Engineered for seamless DIN-rail integration, reliable thermal-magnetic tripping, and optimal overload protection across Saudi commercial and residential power distribution boards.
As the Kingdom of Saudi Arabia advances rapidly under the blueprint of Saudi Vision 2030, the city of Riyadh is witnessing an unprecedented expansion in urban infrastructure, mega-commercial complexes, smart data hubs, and industrial zones under the governance of MODON (Saudi Authority for Industrial Cities and Technology Zones). This massive infrastructure growth demands an uncompromising standard for low-voltage power distribution networks. Central to this electrical infrastructure is the protection of final sub-circuits against short-circuits and current overloads. The OFL7 Series Miniature Circuit Breaker (MCB) engineered by Wenzhou OFA Electrical Technology Co., Ltd. represents a benchmark in technical precision, thermal resilience, and electrical endurance designed specifically to address the demanding operating conditions of the Arabian Peninsula.
Electrical procurement in Riyadh demands strict compliance with Saudi Standards, Metrology and Quality Organization (SASO) directives and SABER platform registration. Low-voltage protective switchgear installed within the Central Province must adhere strictly to IEC/EN 60898-1 and IEC/EN 60947-2 standards, while matching the specific 220V/380V and dual-voltage transition standards enforced by the Saudi Electricity Company (SEC).
The OFL7 Series MCB has been rigorously type-tested to ensure seamless integration with local distribution board configurations, including surface-mounted metal enclosures (DBs), main distribution boards (MDBs), and sub-main distribution boards (SMDBs). Key environmental and physical stress factors considered during the design phase include:
The OFL7 Series spans single-pole (1P), two-pole (2P), three-pole (3P), and four-pole (4P) configurations, covering rated operating currents from 1A up to 63A. The unit is optimized for quick installation onto standard 35mm DIN rails, featuring dual-stable DIN-rail clips for hassle-free mounting and maintenance.

| Rated Voltage ($U_e$) | 230/400V AC (1P), 400V AC (2P, 3P, 4P), 50/60Hz | Fully compliant with KSA SEC grid frequency (60Hz) and nominal operating voltages. |
| Rated Short-Circuit Capacity ($I_{cn}$) | 6,000A / 10,000A (IEC 60898-1) | Ensures rapid arc extinction and breaker survival during heavy dead-short faults. |
| Tripping Curves | B Curve (3-5 $I_n$), C Curve (5-10 $I_n$), D Curve (10-14 $I_n$) | B curve for resistive loads; C curve for general building services; D curve for high-inductive motors/pumps. |
| Insulation Voltage ($U_i$) | 500V AC | Provides complete galvanically isolated protection during maintenance lock-out procedures. |
| Housing Material | Polyamide PA66, Flame Retardant (UL94-V0) | Self-extinguishing material prevents electrical fires in extreme overheat scenarios. |
| Terminal Connection Size | 1 to 25 $\text{mm}^2$ flexible/rigid cable | Accommodates standard copper conductor sizing mandated by KSA wiring regulations. |
The global low-voltage circuit breaker market is shifting rapidly toward intelligent, eco-friendly, and modular protection devices. Modern building management systems (BMS) require high data visibility, compact footprints, and hybrid protection combining Miniature Circuit Breakers with Residual Current Protection with Overcurrent (RCBO) and Arc Fault Detection Devices (AFDD).
Wenzhou OFA Electrical Technology Co., Ltd. is positioned at the forefront of this evolution. Our ongoing R&D roadmap emphasizes smart IoT-enabled MCBs capable of real-time temperature tracking, current leakage measurement, and remote automated tripping/resetting via wireless protocols.

Detailed technical answers for Saudi electrical contractors, procurement specialists, and panel builders.
A: The OFL7 Series miniature circuit breakers are fully compliant with international standard IEC/EN 60898-1 and carry CE certification. For Saudi Arabian imports, OFA provides full documentation support to facilitate SABER platform registration and issue the Certificate of Conformity (CoC) required by SASO customs regulations.
A: In Riyadh, panel interior temperatures often exceed 50°C to 55°C. OFA provides specific thermal compensation curves and derating factor tables for the OFL7 Series. By adjusting the bimetal thermal element or selecting appropriately recalibrated current ratings ($I_n$), we prevent false tripping while guaranteeing 100% magnetic protection during short-circuit events.
A: The OFL7 Series is available in B, C, and D tripping curves. B Curve (3-5 $I_n$) is recommended for electronic circuits and resistive heating; C Curve (5-10 $I_n$) serves as the standard choice for general commercial lighting, power outlets, and building services in Riyadh; D Curve (10-14 $I_n$) is specifically used for high inductive surge loads like heavy HVAC compressors, water pumps, and industrial motors.
A: An RCBO (such as the OFR1 or OFDPN series) combines residual current protection (earth leakage) and overcurrent/short-circuit protection into a single compact device. This reduces panel space by 50%, minimizes internal wiring work, eliminates potential terminal hot-spots, and provides independent circuit fault isolation—ensuring that an earth fault on one branch does not trip unrelated healthy circuits.
A: Yes. OFA specializes in flexible OEM/ODM manufacturing. We support custom front-plate laser printing (brand logo, part numbers, barcoding), customized color-coded toggle switches, customized box packaging, and language-specific instruction sheets (Arabic/English) tailored to Saudi market distributor requirements.
A: Standard product configurations maintain buffer component stocks, enabling quick production turnaround in 15-25 days depending on volume. Logistics options include sea freight to King Abdulaziz Port in Dammam or Jeddah Islamic Port, with inland transit to Riyadh, as well as expedited air freight directly to King Khalid International Airport (RUH) for urgent site requirements.
