Designed for incoming feeder isolation, combining high fault breaking capability with advanced digital protection algorithms.
Australia's electrical grid is undergoing a historic structural shifts. Driven by extreme environmental conditions, mining expansions in Western Australia and Queensland, and a massive decentralization of renewable energy (utility-scale solar and wind projects), the demand for reliable, high-specification switchgear has never been more critical.
Historically, switchboard builders and EPC contractors in Brisbane, Sydney, Melbourne, and Perth relied on expensive European circuit breaker brands. Today, global supply chains, cost pressures, and the strict requirement for customized digital features have pushed engineers to seek direct manufacturing partnerships with Chinese state-of-the-art factories.
The ARM3E Series Electronic Adjustable MCCB answers this demand. By incorporating micro-processor controlled LSIG trip units, it provides precise selective coordination, minimizing the risk of arc flash incidents and localized faults cascading into complete system blackouts on remote sites.
Why electronic adjustable trip units outperform traditional thermal-magnetic breakers in complex commercial grids.
Long-Time (L) Overload Protection: Adjustable current setting (Ir = 0.4 to 1.0 x In) with customizable delay times to handle prolonged minor overcurrents. Short-Time (S) Short-Circuit Protection: Delay settings to allow coordination with downstream breakers during severe but brief faults.
Instantaneous (I) Trip: Fixed or adjustable thresholds reacting immediately (in milliseconds) to dangerous high-level short circuits. Ground-Fault (G) Protection: Vital for detecting phase-to-earth leakage currents, reducing fire risk and protecting personnel in wet or mining environments.
Unlike thermal-magnetic strips which degrade over time or are highly susceptible to ambient temperature shifts, the ARM3E microprocessor ensures digital calibration accuracy, reducing maintenance cycles and stabilizing trip curves.
In high-availability installations (like hospitals, data centers, and remote pump stations), a fault at an end-user device should only trip the breaker immediately upstream. If the main switchboard breaker trips instead, it cuts power to the entire facility. The ARM3E adjustable LSIG trip system allows engineers to configure precise cascading time and current delays, ensuring only the faulted branch goes dark.
Founded in 2015, Acereare Electric operates through its two fully owned specialized subsidiaries: RuiRui Electric and KeRui Electric. As one of China's premier original manufacturers (ODM) of molded case circuit breakers (MCCB), air circuit breakers (ACB), and structural circuit breaker components, we bring over two generations of engineering heritage.
By integrating product development, component stamping, injection molding, and computerized testing under one roof, we eliminate intermediate supply chain layers. This guarantees that our Australian partners receive reliable quality, fast sample turnarounds, and pricing that keeps switchboard designs competitive.
Our ARM3E units are built to withstand unique environmental and operating challenges typical of the Southern Hemisphere.
Coastal ports and desalination plants present highly corrosive marine environments. Acereare conducts rigorous salt spray testing (72 hours on full assemblies, 48 hours on sub-assemblies) to ensure that the internal mechanism, moving contacts, and electronic components remain unaffected by ocean air.
For installations in high-altitude mines (exceeding 2,000m) and dusty outback locations, our circuit breakers incorporate specific derating factors and high-grade IP protections. This prevents particulate accumulation from causing catastrophic tracking faults inside the arc chute.
Summer in Western Australia and Northern Territory regularly pushes switchboard enclosures to 50°C-55°C. The ARM3E is calibrated and tested using thermal-insulated materials and low-impedance copper conductors to ensure stability at elevated temperatures without thermal drift.
Integrating primary breakers with remote actuation, mechanical safety interlocks, and high-purity stamped assembly components.
Thick silver-plated contact surfaces optimize electrical conductivity and withstand thousands of switching operations under full load.
Standard modular frame size tailored for quick mounting on DIN rail or switchboard backplates. Ideal for industrial light poles.
Cost-effective alternative for simpler power loops that do not require adjustable electronic micro-processor controls.
Designed for quick system parameters calibration during on-site commissioning by Australian licensed electrical contractors.
Acereare's physical manufacturing infrastructure spans two specialized factories. We utilize automated production lines alongside computerized calibration rigs to eliminate human error.
Our quality control flow leverages integrated ERP and MES systems to track every molded case circuit breaker from initial raw metal stamping to raw resin injection molding, final coil winding, and assembly testing. Every single unit undergoes rigorous high-voltage dielectric testing and trip curve verification before shipment.

Yes. The ARM3E Series has been strictly engineered, manufactured, and tested in accordance with international standard IEC 60947-2, which is identical to the Australian standard AS/NZS 60947.2. Test reports detailing electrical insulation, temperature rise limits, and short-circuit making/breaking performance can be supplied upon request.
Electronic trip units use current transformers and microprocessors to monitor currents, ensuring they are immune to high ambient temperatures (up to 55°C) common in Western Australia mine sites. Conversely, thermal-magnetic breakers rely on bimetal strips that can trip early when switchboard internal temperatures rise. Additionally, the electronic ARM3E allows precise configuration of LSIG curves, enabling tight coordination with upstream utility fuses.
