It combines overcurrent and earth-fault protection in a single DIN-rail unit — one part number covers the branch circuit for both overload/short and leakage, saving a module slot over a separate MCB+RCCD pair. The C characteristic means the magnetic trip operates at 5 to 10 times rated current — 200 to 400 A peak — sized for motor and lighting inrush without nuisance trips on a 40 A circuit. Type A residual detects pulsating DC fault currents up to 30 mA, covering single-phase rectified loads (VFDs, switched-mode supplies) that a plain AC-sensitive RCCD would miss.","metaTitle":"Siemens 5SU1324-7RC40 RCBO, 40A 2-pole C Type A 30mA","metaDescription":"Siemens 5SU1324-7RC40 RCBO, 40 A, 2-pole, 4-module, C characteristic, Type A, 30 mA residual current.
