ABB 2P 63A 300mA RCCB (FW202) – Residential

The ABB FW202 63A-300mA is a 2-pole (2P) Residual Current Circuit Breaker designed for residential main incomer applications. As a Type AC device, it monitors current balance in 230V systems to provide immediate earth leakage protection. This 36mm wide unit is engineered in Italy and complies with IEC 61008 1 and IS 12640 standards for home safety.

Quick Answer

Absolutely, invest in the ABB FW202 63A 300mA RCCB if your priority is advanced fire safety for your residential main power supply. This Italian-engineered 2P device offers critical 300mA earth leakage detection, specifically designed to prevent heat buildup and potential electrical fires in Indian homes. Its 10kA breaking capacity ensures reliability during severe faults.

✓Prevents residential fires from insulation faults — 300mA residual current sensitivity triggers shutdown.
✓10kA conditional short circuit rating — withstands high fault currents when used with a backup MCB.
✓Ensures reliable operation over time — mechanical endurance tested for 10,000 cycles.
✓850°C glow wire test compliant housing — fire-retardant material exceeds UL94 V-2 standards.
✓Simplifies routine safety checks — prominent yellow test button for monthly verification.
✓1W power loss per pole — energy-efficient design reduces heat buildup inside the distribution board.

Opt for the ABB FW202 63A 300mA RCCB if you seek a robust, fire-protective main incomer solution for your Indian residence, offering superior earth leakage detection to prevent electrical fires. However, avoid this model if your primary need is personal shock protection, which typically requires a 30mA sensitivity device.

Engineering Analysis
The 300mA sensitivity is specifically chosen for fire protection as it detects leakage levels that can lead to heat buildup without causing nuisance tripping from small electronic leaks. With a 10kA breaking capacity, this device maintains structural integrity during severe faults when coordinated with an upstream MCB. The 2P configuration provides a solid neutral connection, ensuring the entire residential circuit is isolated during a leakage event.
