 100 high-end electrical engineering clients globally, supplying critical safety components that power heavy-duty industrial systems.
The structural reliability of an MCCB lies in its mechanical components. Arc extinguishing chambers, load-side and line-side terminals, sliding assemblies, and magnetizer plates require precise manufacturing tolerances. Even a microscopic variance can increase contact resistance, generating localized heat and causing the breaker to trip prematurely or fail under short-circuit faults.
Our production facilities utilize advanced progressive stamping dies running on high-speed press lines. This machinery processes raw copper and alloy sheets with tolerances held down to ±0.005mm. To counter the high thermal stresses during contact opening, we use high-conductivity, oxygen-free copper (Grade T2) combined with premium silver-refractory contact tips (AgW, AgWC). Our progressive die setups guarantee physical alignment across production batches, allowing seamlessly repeatable operation of the circuit breakers.
Multi-stage progressive tooling performs blanking, forming, bending, and punching on a single line, maximizing structural strength and accuracy.
We integrate state-of-the-art automated brazing lines to fuse silver contact tips with copper backings, preventing contact separation under thermal shock.
Automated electroplating lines apply precise nickel, tin, or silver plating to prevent oxidation on the copper surfaces in humid and corrosive environments.
Kazakhstan experiences one of the most extreme continental climates in the world, with temperatures fluctuating from -40°C in winter to over +50°C in summer. These swings cause significant thermal expansion and contraction in metal components. Electrical systems must be engineered to withstand these variations to prevent premature failure. Our products are specifically tested and certified to handle these extreme environmental challenges.
We utilize cold-hardened low-alloy structural steels and specialized low-temperature lubricants. Our finished MCCBs undergo verification testing down to -40°C to guarantee smooth spring mechanism releases in northern Kazakhstan.
For marine port installations in Aktau and coastal chemical processing centers, we apply thickened electroplated nickel/tin barriers. Components undergo a 72-hour salt spray test to ensure resistance to saline corrosion.
For mining installations in the Tien Shan range, thin mountain air reduces insulation properties. We design stamping clearances and creepage distances to match altitude-derated voltage curves.
We supply core internal shunt resistors and high-precision current transformer cores. These components enable real-time energy metering, grid diagnostic reporting, and edge computing.
For solar projects in Zhambyl and Shymkent, our components use high-temp polymers and thermal-insulating coatings. We run constant-temperature tests at 55°C to ensure reliable trip calibration under high ambient heat.
Residential and commercial distribution boxes rely on our miniature and molded case components. Our stampings maintain consistent contact pressure to protect household electronics from overloads.

Providing system protection for heavy industrial distribution networks, mining operations, and utility power facilities throughout Kazakhstan.
To compete effectively, switchgear manufacturers require custom-tailored solutions rather than standard off-the-shelf components. Acereare Group provides end-to-end OEM and ODM support, managing the production process from initial design to final packaging.
Build brand value with customized logos and product markings. We utilize high-quality raw materials to ensure product longevity, while quick-turn sample fabrication speeds up product qualification and market entry.
We provide specialized engineering and testing services for manufacturers worldwide, including custom mold design and international test documentation.
From specialized branding to custom packaging designs, we act as an overseas manufacturing partner to support scalable growth.
Modern power grids are evolving to handle bidirectional power flows, distributed energy systems, and digital monitoring. In response, molded case circuit breakers are transitioning from basic mechanical safety devices to smart, data-enabled control nodes. Our technical roadmap focuses on developing components that support this transition.
Key focus areas include micro-alloy plating techniques that reduce contact wear under high switching cycles, and smart sensor integration directly into copper terminal stampings. By embedding temperature and current sensors into the metal stampings, next-generation MCCBs can detect heat anomalies before contact damage or fires occur. These smart-grid compatible switchgear components are designed to support Kazakhstan's infrastructure modernization initiatives.
