Havells 2P 25A 30mA RCCB (DHRGCTDF030025) – Home

The Havells DHRGCTDF030025 is a 2P (2-Pole) 25A RCCB with 30mA sensitivity, designed specifically as a current-operated protection device for residential final circuits. This Type AC device operates at 240V and monitors the current balance to provide immediate earth leakage protection without integrated overload or short circuit functions.

Quick Answer

Absolutely, you should buy the Havells DHRGCTDF030025 if your priority is critical earth leakage protection for residential final circuits. This 2P 25A 30mA RCCB instantly trips at a dangerous 30mA current, ensuring human safety from electric shocks. Remember it's a dedicated earth leakage device and requires an upstream MCB for comprehensive overload and short-circuit protection. It's an indispensable component for any safe electrical installation.

✓Stops lethal shocks instantly — 30mA sensitivity trips power in less than 300ms.
✓Rated for 25A continuous current — 500A making/breaking capacity handles initial load surges.
✓Fits standard enclosures — 35mm DIN rail mounting with a slim 2-module (36mm) width.
✓6kA conditional short circuit rating — ensures durability during downstream fault events.
✓Built for longevity — mechanical endurance certified for 10,000 cycles and 4,000 electrical cycles.
✓Flame-retardant construction — UL94 V-2 flammability rating and 850°C glow wire test compliance.

This Havells DHRGCTDF030025 RCCB is perfect for Indian homeowners and electricians seeking dedicated 30mA earth leakage protection in residential setups, safeguarding against electric shocks. Avoid if you need integrated overload/short-circuit protection; it mandates an upstream MCB for full circuit safety.

Engineering Analysis
A 30mA residual current rating is the safety benchmark for human life protection because it interrupts current before it reaches levels capable of causing respiratory paralysis. The 6kA conditional short circuit capacity provides robust fault endurance when coordinated with an upstream MCB, while the 500A making/breaking capacity manages the high inrush currents typical of household electronics. The 2P configuration ensures a solid neutral connection, vital for maintaining a reference point in 50Hz residential systems.
