Designed to deliver robust electrical protection across Greek residential, commercial, and solar PV distribution networks under high thermal ambient conditions.
Greece’s power distribution landscape is undergoing an unprecedented modernization shift. Driven by the National Energy and Climate Plan (NECP), Greece aims for solar and wind energy to account for over 80% of its electricity generation by 2030. This rapid expansion of distributed energy resources (DERs)—from rooftop photovoltaic arrays in Attica to utility-scale solar farms in Thessaly—imposes stringent demands on low-voltage circuit protection components.
Wenzhou OFA Electrical Technology Co., Ltd. supplies the flagship OFL7 Series Miniature Circuit Breakers (MCBs) specifically adapted for the Mediterranean climate. Operating under high thermal stress, intense UV exposure, and saline coastal environments typical of the Aegean and Ionian islands, electrical protection devices require superior dielectric insulation, anti-corrosive contact metallurgy, and precise thermal-magnetic tripping mechanisms compliant with IEC/EN 60898-1 and IEC/EN 60947-2 standards.

Engineering precision designed for high breaking capacity, rapid arc quenching, and absolute operational longevity.
The OFL7 Series incorporates calibrated bimetallic elements for precise overload protection alongside an electromagnetic coil system for instantaneous short-circuit tripping. Available in B, C, and D tripping curves, it seamlessly matches resistive residential lighting loads, commercial inductive motor networks, and high inrush current solar inverter systems.
Featuring a 12-plate arc chute chamber combined with silver-alloy contacts, the OFL7 rapidly quenches electric arcs within milliseconds during fault conditions. This drastically reduces thermal stress on connected cables and prevents upstream transformer trips across Hellenic distribution boards.
Molded from high-grade flame-retardant VO polycarbonate materials, the enclosure withstands glow-wire tests up to 960°C. It exhibits exceptional resistance to salt mist corrosion, high ambient humidity, and thermal derating in temperatures exceeding 45°C.
OFA Electrical components deliver systematic power protection across public infrastructure, tourism hospitality, solar parks, and residential sub-distribution boards.
With Greece ranking among the top European nations in solar power generation per capita, OFL7 2P and 4P breakers are heavily integrated into AC combiner boxes, protecting string inverters against grid voltage spikes and reverse overcurrents in agricultural regions like Peloponnese and Central Macedonia.
Greek island hotels (Cyclades, Dodecanese, Crete) operate complex microgrids combining diesel backup, PV generation, and seawater desalination plants. OFL7 breakers paired with OFA RCCB/RCBO devices provide non-stop service continuity and zero-leakage human safety.
As Piraeus and Thessaloniki ports upgrade to green shore-power electric networks and EV charging infrastructure expands across national highways, OFA's heavy-duty MCCB and MCB solutions safeguard fast DC and AC charging pillars against heavy load surges.
Founded in 2013 and headquartered in Yueqing, Wenzhou—the world-renowned capital of China’s electrical appliance industry—Wenzhou OFA Electrical Technology Co., Ltd. specializes in the technical R&D, automated manufacturing, and global supply of distribution switchgear, control equipment, and protective accessories.
Upholding a strict philosophy of "Pragmatic Innovation, Uncompromised Quality, and Transparent Partnership," OFA has been awarded a Tax Credit Grade A rating for seven consecutive years. Backed by ISO9001 quality management systems, our digital inspection stations execute 100% full-inspection SOPs covering mechanical trip life, temperature rise limits, and insulation dielectric withstand testing before every shipment.
Empowering Greek electrical wholesalers, EPC contractors, and panel builders with integrated end-to-end power distribution systems.
Instead of isolated component supplying, OFA delivers total system topology planning. We combine OFL7 MCBs with high-capacity MCCBs (up to 630A) and ACB main breakers to construct robust, cascade-coordinated distribution networks from transformer secondary sides down to end-user sockets.
Aligned with Europe's smart grid push, OFA is evolving the OFL7 Series to support smart metering auxiliaries, remote motorized operators, and IoT communication gateways (RS485 Modbus/Wi-Fi), facilitating real-time remote fault diagnosis for unmanned island solar facilities.
Our Yueqing smart factory utilizes low-carbon assembly lines, zero-lead silver-tin-oxide (AgSnO2) contacts, and 100% recyclable halogen-free thermoplastics, directly contributing to EU RoHS and REACH environmental compliance.
Explore our full portfolio of MCBs, MCCBs, and protective components engineered for the Hellenic market.
Ensuring absolute alignment with Hellenic Organization for Standardization (ELOT) and European Union directives.
All OFL7 Miniature Circuit Breakers strictly conform to IEC/EN 60898-1 (for household and similar installations) and IEC/EN 60947-2 (for industrial low-voltage applications). They carry full CE marking, ensuring compliance with the European Low Voltage Directive (LVD 2014/35/EU) and Electromagnetic Compatibility (EMC 2014/30/EU). Furthermore, OFA components meet the electrical installation specifications mandated by ELOT HD 384 / HD 60364 across the Hellenic Republic.
OFA enforces a comprehensive quality inspection protocol. Every batch of OFL7 circuit breakers undergoes thermal trip calibration, 2.5kV impulse withstand voltage testing, contact resistance measurement, and automated mechanical operation checks. We support our Greek distributor partners with transparent factory test certificates (Type Test Reports) and a standard multi-year product warranty.
