Schneider 2P 16A 100mA RCBO (A9D72616) –

The Schneider Electric A9D72616 is a 16A, 2P (1P+N) RCBO designed specifically for residential final circuit protection. This device integrates earth leakage protection with a 100mA sensitivity alongside standard overload and short circuit safety. It functions as a critical safety barrier, installed on a 35mm DIN rail to provide instantaneous tripping during electrical faults.

Quick Answer

Absolutely, you should consider the Schneider A9D72616 if prioritising enhanced fire safety for your Indian residence. This 16A 2P RCBO offers crucial 100mA Type A earth leakage protection, specifically targeting hidden faults that could cause electrical fires, surpassing basic overload protection. Its 6kA breaking capacity ensures robust performance against significant electrical surges, making it a vital upgrade for modern homes seeking peace of mind.

✓Protects your family from fire hazards — 100mA sensitivity trips in ≤300ms at 1x Idn.
✓6kV impulse withstand voltage protects sensitive electronics from sudden atmospheric surges.
✓Occupies minimal space in distribution boards — 18mm width allows for high-density wiring.
✓6kA breaking capacity manages high-energy faults to prevent enclosure damage.
✓Switched neutral pole ensures total circuit isolation — Type A protection handles pulsating DC components.
✓Screw terminals support flexible wiring — accommodates 1-10 mm² rigid or 1-6 mm² flexible cables.

Opt for the Schneider A9D72616 if your primary concern is robust fire protection from earth leakage in residential circuits, especially in India where such safety is paramount. Avoid if your immediate priority is direct human shock protection requiring a 30mA sensitivity, as this 100mA unit is tailored for equipment and fire safety.
