It carries a supply voltage rating of 400 V AC at 50 Hz, and its breaking capacity is dual-rated: 6 kA according to EN 60898 and 30 kA according to IEC 60947-2. The 2-pole configuration with a 400 V AC rated voltage means it protects two phase conductors in a single-phase or split-phase circuit, or one phase plus neutral in a 230/400 V system. The 6 kA EN 60898 rating covers the standard domestic/small commercial installation; the 30 kA IEC 60947-2 rating applies when the breaker is used in an industrial distribution board where the fault level is higher — the actual rating depends on the standard the local code requires. Mechanical service life of 10 000 operating cycles typical for this class of MCB. ## Wiring and terminal capacity Accepts solid conductors up to 35 mm², which covers standard panel wiring for a 2-pole MCB at this voltage class. The 70 mm installation depth matches the standard SENTRON enclosure depth; no special deep box needed.","metaTitle":"Siemens 5SN6201-8CP SENTRON MCB, 2-Pole, 400V AC, 6kA / 30kA","metaDescription":"Siemens 5SN6201-8CP SENTRON 2-pole MCB rated 400V AC at 50 Hz.

The key difference is the 5SU9354-7KK16 is an RCBO (RCD + MCB combined) with a 230/240 V AC rating, while the 5SN6201-8CP is a plain MCB rated 400 V AC — they are not electrically interchangeable in function."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SN6201-8CP","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/5SN6201-8CP when reusing this data.
