Direct factory supply with robust certifications. Explore our premier selection of low voltage electrical protection systems and engineered components.
The modern electrical grid is undergoing a paradigm shift driven by decarbonization, electrification of transport, and the explosion of digital infrastructure such as hyperscale data centers. This has fundamentally changed the operational demands placed on low-voltage switchgear, particularly Molded Case Circuit Breakers (MCCBs) and Air Circuit Breakers (ACBs).
As global industries scale up, the requirement for high-breaking capacities (such as 100kA to 200ka systems) has transitioned from a specialized request to a standard specification. Circuit breakers must now operate safely in higher ambient temperatures, withstand harmonic distortions from variable frequency drives, and manage the high-transient currents of solar photovoltaic arrays.
Founded in 2015, Acereare Electric operates two wholly-owned subsidiaries, "RuiRui Electric" and "KeRui Electric". Specializing in Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and key internal components, we represent a legacy of technical excellence.
With over 20 years of craftsmanship inherited by two generations, Ruiru Electric was officially registered in 2015, laying the groundwork for our contemporary growth strategy. Today, Acereare ranks as a premier ODM and OEM manufacturer in China, backed by deep technical reserves, integrated supply chain capabilities, and strict quality control frameworks.
We have forged strategic cooperative partnerships with nearly 100 high-end domestic and international clients, engineering customized solutions for energy infrastructure, marine docks, high-altitude installations, and high-precision automation systems.
We deliver value through advanced R&D, vertical supply chain integration, and rigorous testing frameworks.
We provide a true one-stop service encompassing six unique processing techniques. Armed with high-precision production machinery and testing apparatus, we operate more than 10 manual and automated assembly lines designed for speed and reliability.
Our division features over 50 R&D engineers expert in 3D structural analysis, parts design, and mold construction. Launching more than 50 R&D initiatives annually, we transition custom concepts into certified products rapidly.
Operating two dedicated manufacturing facilities allows us to segment component production and final assembly. With systems integrated through ERP and U8 management software, we align production lines with real-time customer schedules.
Quality is assured via a multi-phase inspection process utilizing over 150 testing apparatus in our in-house test lab. Managed through PLM, BI, ERP, and MES software, 20+ QC inspectors verify compliance at every production stage.
How Acereare Combines Traditional Craftsmanship with Industrial Automation
Our manufacturing facility integrates modern automated stamping lines with high-performance silver plating processes. This is critical for parts like our 250A Moving Contacts with Silvering, which prevent micro-arcing and limit resistance variations over thousands of operating cycles.
By keeping key component processing—such as sheet metal stamping, busbar molding, and plastic injection—in-house, we control mechanical tolerances to within microns. This vertical control optimizes circuit breaker trip curves and guarantees consistent performance under overload conditions.
Our products undergo comprehensive certification, complying with standard electrical regulations globally.
We design and manufacture low-voltage switchgear to meet diverse current, voltage, and protection demands.
Specifications: AC 50Hz, Rated voltage 690V and below, Rated current 400A to 6300A.
Protection & Comms: Integrated intelligent control unit providing high-accuracy selective protection. Equipped with an open communication protocol supporting "remote sensing, remote adjustment, remote control, and remote signaling" (the "four remotes") to integrate with automation networks.
Designed for basic distribution protection and earth leakage safety. Built with impact-resistant engineering plastics and arc extinguishing chambers to safely handle short-circuit faults.
Thermal-magnetic adjustable MCCB spanning 63A to 400A. A versatile unit offering adjustable thermal trip settings to accommodate load profile changes without replacing the breaker.
Features an adjustable electronic trip unit (LSIG) providing precision current monitoring and configurable trip curves. Ideal for critical motor protection and automated process environments.
Engineered for high breaking capacity up to 200kA. Suitable for mains distribution points in heavily loaded industrial structures and grids.
Features integrated LCD displays, remote diagnostics, and energy metering. Supports real-time current, voltage, and power tracking to enable smart grid analytics.
Acereare products are engineered to operate reliably across demanding environmental conditions.
For operations extending down to -40℃, we use low-temperature resistant materials and low-viscosity oils. Components feature thickened plating finishes, backed by comprehensive low-temperature performance reports.
Designed for port installations and marine environments. We conduct 72-hour salt spray testing on finished units and 48-hour testing on components. These assemblies withstand high humidity and saline atmospheres to prevent mechanical binding.
For installations exceeding 2000 meters, thin air reduces thermal dissipation and dielectric strength. We configure correction coefficients based on altitude derating data to ensure safe dielectric parameters.
Our compact MCCBs protect household and commercial electrical appliances against overload and short-circuit damage, offering easy installation, small footprints, and long service life.
Engineered for high-heat environments. Utilizing thermal barrier layers on control elements along with treated copper and iron components, we test performance within 55℃ environmental chambers to verify thermal stability.
Units integrating communication, metering, protection, and edge computing. These breakers report electrical parameters to upstream control systems, facilitating power monitoring and remote load shedding.
We support global brands with custom structural designs, fast prototyping, and flexible production schedules.
We print or laser-etch custom brand logos and provide customized packaging (outer/inner cartons) and product catalogs. These services help electrical distributors build brand equity backed by stable, verified hardware.
