That means it combines a 16 A miniature circuit breaker (C-curve for motor-start and moderate inrush loads) with a 30 mA Type A residual-current device in a single 1-module-wide unit — saving a DIN-rail position versus two separate devices. Its 1-module width (approx. 18 mm) fits compact consumer units and sub-distribution boards. C-characteristic trips between 5× and 10× In (80–160 A magnetic release), so it handles the inrush of small motors, pumps, and transformers up to about 3.5 kW at 230 V without nuisance tripping. The 30 mA residual threshold provides additional shock protection for socket-outlet circuits and portable equipment.","metaTitle":"Siemens 5SU9346-7CR16 RCBO, 6 kA, 1P+N, Type A, 30 mA, C-16","metaDescription":"Siemens 5SU9346-7CR16 RCBO, 6 kA breaking capacity, 1P+N, Type A, 30 mA residual, C-characteristic, 16 A rated current, 230 V AC.
