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, the ABB FW202 2P 63A 300mA RCCB is an indispensable choice for Indian residential main incomer applications. Its precise 300mA sensitivity specifically targets fire protection by detecting dangerous earth leakages before heat buildup occurs. Engineered in Italy with a 10kA breaking capacity, this device ensures robust, compliant safety for your home's critical electrical entry point.

✓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.

This ABB FW202 2P 63A 300mA RCCB is ideal for Indian homeowners prioritizing advanced fire protection at their main electrical incomer. It efficiently detects earth leakages that can cause heat buildup, preventing fires without nuisance trips. However, for direct human shock protection, consider an RCCB with a lower milliamp rating.
