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

Opt for the Havells DHRGCTDF030025 if you prioritize robust human life protection against electrical shocks in your 240V residential setup. This 2P 25A 30mA RCCB precisely monitors earth leakage, tripping instantly to safeguard occupants. It's an essential safety upgrade, provided an upstream MCB handles overload/short circuits.

✓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 RCCB is ideal for homeowners prioritizing critical earth leakage protection in residential circuits, especially when installing a new or upgraded electrical panel. Avoid if you require integrated overload/short circuit protection, as this 2P 25A 30mA device must be coordinated with a separate upstream MCB.

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.
