ABB FW202 63A-30mA Specifications, Features & Compatibility Guide

The 30mA sensitivity rating is calibrated specifically for human safety, ensuring the circuit trips before current levels reach the threshold for cardiac arrest. Its 10kA breaking capacity allows the unit to maintain structural integrity during significant fault events when paired with a coordination-appropriate backup MCB. The 2-pole design provides solid neutral protection, which is essential for isolating the entire residential circuit during an earth fault.
