ABB 4P 63A 30mA ELCB (FW204) – [Home Safety]

The ABB FW204 63A-30mA is a 4-pole voltage-operated ELCB engineered for high-sensitivity earth leakage detection in residential settings. It manages a rated current of 63A and is designed for installation at the main incomer to provide foundational safety against residual currents.

Quick Answer

Yes, you should consider the ABB FW204 ELCB if foundational life-saving earth leakage protection is your priority for a residential main supply in India. Its 30mA sensitivity offers rapid tripping (≤40ms) essential for protecting against fatal shocks. This 4-pole, 63A unit is crucial for ensuring household safety and meeting critical electrical standards.

✓Safeguards residents from direct contact shocks — 30mA sensitivity for high-precision leakage detection.
✓Handles high-demand residential loads — 63A rated current supports multiple heavy appliances.
✓Rapid response during electrical faults — instantaneous tripping clears leakage currents in ≤300ms.
✓Energy Limiting Class 3 rating — optimizes protection by limiting let-through energy during faults.
✓Resilient in extreme environmental conditions — maintains functionality from -25°C to +55°C.
✓Halogen-free and flame-retardant housing — UL94 V 2 flammability rating for enhanced fire safety.

This ABB FW204 ELCB is ideal for Indian homeowners prioritizing robust main incomer earth leakage safety, especially where high sensitivity (30mA) is non-negotiable for protecting lives. Avoid if seeking an RCCB for current-operated protection; this is a voltage-operated ELCB.
