Advanced circuit breakers engineered to meet EU low-voltage standards and optimized for local distribution requirements in the Berlin-Brandenburg metroplex.
Aligning low-voltage electrical protection with Germany's Energiewende goals and metropolitan grid enhancements.
As the capital of Germany drives towards zero-carbon emissions under the Berliner Energiewendegesetz, the electrical layout of both industrial systems and urban commercial environments is shifting. Traditional localized grids are giving way to active networks featuring massive bi-directional loads: EV charging points, building-integrated photovoltaics (BIPV), and battery storage systems (BESS). This complex integration demands ultra-precise circuit protection. Transient harmonics, back-feeding currents, and extreme short-circuit fault levels mean that standard switches are no longer sufficient. Moulded Case Circuit Breakers (MCCBs) like the ARXM3 series serve as a critical defense line, preventing equipment damage and assuring continuous power supply.
“In contemporary urban networks like Berlin-Adlershof or Siemensstadt 2.0, an electrical outage does not merely represent a minor inconvenience—it incurs massive downtime costs and compromises smart municipal systems. The demand for highly selective, smart-communicative MCCBs with high breaking capacities at 400V and 690V is rising exponentially.”
In the surrounding Brandenburg manufacturing clusters and Berlin's urban technology parks, commercial machinery operates under rigid safety directives. Electrical safety compliance with DIN VDE standards is non-negotiable. Industrial facilities require thermal-magnetic circuit breakers that perform reliably under varied ambient conditions, including elevated temperatures inside compact control panels or low-temperature environments in outdoor utility enclosures. The ARXM3 Series addresses these needs by combining high electrical durability with adaptable configuration options like plug-in bases, undervoltage releases, and auxiliary contacts for real-time SCADA connectivity.
Our Legacy in Intelligent Circuit Protection Manufacturing
Founded in 2015, Acereare Electric features two wholly-owned subsidiaries: "RuiRui Electric" and "KeRui Electric". As a professional original manufacturer integrating R&D, production, and sales, we specialize in high-performance molded case circuit breakers (MCCB), air circuit breakers (ACB), and related precision components.
With over 20 years of craftsmanship inherited by two generations, we have established strategic partnerships with nearly 100 high-end customers globally. Boasting a solid technical foundation and a mature production ecosystem, our factory ranks among China’s top OEM/ODM manufacturers for comprehensive low-voltage electrical systems.
Delivering high-end customization, reliable supply chains, and stringent quality assurance to global standards.
ARXM3 Series MCCB customization capabilities for demanding global environments.
Utilizing high-impact low-temperature-resistant polymers, specialized internal lubricants, and thickened protective plating on functional copper elements. Validated with testing down to -40°C, ensuring reliable operations in cold storage facilities and outdoor enclosures in northern Europe.
Our components undergo 72-hour salt spray testing for finished assemblies and 48-hour testing for key sub-assemblies. This protects equipment from humid marine air, preventing premature degradation of contacts. Well-suited for harbor infrastructure, docks, and coastal wind farms.
For operations above 2000m, standard electrical clearances and dielectric breakdown levels change due to thin air. We provide precise high-altitude derating tables and adjusted thermal parameters to guarantee continuous insulation safety and rated operational currents without premature tripping.
Integrating compact MCCBs in modern commercial panels and HVAC distribution systems. Offering high flexibility, robust housing, easy DIN rail compatibility, and simplified installation parameters, they enhance operation uptime for malls, residential towers, and utility boards.
Using premium thermosetting compounds, heat-resistant barriers, and anti-corrosive treatments. Tested inside constant-temperature environment chambers at +55°C to determine derating indices, making these switches suitable for desert PV combiner panels and compact factory control boxes.
Advanced MCCB units support metering, edge computing, control, and remote Modbus/RS485 communication. They enable real-time tracking of current, voltage, power factor, and harmonics. This data feeds into smart factory SCADA systems for predictive maintenance and energy audit initiatives.
Supporting distributors, grid operators, and electrical panel builders with tailored contract manufacturing services.
We provide authorized trademark laser marking and packaging options to help you scale your local presence. This allows European engineering firms and distributors to offer robust circuit breakers under their own label without maintaining costly production facilities. Standard catalog customization and low-MOQ test orders are available to speed up market entry.
From mold adjustments to dynamic simulation of thermal-magnetic trips, our engineering division offers design calculations, compliance reviews, and custom termination plates to fit specific enclosure shapes. Our R&D team works closely with your engineering group to verify dimensions, current paths, and breaking performance before batch production begins.
A deep engineering dive into the design mechanics, interruption capability, and protection curves of the ARXM3 series.
The core of the ARXM3 series' high performance lies in its arc-extinguishing chamber. Under short-circuit conditions, the contact arm moves quickly due to electrodynamic forces, drawing an arc into the splitter plates. The plates divide, cool, and extinguish the arc within milliseconds. A zero-arcing design prevents ionized gases from venting outside the breaker, reducing safety clearance requirements inside electrical switchboards and protecting nearby copper busbars from carbon deposit build-up.
Selectivity prevents cascading blackouts by ensuring only the circuit breaker closest to the fault trips. The ARXM3 Series features adjustable thermal-magnetic trip characteristics, allowing electrical engineers to configure precise time-current selectivity profiles. By coordinating upstream Air Circuit Breakers (such as the ARW1-3200 series) with downstream ARXM3 units, installations achieve total discrimination up to high fault currents. This layout ensures critical loads remain powered while isolating localized electrical faults.
The modular layout of the ARXM3 allows quick field installation of accessories without specialized tools. Auxiliary contacts, shunt trips, and undervoltage releases share standardized dimensions, inserting directly into internal slots beneath the front cover. Safe insulation barriers separate these control circuits from the main power poles, preventing voltage creepage and ensuring operator safety during commissioning and maintenance.

How Acereare is adapting circuit breakers for the next wave of industrial automation.
Traditional mechanical contacts are subject to wearing arcs during high-current interruptions. Acereare's R&D division is researching hybrid solid-state technology. By integrating power electronics with fast mechanical contacts, current is diverted into bypass paths, minimizing arcing. This system aims to support millions of operations without contact erosion, addressing the requirements of high-frequency switching applications like solar farms and automated battery cycling plants.
We are upgrading our internal communication architectures to feature Modbus-RTU, Profibus-DP, and native Ethernet connectivity options directly within MCCB accessory cavities. These components provide predictive health analysis by measuring real-time contact temperature, wear rates, and thermal trip history. By integrating directly with cloud energy management platforms, operators can address wear issues before they lead to unexpected system failure.
We are committed to reducing the environmental impact of our components. Our upcoming products use halogen-free, recyclable thermosetting compounds that meet strict EU RoHS and WEEE directives. Additionally, we are optimizing our automated assembly processes to cut energy consumption and minimize scrap metal waste, supporting clean manufacturing practices.
