Himel HDB9H Miniature Circuit Breakers (MCB) Series | 2-Pole, 10kA, C Curve, High Breaking Capacity Single-Phase Range

Himel HDB9H 2-Pole 10kA C Curve Miniature Circuit Breaker (MCB) series delivers specialized, high-fault current protection for premium commercial, infrastructure, and heavy industrial single-phase applications. Engineered to disconnect both the Phase and Neutral lines concurrently, this dual-pole range guarantees complete, uncompromised electrical isolation during severe fault conditions. The series encompasses all standardized current ratings extending from 6A up to 63A, providing a robust safety envelope for high-density modern installations.

As a high-spec commercial brand under the global stewardship of the Schneider Electric group, Himel engineers the HDB9H 2P series with reinforced internal arc-chutes and ruggedized, heat-resistant housings. Featuring a certified 10,000A (10kA) breaking capacity under IEC/EN 60898-1, this range is purpose-built to withstand massive short-circuit energies close to main distribution transformers. The versatile C-Curve trip profile handles moderate inductive inrush surges flawlessly—making it the definitive choice for use as a high-reliability main incomer for commercial sub-panels, server rooms, medical labs, and central HVAC single-phase compressor circuits throughout Egypt's 2026 infrastructure boom.

Comprehensive Range Applications:

• 6A, 10A & 16A Models: High-fault protection for industrial control loops, mission-critical instrumentation, and PLC panels.

• 20A & 25A Models: Dedicated dual-pole protection for commercial server racks, administrative office main lines, and high-end medical equipment.

• 32A & 40A Models: Safe circuit control for heavy-duty single-phase industrial pumps, ventilation arrays, and commercial kitchen lines.

• 63A Models: The engineering standard for a 10kA Main Incomer (مفتاح عمومي) in commercial properties, shopping malls, and institutional distribution boards.

Key Technical Advantages:

• 10kA High-Fault Interruption: Safe isolation of heavy short circuits near main substation transformers.

• Simultaneous 2-Pole Switching: Concurrently breaks Phase and Neutral to eliminate risk from floating neutral or residual return currents.

• Schneider Quality Pedigree: Co-engineered under rigorous quality systems to ensure an extended electrical and mechanical duty lifecycle.

• Front-Face Status Windows: Integrated visual flag indicators allow field technicians to identify faulted lines instantly during maintenance.
