The ABB FW204 40A-30mA is a 4-pole (4P) Residual Current Circuit Breaker specifically engineered for 400V residential electrical systems. Functioning as a main incomer, this 40A rated device monitors the 50 Hz current balance to provide dedicated earth leakage protection against sinusoidal alternating currents (Type AC).
Quick Answer
Yes, you should consider the ABB FW204 40A-30mA if you need robust earth leakage protection for a 400V residential electrical system in India. This 4-pole 40A RCCB offers instantaneous shock protection and is engineered for consistent performance and safety. Its compliance with IS 12640-1 and IEC 61008-1 standards makes it a technically sound and reliable investment for long-term home safety.
Choose the ABB FW204 40A-30mA for optimal earth leakage protection in residential 400V systems, especially if valuing high efficiency and long-term safety over initial cost. Avoid if your application demands capacities beyond residential scope or if seeking the absolute cheapest upfront installation without considering performance.
