High-performance Residual Current Circuit Breakers with Overcurrent Protection engineered for European industrial, commercial, and residential DIN-rail infrastructure.
Austria stands at the forefront of Central European industrial automation, green energy integration, and stringent grid safety protocols. As part of Austria's Mission 2030 climate and energy strategy, the country is rapidly accelerating its transformation toward 100% renewable electricity generation. This shift places unique demands on low-voltage distribution networks across Upper Austria, Styria, Tyrol, and Vienna.
Modern industrial plants, automotive supply chains in Graz, and high-altitude Alpine PV installations require electrical protection hardware capable of handling complex non-sinusoidal residual currents, severe ambient temperature fluctuations (-25°C to +70°C), and high harmonic loads.
The standard compliance baseline in Austria requires full alignment with ÖVE/ÖNORM E 8101 (Electrical Installations) alongside EN 61009-1 / EN 60898-1 international standards. The OFC Series product line, manufactured by Wenzhou OFA Electrical Technology Co., Ltd., is specifically engineered to meet these stringent Austrian operational realities, delivering superior short-circuit limiting performance, arc containment, and residual current protection.
Designed for industrial automation engineers, system integrators, and electrical panel builders in the DACH region.
The OFC Series incorporates high-precision electromagnetic trip mechanisms calibrated for B, C, and D tripping curves. This ensures instantaneous interruption under short-circuit conditions, reducing thermal stress on cable insulation across sensitive Austrian industrial automated production lines.
Featuring a 12-plate arc chute system, OFC circuit breakers split and extinguish electric arcs within milliseconds. This drastically lowers I²t energy pass-through, protecting downstream PLC controllers, industrial drives, and human operators from catastrophic fault damage.
Built according to standard EN 60715 35mm DIN-rail profiles, all OFC, OFKL, and NB1L series components allow effortless retrofitting into existing Rittal, Eaton, or Siemens distribution enclosures common throughout Austrian manufacturing facilities.
