The 100 mA Type AC residual current detects sinusoidal AC earth faults; it is standard for general-purpose circuits not serving sensitive electronics or DC components. The dual breaking capacity (10 kA EN 60898 / 15 kA IEC 60947-2) means the device can safely interrupt fault currents up to 15 kA at the panel level, which is typical for main or sub-main distribution in commercial and light industrial installations. The 7-module width (126 mm) means it occupies seven 18 mm DIN-rail positions — plan for this in the distribution board layout.","metaTitle":"Siemens 5SU1444-1RC63 SENTRON RCBO, 63 A, 4P, C-Char, 100 mA","metaDescription":"Siemens SENTRON 5SU1444-1RC63 RCBO, 63 A, 4-pole, C characteristic, Type AC, 100 mA residual current.
