Specially customized for Oman’s high-temperature grid infrastructure, utility-scale photovoltaic installations, and industrial control systems.
The Sultanate of Oman is experiencing a paradigm shift in its electrical power distribution landscape. Driven by Oman Vision 2040, national economic strategies are prioritizing renewable energy integration (targeting 30% renewable capacity by 2030), mega industrial zones such as the Special Economic Zone at Duqm (SEZAD), and intense downstream petrochemical infrastructure expansion managed by entities like PDO (Petroleum Development Oman) and OQ.
Deploying electrical equipment in Oman demands exceptional hardware durability. Ambient temperatures frequently cross 50°C during summer months, with internal metal distribution panel enclosures reaching 70°C to 80°C under direct sun exposure in regions like Nizwa, Ibri, and Sohar. Furthermore, fine sand particles (airborne dust storms) and high coastal salinity in cities like Muscat and Salalah pose severe risks of thermal breakdown, dielectric degradation, and contact oxidation.
Standard low-voltage circuit breakers rated under IEC 60947-2 at 30°C or 40°C suffer up to 25% thermal derating in Oman's interior deserts. The OFA OF1 Series utilizes high-grade BMC (Bulk Molding Compound) flame-retardant thermoset housings, silver-alloy contact tips, and recalibrated bimetallic trip units to guarantee full rating stability up to 55°C ambient operational thresholds.
Comprehensive engineering parameters validating thermal resilience, arc quenching, and short-circuit interrupt performance under GCC environmental conditions.

DC currents do not have a natural zero-crossing point. The OF1 DC breaker series incorporates strong permanent magnetic blowouts that draw the electric arc instantly into high-density grid chute plates, extinguishing 1500V DC arcs within milliseconds.
Engineered with silver-graphene composite main contacts that reduce contact resistance by 35%. Internal heat generation is minimized inside outdoor panel boards under Oman’s brutal summer heatwaves.
Designed for integration into custom outdoor enclosures rated against fine silica dust (haboob sandstorms) and high moisture in coastal areas like Salalah during the Khareef monsoon season.
A Globally Recognized Low-Voltage Electrical Equipment Manufacturer Delivering High-Reliability Switchgear and Control Gear directly to the Middle Eastern Market.
Founded in 2013 and headquartered in Yueqing, Wenzhou—the acknowledged "Capital of Electrical Appliances in China"—Wenzhou OFA Electrical Technology Co., Ltd. stands as a premier manufacturer of power distribution switchgear, industrial automation devices, and renewable energy control solutions.
Upholding our core tenets of "Professionalism, Reliability, and Time-Tested Quality," OFA maintains complete vertical integration across product design, mold creation, precision stamping, automated assembly, and high-voltage dielectric testing. Operating under an ISO9001 certified quality management system, our factory delivers compliant products certified to international benchmarks including CE, IEC, CCC, and GCC regional norms.
We are proud to maintain a Tax Credit Grade A standing for seven consecutive years, earning deep-rooted trust from EPC contractors, panel builders, and electrical distributors across the Middle East, Southeast Asia, Europe, and South America.
Engineered deployment strategies for utility photovoltaic parks, oil & gas extraction sites, water desalination plants, and commercial smart real estate.
Oman’s expansive solar parks require combiner box components capable of handling high DC voltages up to 1500V DC without thermal fatigue. The OF1-250/PV and DCOF1-125/PV series deliver exceptional isolation and arc interruption, safeguarding string inverters and energy storage cabinets against reverse currents and insulation faults under scorching desert ultraviolet solar exposure.
Downstream petroleum extraction and refining plants demand non-sparking, explosion-safe control panels. OFA’s heavy-duty OFA OFM1 and BA88 Series MCCBs feature reinforced trip mechanisms and anti-vibration terminals that resist high physical mechanical shocks found in drilling rigs and hydrocarbon processing plants.
Modern developments across Greater Muscat, Sultan Qaboos Port waterfronts, and hospital complexes utilize OFA RCBOs (NB1L, OFMIN) and RCCBs (OFGX, OFPM). These units combine earth-leakage current protection with overcurrent protection in compact modular widths, preventing electrical fires and life-threatening ground fault shocks.
Reverse osmosis seawater desalination plants in Sohar and Salalah operate continuously in harsh, chemical-laden environments. OFA switchgear uses corrosion-resistant tin-plated copper busbars and anti-fungal insulation materials to maximize equipment lifecycle integrity.
