Type A detection covers pulsating DC and AC residual currents — the common fault shape from rectified loads like switched-mode power supplies and variable-speed drives in a panel. The 4.5 kA Icn is the short-circuit breaking capacity at the rated voltage; for installations with higher prospective fault current upstream, verify the SCCR at the panel level. ## Deployment context The 5SU9353-7CR63 snaps onto DIN rail in a distribution board or sub-distribution panel. The 1P+N form factor occupies a single module width, so it fits standard enclosure fill patterns without crowding adjacent breakers.","metaTitle":"Siemens 5SU9353-7CR63 RCBO 63A 30mA Type A C-Char, 4.5kA","metaDescription":"Siemens 5SU9353-7CR63 RCBO, 1P+N, 63 A, 30 mA Type A residual current, C-characteristic, 4.5 kA breaking capacity at 230 V AC.
