Explore our high-performance electrical circuit protection units. We deliver reliable, certified equipment directly from China's leading manufacturing hubs to global industrial installations.
Founded in 2015, Acereare Electric has rapidly established itself as a premier original manufacturer integrating R&D, production, and sales. Operating two wholly-owned subsidiaries—"RuiRui Electric" and "KeRui Electric"—our brand is built on a rich heritage. With over 20 years of craftsmanship inherited by two generations, our transition in 2015 marked the launch of our current industrial capabilities.
Boasting solid technical accumulation and a mature production system, our factories rank among the top well-known ODM manufacturers in China. We specialize in Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and high-precision electrical components.
As the nervous system of modern power grids, Air Circuit Breakers play an indispensable role in safeguarding heavy industrial equipment, utility distribution networks, and critical commercial complexes.
The rapid expansion of energy-intensive industries, including automated automotive plants, semiconductor cleanrooms, and chemical processing facilities, has elevated the demand for reliable overcurrent protection. Modern facilities operate 24/7, making sudden power disruptions incredibly costly. ACBs act as the ultimate failsafe, mitigating catastrophic thermal events.
Utility-scale solar farms and wind turbines frequently experience variable loads. Standard circuit breakers often fail under these dynamic operational patterns. Smart ACBs engineered with micro-processor trip units are designed to manage 800VAC levels common in photovoltaic arrays, ensuring seamless grid synchronization and localized fault isolation.
The global push for net-zero carbon footprints requires transitioning fossil-fuel processes to electric power. Infrastructure like EV hyper-charging hubs and data centers demand higher continuous current protection (from 2000A up to 6300A). High-capacity ACBs like our ARW1 series provide the precise electrical protection required to support this energy transition.
| Circuit Breaker Type | Typical Voltage Rating | Standard Current Range | Breaking Capacity (Icu) | Primary Industrial Applications |
|---|---|---|---|---|
| Air Circuit Breaker (ACB) | 400VAC to 690VAC | 630A to 6300A | Up to 120kA | Main power distribution, generators, large factories, data centers |
| Molded Case Circuit Breaker (MCCB) | Up to 1000VAC / DC | 16A to 1600A | Up to 85kA | Motor protection, sub-distribution boards, solar PV combiners |
| Miniature Circuit Breaker (MCB) | 230V / 400VAC | 0.5A to 125A | Up to 15kA | Residential distribution, lighting control, control circuits |
The future of low-voltage electrical protection lies in digitalization, edge intelligence, and material innovations.
Acereare is currently investing in eco-friendly arc extinguishing materials, minimizing SF6 or hazardous plating elements. We focus on developing compact chassis drawers that withstand high seismic forces, catering to critical infrastructure in regions prone to earthquakes or industrial vibrations.
By utilizing simulated 3D modeling and automated thermal dynamic testing, our R&D center refines contact geometries to lower resistance and minimize heat generation under full-load operation.
We adhere to the core value of win-win cooperation, building a solid reputation through outstanding service, premium manufacturing, and globally competitive pricing models.
One-Stop Service utilizing six distinct manufacturing techniques. Armed with high-precision production machinery and calibration instruments, we run more than 10 manual and automated production lines to secure volume output.
Our team consists of 50+ R&D engineers, each possessing over 5 years of domain experience. We are fully proficient in 3D CAD modeling of components, molds, and finished assemblies, delivering 50+ custom research projects annually.
Operating two specialized factories to optimize component stamping and complete breaker assembly. We integrate logistics and departmental tracking using professional ERP and U8 software management suites.
A rigorous, multi-step quality control protocol. Our in-house testing facility houses over 150 dedicated testing instruments managed by 20+ QC inspectors. Operations are monitored using PLM, BI, ERP, and MES software.
The ARW1 series intelligent type ACB is designed for AC 50Hz/60Hz distribution networks with a rated voltage of 690V and below, spanning rated currents from 400A to 6300A.
Equipped with smart microprocessor trip units, this circuit breaker series offers high-precision selective protection to prevent wide-scale power interruptions. It includes an open communication interface to support four remote monitoring functions:
Provides seamless integration with automated industrial control centers and regional grid automation systems.
We design and build customized electrical protection units capable of performing reliably under extreme environmental stress.
For sub-zero climates, we utilize low-temperature resistant metals and structural polymers, combined with specialized low-viscosity mechanical oils. Our products are fully certified with low-temperature test reports down to -40°C.
Critical for marine operations, docks, and coastal power stations. We conduct 72-hour salt spray testing on complete machines and 48-hour testing on assemblies. This prevents corrosion on critical components, ensuring reliable operation under high humidity.
At elevations exceeding 2000m, lower atmospheric pressure reduces the air's insulation properties and heat dissipation capability. Our engineering team applies strict altitude derating coefficients to modify clearances and select appropriate insulating media.
Our circuit breakers provide reliable safety protection in commercial buildings and large residential installations. They protect wiring and connected appliances against high-current overloads and short circuits, minimizing downtime.
To prevent overheating in environments up to 55°C, we apply thermal insulation barriers to controllers and treat copper and iron components to prevent oxidation, verified through testing in our environmental simulation chambers.
Provides critical telemetry, metering, and edge computing capability. Supporting direct communication protocols, our units integrate cleanly into regional distribution management systems and IoT utility grids.
We manage the complete workflow from product specification design to delivery, serving as your reliable overseas manufacturing partner.
Our systems are fully compliant with ISO 9001, and our products carry relevant international certifications to ease import processes.

While both protect electrical systems from overloads and short circuits, they serve different layers of the grid. Air Circuit Breakers (ACBs) are used at the main incoming power points, managing high current loads (up to 6300A) and featuring high short-time withstand currents (Icw). This allows down-stream breakers to trip first without tripping the main breaker unnecessarily.
In contrast, Molded Case Circuit Breakers (MCCBs) protect downstream circuits (up to 1600A) and are typically installed in sub-distribution boards to isolate smaller motors, heaters, or feeder branches.
At altitudes above 2,000 meters (6,500 feet), the thinning air reduces cooling efficiency and lowers the dielectric strength of the air gap. Consequently, circuit breakers require derating coefficients.
This means a breaker rated for 2000A at sea level may need to be derated to 1800A at higher altitudes to prevent excessive heat buildup. The insulation resistance clearances must also be checked to prevent electrical arcing across air gaps.
LSIG represents the four stages of modern digital trip unit protection:
In heavy manufacturing, LSIG protection helps isolate faults to a single production line, preventing widespread factory power outages.
