ABB 4P 63A 100mA ELCB (FW204) – Residential

The ABB FW204 63A-100mA is a 4P voltage-operated ELCB specifically engineered for the main incomer of residential distribution boards. This 400V Italian-made device provides critical earth leakage protection, ensuring a solid neutral connection across its 4-module width.

Quick Answer

Yes, you should buy the ABB FW204 ELCB if your Indian home requires robust 4-pole earth leakage protection at the main incomer. Its 100mA sensitivity prioritizes fire prevention, effectively minimizing nuisance tripping often encountered with lower sensitivities in typical residential setups, ensuring stable power. This 63A Italian-engineered device provides reliable safety against severe electrical faults.

✓Prevents electrical fires by detecting low-level leakage — 100mA Type AC residual current sensitivity.
✓10kA short circuit capacity ensures the device survives significant fault currents without internal failure.
✓Rapidly disconnects power during a ground fault — instantaneous tripping occurs in ≤300ms at 1× Idn.
✓63A rated current supports heavy residential loads across its compact 4-module DIN rail footprint.
✓Withstands high-voltage transients for enhanced durability — 4kV impulse withstand voltage rating.
✓IP20 rated housing protects internal components from solid objects larger than 12.5mm during daily operation.

This ABB FW204 ELCB is perfect for Indian residential main incomers needing 100mA fire prevention and nuisance-free operation. Buy for robust stability. Avoid if 30mA personal shock protection is paramount or for non-incomer use.
