ABB DS201-C20/0.03 Specifications, Features & Compatibility Guide

The 30mA sensitivity is the industry standard for life safety, as it trips in ≤40ms at 5x rated residual current to prevent cardiac arrest. A 6kA breaking capacity provides a high safety margin for residential final circuits where prospective fault currents are usually low. The 1P+N configuration with a switched neutral ensures the entire circuit is isolated during a fault, preventing potential neutral-to-earth voltage hazards.
