Legrand DX3 RCBO DP 32A 30mA Specifications, Features & Compatibility Guide

The 30mA sensitivity is essential for human life protection as it trips the circuit within ≤40ms at 5x Idn, well before muscle contraction occurs. The 10kA breaking capacity is specifically chosen for residential incomers to withstand high prospective fault currents near the distribution transformer. With 2 modules (36mm) width and switched neutral protection, it ensures total circuit isolation and high selectivity in modern home wiring layouts.
