Engineered to precise IRAM-IEC standards, offering modular 1P to 4P overload and short-circuit protection for high-density industrial and commercial boards across Argentina.
Addressing the complex macroeconomic, geographical, and technical realities of low-voltage electrical distribution in South America's second-largest economy.
Argentina’s electrical distribution framework, governed by regional entities like Edenor, Edesur, and provincial cooperatives (EPEC, EPEN), experiences notable voltage fluctuations, high ambient temperatures in northern regions (Gran Chaco, Salta), and severe harmonic distortions from expanding heavy industries. The OFNC Series Miniature Circuit Breakers (MCB) are specifically engineered with optimized bimetallic elements and high-grade arc chute chambers capable of operating continuously under extreme ambient variances (-35°C to +70°C derating supported).
Whether installed in urban commercial high-rises in Buenos Aires or remote agricultural processing sites in Rosario, electrical protection systems require superior breaking capacity (6kA to 10kA according to IEC/EN 60898-1 standards) to prevent catastrophic electrical fires and equipment damage during transient voltage surges.
The explosive growth of Argentina’s Lithium Triangle (Jujuy, Salta, and Catamarca) and massive solar power installations in the Cuyo region require industrial-grade switchgear capable of handling high DC and AC current stresses. High-altitude operations above 3,500 meters in the Andes impose lower air density, reducing traditional dielectric insulation strength.
Wenzhou OFA Electrical Technology Co., Ltd. supplies tailored OFNC series MCBs and complementary MCCBs featuring enlarged creepage distances, silver-alloy contacts (AgCdo/AgZnO), and reinforced thermosetting enclosures (UL94-V0 flame retardant), guaranteeing optimal operational stability in high-altitude mining substations and solar inverter combiner boxes.
Uncompromising engineering depth designed to deliver superior short-circuit current limitation and thermal overload protection.
The core mechanism of the OFNC Series relies on a 12-plate arc-extinguishing grid engineered from high-grade plated steel. During a high-current short circuit fault, the electromagnetic trip coil acts within 3 milliseconds, pushing the moving contact open. The resulting electric arc is immediately driven into the arc chute by magnetic blow-out plates, splitting and cooling the arc energy instantly to prevent contact welding.
Furthermore, our precision bimetallic thermal strips are calibrated using automated laser welding techniques, eliminating mechanical tolerances. This guarantees that whether under B, C, or D tripping characteristics, the circuit breaker strictly adheres to nominal trip curves without nuisance tripping caused by ambient heat accumulation inside panel boards.

Leveraging Yueqing’s world-class electrical cluster to supply Argentina with cost-effective, premium-grade switchgear components.
Founded in 2013 in Yueqing, Wenzhou, OFA operates at the epicenter of low-voltage component manufacturing. Our localized supply chain ensures instant access to high-purity copper, precision stampings, and raw materials, reducing lead times by up to 30% compared to Western suppliers.
Quality is non-negotiable. Every OFNC series circuit breaker undergoes automated calibration testing for thermal tripping, instant magnetic trip verification, dielectric withstand voltage tests, and contact resistance checks prior to packaging, holding a 7-year Grade A Tax Credit reputation.
We empower local Argentine distributors, panel builders, and importers by offering private labeling, customized laser printing, special tripping characteristic curve tuning, and flexible packaging designed to meet IRAM and Mercosur commercial requirements.
Engineering customized protection solutions from heavy industrial plants to rural electrification projects.
High-altitude, dusty, and chemically aggressive brine processing environments require resilient electrical gear. The OFNC 3P and 4P MCBs, combined with OFA Molded Case Circuit Breakers (MCCB BA88 / OFA-M1), provide main circuit and branch distribution protection inside hazardous processing skids, enduring wide temperature spans and severe vibration.
Argentina's booming utility-scale solar farms demand reliable AC/DC isolation and protection. The OFNC series, alongside our specialized DC RCCB (OFID 4P) and RCBO (OFMIN) series, safeguards string combiner boxes and inverter auxiliary power units against ground faults and transient overcurrent events under intense solar radiation.
Grain elevators, oilseed crushing plants, and food packaging lines require high-inrush motor protection. Utilizing OFNC Series D-Curve MCBs prevents false tripping caused by motor starting currents while maintaining absolute short-circuit protection for heavy conveyor systems and grain driers.
High-density residential and office buildings require space-saving DIN-rail mounted protection. OFNC 1P+N and 2P MCBs deliver compact layout footprints in consumer units, reducing enclosure sizes while satisfying strict local municipal building codes and IRAM electrical safety regulations.
Streamlining international procurement for Argentine importers, panel builders, and EPC contractors.
Procuring electrical components into Argentina involves navigating complex import frameworks (such as SIRA/SEDI declarations, customs clearance, and foreign exchange regulations). Wenzhou OFA Electrical Technology Co., Ltd. provides robust international trade support, including tailored commercial invoicing, precise HS Code classification (e.g., HS 8536.20 for Automatic Circuit Breakers), and flexible payment arrangements (T/T, L/C at sight).
Furthermore, all exported products are accompanied by full Type Test Reports (CE, IEC 60898-1, CB Scheme), facilitating seamless local certification alignment with IRAM standards. Our specialized ocean freight packaging features moisture-proof sealed polybags and reinforced corrugated master cartons stacked on ISPM-15 compliant fumigated pallets, guaranteeing pristine product arrival at the ports of Buenos Aires or Rosario.
