Himel HDB9H Miniature Circuit Breaker HDB9H63A3C40 | 3P, 40A, 10kA High Breaking Capacity

Himel HDB9H63A3C40 is a professional-grade 3-pole Miniature Circuit Breaker (MCB) engineered for superior protection in demanding industrial three-phase systems. Rated at 40A with a robust 10kA breaking capacity, this breaker is a top-tier flagship of the HDB9H premium series. It is specifically designed to safeguard high-performance industrial motors, large central air conditioning units, and power distribution for heavy machinery where industrial-strength resilience is a non-negotiable safety requirement.

Developed under the global engineering standards of the Schneider Electric group, the HDB9H63A3C40 offers double the interruption capacity of standard residential breakers. Its C-Curve trip characteristic is perfectly calibrated for inductive loads, preventing nuisance tripping during the startup of 30 HP motors while ensuring immediate response to electrical faults. For Egyptian contractors seeking international IEC 60898-1 reliability and high short-circuit resilience at a market-leading price, this 3-pole 10kA breaker is the definitive choice for modern infrastructure.
