It is rated 10 A with a 30 mA residual-current trip, Type AC (sensitive to sinusoidal AC fault currents), and a C tripping characteristic — meaning it tolerates short inrush peaks typical of motor or capacitive loads before the thermal-magnetic mechanism clears a sustained overload or short circuit. The operating voltage is 230/240 V AC, 50/60 Hz, with an insulation voltage (Ui) of 264 V and a rated surge voltage resistance of 4 000 V — overvoltage category III, pollution degree 2, which covers fixed-installation distribution boards in buildings and light industrial environments. ## Mounting and integration into a panel Depth is 77 mm, installation depth 70 mm, height 90 mm. The supply cord can enter from either top or bottom, which simplifies busbar routing in a crowded enclosure. The 30 mA residual sensitivity (Type AC) is the standard for general-purpose socket-outlet protection in residential and commercial final circuits per IEC 60364. It detects sinusoidal AC earth faults only — not pulsating DC or smooth DC faults. If the downstream load includes rectifiers, variable-speed drives, or LED drivers that can generate DC fault components, a Type A or Type F RCBO would be needed instead. The C characteristic (10× to 15× In magnetic trip) means it will not nuisance-trip on the inrush of a small motor or a bank of capacitors, but it will still clear a hard short within the 6 kA rating.","metaTitle":"Siemens 5SU9356-1CN10 SENTRON RCBO, 10 A, 30 mA, Type AC, C-","metaDescription":"Siemens 5SU9356-1CN10 SENTRON RCBO, 1P+N, 10 A, 30 mA residual, Type AC, C characteristic, 6 kA per EN 60898 & IEC 60947-2.

They share the same 2-MW DIN-rail footprint (36 mm width, 77 mm depth), so the mechanical fit is identical, but the wiring differs: the RCBO requires a neutral connection through the device for the residual-current coil, whereas the MCB does not. A panel wired for the MCB cannot simply swap in the RCBO without adding the neutral conductor through the device."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU9356-1CN10","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SU9356-1CN10 when reusing this data.
