Specializing in MCCB, ACB & related components. Two wholly-owned subsidiaries. Over 20 years of craftsmanship. Trusted by 100+ global partners.
Acereare Electric was founded in 2015, operating two wholly-owned subsidiaries — RuiRui Electric and KeRui Electric. We are a professional original manufacturer integrating R&D, production and sales, specializing in Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB) and related components.
With over 20 years of craftsmanship inherited by two generations, Ruiru Electric was officially registered and established in 2015, marking the start of the current proprietor's entrepreneurial journey. Boasting solid technical accumulation and a mature production system, our factory ranks among the top well-known ODM manufacturers in China in terms of comprehensive experience and professional capabilities.
We have established strategic cooperation relationships with nearly 100 high-end customers at home and abroad, delivering world-class electrical protection solutions across diverse industries and environments.
Decade-long expertise backed by measurable achievements in manufacturing, R&D, quality assurance, and global delivery.
Adhering to the core value of win-win cooperation, we have built a solid reputation among our customers for outstanding service, first-class products and unbeatable prices.
One-Stop Service. Six kinds of Processing Technic. High precision production equipment and testing instruments. More than 10 manual and automated production lines.
More than 50 R&D engineers with over 5 years of work experience. Familiar with 3D software design of parts, molds, and finished machine drawings. 50+ research and development projects per year.
Owning two factories to expand the production of components and complete machines. Integrate management by linking various processes and departments through ERP and U8 software.
A rigorous and multi-step quality inspection process. Owning its own laboratory to test the quality of parts. More than 150 sets of testing instruments and over 20 inspectors. Control quality through software such as PLM/BI/ERP/MES.
We are dedicated to designing and manufacturing a wide array of circuit breakers with premium quality and unmatched reliability.
The ARM1 Series MCCB offers reliable overcurrent and short-circuit protection for industrial and commercial power distribution systems. Engineered with precision components for long-lasting performance.
The ARM1L Series is a compact-design molded case circuit breaker optimized for space-constrained environments. Ideal for residential and light commercial installations requiring reliable circuit protection.
The ARXM3 Series features advanced trip mechanisms and enhanced breaking capacity, designed for demanding industrial power distribution environments with high fault current requirements.
The ARM3E Series integrates earth leakage protection with standard MCCB functions, providing comprehensive safety for personnel and equipment in moisture-prone environments.
The ARM5 Series large-frame MCCB is engineered for high-current applications in heavy industrial environments, offering superior breaking capacity and thermal-magnetic protection.
The ARM6 Series delivers ultra-high breaking capacity and exceptional reliability for critical power infrastructure, including data centers, substations, and large-scale industrial facilities.
ARW1 series intelligent type ACB is applicable to the AC 50HZ distribution network with rated voltage of 690V and below, and rated current from 400A to 6300A. The ACB has intelligent protection function and high precision selective protection to improve power supply reliability. At the same time, it is equipped with an open communication interface, which can carry out the four remote functions of "remote sensing", "remote adjustment", "remote control" and "remote signaling" to meet the requirements of the control center and the automation system.
The ARW3 Series draw-out ACB features advanced intelligent trip units and modular accessories, enabling rapid maintenance and flexible system configuration for large power distribution networks.
Acereare supplies a comprehensive range of MCCB spare parts and components, including trip mechanisms, contact assemblies, arc chutes, and terminal covers — all manufactured to OEM specifications for direct compatibility.
We provide specific Circuit Breaker solutions to match your industry's requirements for accurate functionality and exceptional performance.
We use low-temperature resistant materials, apply low-temperature oil, parts are usually treated with thickened coating, and we have a low temperature test report of -40℃.
We can conduct salt spray tests, usually making 72 hours for the complete machine and 48 hours for the semi-complete machine. MCCB can withstand the effects of humid air at the sea and salt spray, ensuring the stable operation of power equipment. They are widely used in dock power systems to protect key equipment such as motors and transformers.
If the altitude exceeds 2000m of the applicable working environment, the electrical performance of the circuit breaker should be adjusted coefficient by a high-altitude derating table.
MCCB are widely used in household appliances to protect them from damage caused by circuit overload or short circuit faults. They have the advantages of high flexibility and improved operational reliability.
We use high temperature resistant materials. The surface of the controller should be coated with a thermal insulation layer, and the copper and iron parts should be moisture-proof, salt spray resistant, and corrosion-resistant. We explore the technical data of MCCB's high temperature resistance by conducting experiments in our constant temperature room of 55℃.
MCCB provides comprehensive protection functions, including communication, metering, protection, control and edge computing. It supports a variety of communication technologies, providing a solid foundation for the realization of smart grid and measurement applications.
