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 Indian homeowners seeking dedicated fire and earth leakage protection at their main distribution board. Its 100mA sensitivity prevents nuisance tripping while ensuring critical fault isolation. This ELCB provides robust safety, essential for safeguarding your electrical system and property.
✓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.
For Indian homes seeking main incomer fire and earth leakage protection, this Havells ELCB's 100mA sensitivity is ideal, preventing nuisance trips. If direct 30mA human shock protection is needed for wet zones, an RCCB is the more appropriate choice.
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.
