The 32 A rating handles the continuous load; the D curve avoids nuisance tripping on startup. Type A residual current detection covers pulsating DC fault currents (rectified waveforms from electronics), not just pure AC — so it fits circuits with VFDs, UPS, or switched-mode power supplies downstream. The 100 mA sensitivity is a delayed or selective earth-fault threshold, often chosen for fire protection or to coordinate with downstream 30 mA RCDs.","metaTitle":"Siemens 5SU1424-8RC32 RCBO, 32 A, 2-pole, D curve, Type A, 1","metaDescription":"Siemens 5SU1424-8RC32 RCBO: 32 A, 2-pole, 4-module, D characteristic, Type A, 100 mA residual current.
