The C characteristic (32 A) means the magnetic trip is calibrated for moderate inrush — typical for lighting, socket circuits, or small motor loads — so it holds through the start-up surge but clears fast on a hard short. The Type A residual-current detection (300 mA) covers pulsating DC fault currents from single-phase rectified loads (switched-mode supplies, LED drivers, VFDs), which a plain AC-sensitive RCD would miss. 300 mA is a fire-protection threshold, not a personnel-protection level (that would be 30 mA); it is sized for circuits where the leakage budget is higher and the priority is cable/equipment protection. ## Deployment context The 2-module width (36 mm at 18 mm per module) fits compact sub-distribution boards where space is tight. Rated for 32 A — sized for a submains or a heavy final circuit, not a lighting subcircuit.","metaTitle":"Siemens 5SU1654-7RC32 RCBO, 32 A, 2-pole, Type A 300mA","metaDescription":"Siemens 5SU1654-7RC32 RCBO, 32 A, 2-pole, C-curve, Type A 300mA residual current.
