Himel HDB3w Miniature Circuit Breakers (MCB) Series | 3-Pole, 6kA, C Curve, Three-Phase Power Range

Himel HDB3w 3-Pole 6kA C Curve Miniature Circuit Breaker (MCB) series represents the industry benchmark for reliable, cost-effective three-phase circuit protection in modern residential, commercial, and light industrial buildings. Engineered to provide simultaneous mechanical tripping across all three live phases, this range protects vital downstream equipment from overloads, short circuits, and dangerous motor single-phasing conditions. The series covers all standardized current ratings extending from 10A up to 63A, offering an adaptable footprint for versatile panel designs.

As an essential value-engineered brand under the global stewardship of the Schneider Electric group, Himel designs the HDB3w 3P series to bridge the gap between high performance and strict project budget optimization in the Egyptian market. Featuring a certified 6000A (6kA) breaking capacity under IEC 60898-1, this series easily satisfies standard building electrical codes. Its universal C-Curve trip profile gracefully manages standard transient starting current surges—making it the ideal choice for safeguarding three-phase central air conditioners, standard elevators, multi-story distribution boxes, and light industrial water pump sets across modern Egyptian real estate developments.

Comprehensive Range Applications:

• 10A, 16A & 20A Models: Perfect for lower-power three-phase balancing circuits, small workshop machinery, and commercial lighting sub-distribution.

• 25A & 32A Models: Optimized protection for standard elevators, medium-sized central HVAC outdoor units, and commercial kitchen lines.

• 40A & 63A Models: The engineering standard for use as a Main Incomer (مفتاح عمومي) in multi-floor residential sub-panels, administrative offices, and retail showrooms.

Key Technical Advantages:

• Simultaneous 3-Pole Tripping: Breaks all three phases concurrently to prevent partial phase power loops and motor damage.

• 6kA Robust Short-Circuit Capacity: Certified to isolate high-intensity faults safely in commercial sub-distribution networks.

• Schneider Engineering Quality: Built to international quality protocols for an extended electrical and mechanical service lifespan.

• Standardized 18mm Per-Pole Footprint: Occupies exactly 54mm (3 modules) of DIN rail space for neat, ultra-organized panel building.
