Engineered for maximum reliability under East Africa's harsh climatic conditions, grid fluctuations, and rapid solar adoption.
Navigating grid expansion, commercial solar PV growth, and industrial protection standards under EPRA and KEBS compliance.
Kenya is rapidly cementing its status as the commercial and industrial hub of East Africa. Driven by the government’s Vision 2030 development blueprint, massive investments are flowing into industrial parks in Ruiru, Naivasha Special Economic Zone, and Mombasa Port logistics corridors. Concurrently, the Energy and Petroleum Regulatory Authority (EPRA) has enforced rigorous standards for industrial grid integration and commercial power security.
However, Kenya’s electrical ecosystem faces unique operational hurdles. The mix of utility power (Kenya Power / KPLC), rapid integration of distributed solar PV, and heavy reliance on industrial diesel generators creates high harmonic distortion, frequent voltage transients, and unpredictable neutral shifts. Traditional low-cost AC circuit breakers frequently fail or experience nuisance tripping under these hybrid grid conditions.
The OFA OFID Series (comprising Type A and Type B Residual Current Operated Circuit Breakers / RCCBs and DC Molded Case Breakers) is engineered precisely to resolve these challenges. Incorporating advanced magnetic core alloys and high-sensitivity residual current monitoring circuits, OFID devices detect smooth DC leakage currents, pulsating AC, and high-frequency harmonics generated by modern solar inverters, variable frequency drives (VFDs), and EV chargers.
By delivering rapid tripping response times (<30ms) and elevated short-circuit breaking capabilities (up to 10kA–50kA), Wenzhou OFA Electrical Technology Co., Ltd. provides Kenyan factories, EPC contractors, and electrical panel builders with a field-tested, robust protection barrier.

Tailored protection architecture for agricultural processing, commercial real estate, solar energy, and infrastructure projects.
In Nairobi, Nakuru, and Eldoret, commercial solar rooftop installations are surging. The OFID 4P DC RCCB prevents inverter-induced direct current leakage from blunting main distribution transformers, protecting localized storage battery systems.
Agricultural processing facilities in Kericho and Kiambu operate continuous motorized heavy machinery under high humidity and dust. OFID 2P and 4P switchgears stop earth faults instantly, avoiding costly production line shutdowns.
Marine salt-spray environments cause insulation degradation. OFA’s tropicalized, anti-corrosive housing materials ensure long-term stability and eliminate tracking currents in coastal storage hubs and hospitality buildings.

Solar PV inverters naturally leak small amounts of direct current into the AC neutral and ground system. Standard Type AC residual current devices (RCDs) become 'blind' or saturated by smooth DC leakage currents, failing to trip during true earth fault hazards. The OFID 4P Type B DC breaker actively senses smooth DC currents and high-frequency AC faults, making it indispensable for EPRA-compliant solar microgrid projects across Nairobi and East Africa.
Yes. All OFA switchgears and OFID products comply strictly with international IEC standards (IEC 61008-1, IEC 60947-2) which align with KS IEC standards recognized by the Kenya Bureau of Standards (KEBS). We routinely provide test reports, CE certifications, and documentation required for Pre-Export Verification of Conformity (PVoC) inspection certificates for smooth customs clearance at Mombasa Port or JKIA Nairobi.
