Optimized for high-altitude photovoltaic installations, these breakers deliver class-leading breaking capacities and reliable insulation coordination up to 1500VDC.
Argentina is undergoing a deep structural diversification of its energy matrix. Led by utility-scale PV developments in the high-altitude Northwest provinces like Jujuy, Salta, and Catamarca (most notably the Cauchari solar plants situated at over 4,000 meters above sea level), and wind generation in windswept Patagonia, the requirement for robust direct current (DC) safety infrastructure has risen exponentially. Traditional electrical components fall short in these demanding environments where atmospheric pressure is low, and thermal fluctuations span up to 40°C in a single day.
Moreover, critical oil & gas developments in the Vaca Muerta basin require advanced circuit protection components that conform to IEC/IRAM standard guidelines and ensure maximum uptime. In these applications, Molded Case Circuit Breakers (MCCB) must guarantee continuous operation at high duty cycles. For solar energy plants, low ambient pressure decreases the insulation properties of air, requiring custom derating curves and increased electrical clearances—parameters that our high-voltage DC MCCB series natively accommodates.

Founded officially in 2015, Acereare Electric encapsulates the industrial mastery of "RuiRui Electric" and "KeRui Electric" (two wholly-owned subsidiaries), drawing on over 20 years of family-owned craftsmanship in power distribution components.
As a top-tier Original Design Manufacturer (ODM) and OEM in China, Acereare operates state-of-the-art production environments dedicated to molded case circuit breakers (MCCB), air circuit breakers (ACB), and precision internal mechanisms. Our core competitive advantage lies in our end-to-end integration: from raw material formulation and sheet metal stamping to custom circuit board layout and automated product validation.
Our engineering team continuously extends the operating boundary of DC MCCBs to reduce systemic losses in utility solar arrays and battery energy storage complexes.
As PV central inverters switch from 1000V systems to 1500V topologies to realize cabling economies, the requirements on DC MCCBs become significantly more stringent. Breaking an electric arc in direct current is inherently more complex than in alternating current because DC does not have a natural zero-crossing point. To resolve this, our ARM6DC series incorporates specialized multi-slot arc-extinguishing chambers, powerful permanent magnets to drive the arc into the splitter plates, and heavy-duty contact materials that resist erosion over thousands of switching operations.

From the maritime ports of Buenos Aires to remote high-altitude wind projects, our breakers are built to withstand the harshest environments.
Specifically rated for solar projects at altitudes exceeding 2000 meters. The customized clearances prevent flashovers caused by thinner air, with custom derating coefficient matrices supplied to installers.
Utilizing high-performance low-temperature structural polymers and specialty non-freezing lubricants, our MCCBs operate down to -40°C, crucial for Andean solar valleys and Patagonia wind corridors.
For applications in port substations like Bahía Blanca and Rosario, the MCCB enclosures and internal metal mechanisms undergo 72-hour and 48-hour salt spray testing to prevent atmospheric oxidation.
Engineered for high-temperature desert regions in Northern Argentina, the breaker components are validated in internal environmental chambers at +55°C to avoid erratic nuisance tripping.
Integrated edge telemetry measures voltage, load current, and contact wear parameters. Connects natively with industrial SCADA systems via Modbus or Ethernet protocols.
High-reliability modular and molded case breakers that provide short-circuit and overcurrent protection to residential buildings, hospital complexes, and shopping malls across urban hubs.
Navigating Argentina's regulatory environment requires an experienced partner. We provide the requisite test documentation to speed up localized approvals.
In Argentina, electrical products must align with safety resolutions overseen by ENRE and certified through accredited bodies such as IRAM. Our manufacturing facility complies strictly with international standard ISO 9001:2015, and all electrical breakers carry comprehensive test certificates matching IEC 60947-2 specifications. Our specialized international operations team ensures that all shipments destined for Buenos Aires ports or inland projects are furnished with clean bills of lading, detailed HS code categorization, and country-of-origin documentation to streamline customs procedures and minimize logistics delays.
Our manufacturing philosophy relies on digital continuity. By integrating product engineering through Product Lifecycle Management (PLM) systems directly into our Enterprise Resource Planning (ERP) and Manufacturing Execution Systems (MES), we trace the lifecycle of every breaker back to the raw copper, steel, and silver-nickel contacts.
With over ten automated and manual assembly lines operating across our two production facilities, we manage bulk wholesale volumes while remaining flexible enough to construct customized specifications. Our internal QA laboratory houses over 150 dedicated testing instruments—including temperature rise testers, mechanical life calibrators, and precision tripping threshold detectors—guaranteeing that every product shipped to Argentina is validated for reliability before dispatch.
From customized logo laser marking to bespoke structural housings, we offer a clean, milestone-driven integration process for Argentine distributors and project developers.
