Havells 2P 63A 100mA ELCB (DHRGCTDF100063) – Home

The Havells DHRGCTDF100063 is a 63A 2P voltage-operated ELCB designed for residential electrical safety in 240V systems.

Quick Answer

Yes, the Havells DHRGCTDF100063 is ideal for 240V Indian residential main distribution boards. Its 100mA sensitivity effectively prevents electrical fires from earth leakages without nuisance tripping, unlike more sensitive units. The robust 10kA breaking capacity ensures main incomer durability. For direct personal shock protection, requiring a 30mA device, this specific ELCB is not the primary choice.

✓Safeguards your property against fire risks — 100mA sensitivity detects dangerous leakage levels early.
✓Rated current of 63A handles heavy residential loads while maintaining a 10kA short circuit strength.
✓Protects sensitive electronics from power spikes — 4kV impulse withstand voltage ensures component longevity.
✓Energy Limiting Class 3 design restricts let-through energy during faults to protect downstream wiring.
✓Reliable mechanical operation over time — tested for 10,000 cycles of mechanical endurance.
✓Halogen-free and RoHS compliant construction ensures no toxic fumes during high-temperature 850°C glow wire exposure.

This Havells 2P 63A 100mA ELCB is perfect for Indian homeowners prioritizing main incomer fire safety and nuisance-free operation. It protects against major earth faults. Those needing direct human shock protection should instead opt for a 30mA RCCB for enhanced personal safety.

Product Overview
The Havells DHRGCTDF100063 is a 63A 2P voltage-operated ELCB designed for residential electrical safety in 240V systems. This device provides critical earth leakage protection by monitoring residual currents up to 100mA, utilizing a Type AC sensing mechanism to detect standard AC leakages. Installed primarily in distribution boards, it ensures the safe isolation of circuits when hazardous voltage potentials are detected.

Engineering Analysis
The 100mA sensitivity is specifically calibrated for fire protection in domestic circuits where higher leakage thresholds prevent nuisance tripping compared to 30mA units. A 10kA breaking capacity ensures the device survives high-energy faults at the main incomer, while the switched neutral in this 2P configuration provides total isolation during maintenance. The Energy Limiting Class 3 rating further enhances safety by restricting the total let-through energy during a short circuit event.
