The ABB DS301C-C25/0.03 is a 25A, 1P+N RCBO designed for residential final circuit protection. It combines earth leakage, overload, and short circuit protection into a single 18mm wide module. This Italy-made device is engineered for 230V systems within a 180–264V range.

Quick Answer

Yes, consider the ABB DS301C-C25/0.03 for robust protection in your Indian residential setup. Its crucial 30mA sensitivity offers instantaneous human life protection against electrical shocks, while the 6kA breaking capacity ensures safe interruption of high-fault currents. Integrating earth leakage, overload, and short-circuit functions into a compact 18mm module, this Italian-engineered RCBO provides comprehensive final circuit safety tailored for 230V systems.

✓Instantly disconnects power during earth faults — 30mA Type AC residual current sensitivity
✓Rated for 25A continuous load — allows for multiple appliance connections on a single residential circuit
✓Protects against high-intensity short circuits — 6kA breaking capacity for safety
✓Trips in less than 40ms at 5x rated leakage — provides rapid protection against severe electrical shocks
✓Halogen-free and flame-retardant construction — 850°C glow wire test rating for fire safety
✓Fits standard 35mm DIN rails — compact 1 module width saves valuable panel space

Indian homeowners prioritizing advanced 230V residential circuit protection should choose the ABB DS301C-C25/0.03 for its integrated 30mA life-saving and 6kA fault clearance. Avoid if seeking basic, non-integrated protection or industrial-grade solutions; this unit is tailored for comprehensive home safety.

Engineering Analysis
The 30mA sensitivity is vital for life safety, as it trips instantaneously during leakage to prevent cardiac arrest. A 6kA breaking capacity ensures the device can safely interrupt high-fault currents at the distribution point, while the switched neutral poles provide complete isolation. The Type C trip curve is optimized for residential loads that experience moderate inrush currents.
