ABB 2P 40A 30mA RCBO (DS201-C40/0.03) – Residential

03 is a 40A, 2-pole (1P+N) Residual Current Breaker with Overcurrent protection designed for residential final circuits.Manufactured in Italy, this device provides essential protection against earth leakage, overloads, and short circuits in a compact 2-module width.

Quick Answer

Absolutely, the ABB DS201-C40/0.03 is an excellent choice for modern Indian homes. It consolidates critical 30mA earth leakage, overload, and short-circuit protection into one compact 2-pole unit, ensuring maximum safety for personnel and appliances. Its 6kA breaking capacity and instantaneous tripping make it a robust solution for enhancing electrical safety in residential final circuits across India.

✓Ensures life-saving reaction times — instantaneous tripping at 30mA sensitivity occurs in ≤300ms at 1× Idn.
✓6kA Breaking Capacity — manages high-energy short circuits safely to prevent damage to your distribution board.
✓Compact space-saving design — 36mm (2 modules) unit width integrates both MCB and RCCB functions on a 35mm DIN rail.
✓Tested for long-term durability — mechanical endurance of 20,000 cycles ensures years of reliable switching.
✓Clear visual diagnostics — features a dedicated trip indicator and a yellow test button for routine safety checks.
✓Withstands harsh voltage spikes — 4kV impulse withstand rating protects the internal mechanism from grid surges.

Purchase the ABB DS201-C40/0.03 if you require top-tier, all-in-one electrical safety for your Indian residence, offering robust protection against common faults. Avoid if your application is industrial, requires specific higher current ratings, or non-residential trip characteristics beyond 30mA Type AC personnel protection.
