Himel HDB3VR Earth Leakage Circuit Breaker (RCCB) Series | 30mA Human Protection, 6kA, AC Type, 2P & 4P Residual Current Range

Himel HDB3VR Earth Leakage Circuit Breaker (RCCB) Series represents the professional standard for highly reliable, budget-optimized residual current and shock protection in residential consumer units and commercial distribution networks. Purpose-built to instantly detect minute grounding faults and dangerous current leakages, this high-precision series features an instantaneous 30mA high-sensitivity trip threshold. It is engineered to mechanically break the electrical connection within milliseconds of a fault condition, providing a definitive defense to human life against accidental direct contact and fatal electrical shocks.

Manufactured under the global engineering oversight of Schneider Electric, the HDB3VR RCCB range is available in both 2-Pole (2P) single-phase and 4-Pole (4P) three-phase profiles, spanning all standard installation current ratings including 25A, 40A, and 63A. Calibrated to full Type AC parameters, this modular range is masterfully optimized to track traditional sinusoidal alternating residual currents, making it the perfect choice for everyday domestic appliance loops, corporate office socket rings, and general lighting circuits. Boasting a robust 6kA conditional short-circuit resilience conforming to IEC/EN 61008-1, this series delivers uncompromised safety and consultant-approved code compliance at an unmatched price point across new Egyptian construction sectors.

Comprehensive Range Configurations & Sizing:

• 2-Pole (2P / Single-Phase) Models: The default engineering layout to serve as the primary human-safety shield for individual apartments, office floors, and retail storefronts.

• 4-Pole (4P / Three-Phase) Models: Designed to protect entire three-phase domestic distribution panels, villa incoming boards, and commercial sub-panels.

• 25A, 40A & 63A Current Frameworks: Flexible matching options calibrated to align perfectly with upstream main circuit breakers, preventing thermal aging under heavy continuous duty.

Key Technical Advantages:

• 30mA High-Sensitivity Life Protection: Instantaneous magnetic tripping isolates lethal shock currents long before they can cause human cardiac failure.

• Type AC Leakage Monitoring: Calibrated explicitly for monitoring standard sinusoidal alternating currents within modern commercial and housing structures.

• Integrated Front Testing Button: Features a prominent mechanical "T" test button faceplate to ensure rapid, error-free periodic testing by maintenance crews or end-users.

• Perfect HDB3w Series Alignment: Matches the profile, physical dimensions (18mm per module), and aesthetics of Himel miniature circuit breakers (MCBs) for highly organized panel assembly.
