ABB DS301C-C20/0.03 Specifications, Features & Compatibility Guide

The 30mA sensitivity is critical for life safety as it ensures a trip time of ≤40ms at 5 times the rated residual current. With a 6kA breaking capacity and 10kA conditional short-circuit rating, this Italian-made device manages high-energy faults common in urban residential grids. Its 1P+N configuration is essential for modern neutral protection, ensuring the entire circuit is safely disconnected during a leakage event.
