Precision-engineered circuit protection products compliant with European IEC/EN 61009-1 and Belgian national installation codes.
As Western Europe accelerates its transition toward green energy grid structures and industrial electrification, Belgium occupies a pivotal strategic hub. From the heavy chemical clusters in the Port of Antwerp-Bruges to the green hydrogen distribution setups in Zeebrugge and Flanders' high-tech automation lines, electrical infrastructure requirements have evolved dramatically. The surge in distributed PV systems, commercial EV fleet charging networks, and heat pump integrations across Belgian residential and industrial sectors has imposed unprecedented operational stress on low-voltage distribution boards.
Belgian installations require absolute adherence to RGIE (Règlement Général sur les Installations Électriques / Algemeen Reglement op de Elektrische Installaties). The OFDPN 1P+N series guarantees dual-pole breaking security (phase disconnected with neutral switched), matching strict domestic and commercial safety protocols.
Modernizing Belgian electrical distribution panels (Coffret Électrique) often presents severe space constraints. Integrating overload, short-circuit, and earth-leakage protection into a single 18mm module width doubles enclosure density without sacrificing thermal dissipation stability.
With modern non-linear loads such as variable frequency drives (VFDs) in Wallonia factories and inverter-driven heat pumps, standard Type AC breakers trip incorrectly or blind. OFDPN series offers Type A and Type F magnetic release systems for high-frequency residual current immunity.
The OFDPN series engineered by Wenzhou OFA Electrical Technology Co., Ltd. represents an advanced generation of residual current operated circuit breakers with overcurrent protection (RCBO). Unlike standard 2P breakers that consume 36mm of DIN-rail space, the OFDPN packs total electronic earth-leakage monitoring and electro-magnetic thermal overload mechanisms into a 18mm single-module footprint.

Inside the OFDPN breaker core, high-grade silver-graphite contacts (AgC) minimize contact resistance and prevent welding during short-circuit faults up to 10kA. The arc chute assembly features a 12-plate splitter system that rapidly elongates, cools, and extinguishes electrical arcs within 3 to 5 milliseconds, dramatically suppressing pass-through energy ($I^2t$) and safeguarding underlying sensitive electronics in smart buildings.
Wenzhou OFA Electrical Technology Co., Ltd. supplies customized low-voltage distribution components optimized for the specific environmental and operational demands found throughout Belgium.
Around the Port of Zeebrugge and North Sea offshore grid landing stations, high humidity and saline atmospheres require exceptional insulation. OFDPN housing utilizes VO-grade anti-flaming polycarbonate materials with non-hygroscopic arc-chute walls to prevent tracking current breakdowns.
Belgian logistics hubs in Antwerp and Ghent are retrofitting massive wallbox charging banks. The OFDPN 2P40A RCBO provides 30mA Type A residual protection with high surge current immunity, preventing nuisance trips caused by high-capacity vehicle onboard chargers during initial plug-in state transitions.
In urban centers like Brussels, Leuven, and Liège, legacy distribution boards are overcrowded. Replacing outdated 2P standard breakers with OFDPN 1P+N compact modules allows system integrators to double circuit density without replacing the main enclosure, significantly lowering retrofitting labor costs.
Founded in 2013 and rooted in Yueqing, Wenzhou — the Capital of Electrical Appliances in China — Wenzhou OFA Electrical Technology Co., Ltd. has established itself as one of the professional suppliers of distribution switchgear and control equipment worldwide. Owning independent brands such as "OFA", our product range covers multiple industries including power systems, green energy, industrial automation, commercial construction, and equipment OEM manufacturing.
Adhering to honest, law-abiding operations, OFA has been rated as Tax Credit Grade A for seven consecutive years. Our engineering team combines solid R&D capabilities with continuous full-process type testing (mechanical life, temperature rise, dielectric breakdown, and tripping curve calibration) to output zero-defect component solutions at competitive price points.
Every single OFDPN breaker off our production line undergoes automated thermal-magnetic trip calibration, insulation resistance testing at 2500V, and high-current short-pulse contact verification prior to final packaging.
We provide comprehensive white-label manufacturing for Belgian electrical distributors, panel builders, and original equipment manufacturers (OEMs), including custom laser marking, custom tripping threshold tuning, and special packaging.
