Product Overview
The ABB FW202 is a 40A, 2-pole (2P) Residual Current Circuit Breaker (RCCB) specifically engineered for residential main incomer applications. This Type AC device operates within a 180–264V range to provide dedicated fire protection by monitoring for a 300mA residual current threshold. Manufactured in Italy, it is a non-overload protected device that must be paired with a backup MCB to ensure complete circuit safety.

Engineering Analysis
Selecting a 300mA sensitivity is vital for fire prevention at the main incomer where lower sensitivities might cause nuisance tripping from cumulative leakage across multiple sub-circuits. The 10kA conditional short circuit rating ensures the device maintains integrity during high-fault events, while the 4kV impulse withstand voltage protects against atmospheric surges. Its 2P configuration with solid neutral is essential for safely isolating residential 230V systems during a trip event.
