Direct supply of precision Miniature Circuit Breakers (MCB) and Residual Current Operated Circuit Breakers (RCCB/RCBO) custom-calibrated for Hamburg's port, maritime, and industrial infrastructure.
As Northern Europe’s premier maritime logistics gateway and a vital hub for German industrial automation, the Free and Hanseatic City of Hamburg imposes stringent operational, thermal, and electrical safety standards on power distribution switchgear. The expansion of port electrification (including onshore power/cold ironing facilities), container terminal automation in Altenwerder and Altenwerder-Harburg, alongside large-scale green hydrogen projects in Wilhelmsburg, requires low-voltage switchgear that goes beyond standard commercial tolerances.
The OFGX Series Circuit Breakers—engineered by Wenzhou OFA Electrical Technology Co., Ltd.—represent a sophisticated technological convergence designed to satisfy these rigorous technical requirements. Built around high-density arc-extinguishing chambers, reinforced silver-alloy contacts, and precision bimetallic thermal-magnetic tripping mechanisms, the OFGX series delivers unyielding short-circuit interrupting capacities and earth-leakage sensitivity compliant with DIN VDE 0100-410 and international IEC 60947 / IEC 61008 standards.
Global procurement teams and EPC contractors across Northern Germany face three main structural challenges in power architecture deployment:
To provide clear information gain for technical directors, panel builders, and electrical consulting engineers in Hamburg, the structural specs of the OFGX family are detailed below against DIN VDE compliance benchmarks.
| Technical Parameter | OFGX MCB Standard | OFGX RCCB / RCBO (4P/2P) | German Market Benchmark (DIN VDE) |
|---|---|---|---|
| Rated Current ($I_n$) | 1A - 63A / 80A / 100A | 16A - 100A | 16A - 125A |
| Rated Short-Circuit Capacity ($I_{cn}$) | 6,000A / 10,000A (IEC 60898-1) | 10,000A with backup fuse | 6,000A - 10,000A Industrial |
| Tripping Curves | B (3-5 $I_n$), C (5-10 $I_n$), D (10-14 $I_n$) | Instantaneous / Selective Type S | Curve B/C standard distribution |
| Residual Current Sensitivity ($I_{\Delta n}$) | N/A | 10mA, 30mA, 100mA, 300mA | 30mA Personal Safety / 300mA Fire |
| RCD Operating Type | N/A | Type AC, Type A (Pulsating DC), Type B | Type A mandatory for domestic/commercial |
| Insulation Voltage ($U_i$) | 500V AC | 500V AC | 500V AC minimum |
| Mechanical / Electrical Endurance | 20,000 / 10,000 operations | 10,000 / 4,000 operations | IEC standard compliant |
Short circuit interruption within Hamburg's dense grid connections demands near-instantaneous contact separation. The OFGX architecture utilizes a 12-plate deionizing arc chute combined with a blow-out magnetic loop. When a fault current reaches the threshold, the magnetic field forces the electric arc off the silver contacts into the chute within 2.5 milliseconds, quenching high-voltage ionization before cumulative thermal energy causes enclosure failure or busbar shorting.
Response time below 0.04 seconds for 30mA earth leakage protection, safeguarding human life against contact voltage in humid docklands and maritime workshops.
Operates reliably across extreme temperature ranges from -25°C to +70°C, ensuring stability in non-climate-controlled logistics sheds and offshore substation control cabinets.
Standardized 18mm per pole modular width, fully compatible with standard 35mm DIN-rail distribution boards utilized throughout German distribution boards.
Container ships berthing at Hamburg Port require shore power connections. OFGX 4P residual current operated circuit breakers prevent earth leakage return currents through saltwater, protecting sensitive on-board transformer systems and shore-side power panels.
Commercial rooftop solar installations across Hamburg’s industrial parks demand Type A/B RCBO protection capable of handling DC residual current components from inverter stages. OFGX series ensures grid synchronization protection without nuisance tripping.
High-throughput automated warehouses in Hamburg-Harburg deploy hundreds of continuous electric drives. OFGX Miniature Circuit Breakers with D-curve characteristics easily absorb motor startup inrush currents without tripping prematurely.
For data centers in the Hamburg metropolitan area, power reliability is non-negotiable. OFGX 10kA breaker families provide selective protection coordination, isolating downstream sub-circuits while keeping primary feeder lines operational.
Founded in 2013 and situated in Yueqing, Wenzhou—the world-renowned capital of low-voltage electrical apparatus—Wenzhou OFA Electrical Technology Co., Ltd. has established itself as an authoritative manufacturer and global supplier of distribution switchgear, control equipment, and circuit protection devices.
With an engineered product spectrum ranging from Miniature Circuit Breakers (MCB), Molded Case Circuit Breakers (MCCB), Residual Current Circuit Breakers (RCCB/RCBO), to Air Circuit Breakers (ACB) and Isolator Switches (IS), OFA serves high-value clients across 50+ countries including Germany, Poland, Brazil, and Southeast Asia. The company adheres strictly to ISO9001 quality system management and maintains a 100% full-inspection SOP for every finished breaker before packaging.
