It is designed as an add-on RCD unit for the 5SY miniature circuit breaker line, fitting into the same DIN-rail mounting scheme at 2 modular width units (36 mm). Type AC detection means it responds to sinusoidal AC residual currents — the standard choice for general-purpose socket-outlet and lighting circuits where no rectified or pulsed DC fault currents are expected. The 300 mA rating is typical for fire-protection or submain protection, not for personal shock protection (which requires ≤30 mA). ## Lifecycle and Sourcing The 5SM2622-0 carries an Active lifecycle status, so it remains in Siemens' current production portfolio. No end-of-life notification or last-time-buy window is in effect. For volume or scheduled BOM requirements, the part is quoted to order against an RFQ through independent distribution channels; availability and current pricing are confirmed at quote time. ## Panel Integration and Environment Mounts on standard DIN rail (fastening method REG) in any orientation, with a 70 mm installation depth that matches the 5SY MCB footprint. The 2-MW width (36 mm) occupies two adjacent 18 mm slots. Rated for overvoltage category III and pollution degree 2, so it is suited for distribution boards and sub-distribution panels in residential or commercial infrastructure. IP20 with connected conductors — enclosed panel required; not for washdown or outdoor exposure. Operating temperature range is -5 °C to 45 °C, with storage from -40 °C to 75 °C. The mechanical service life is rated at 10,000 operating cycles typical. Power dissipation per pole at rated current in hot state is 1.9 W — factor into enclosure thermal calculations when grouping multiple units.","metaTitle":"Siemens 5SM2622-0 SENTRON RCD Unit, 2-Pole, 40 A, 300 mA, 23","metaDescription":"Siemens 5SM2622-0 SENTRON RCD unit, 2-pole, type AC, rated 40 A / 300 mA / 230 V AC.

The 5SL4363-7 is a standalone 3-pole miniature circuit breaker (C-curve, 63 A, 400 V) — a different device class. They share the SENTRON brand and DIN-rail mounting but are not functionally interchangeable; the 5SM2622-0 provides residual current protection while the 5SL4363-7 provides overcurrent protection only."},{"question":"What compliance documentation is available for 5SM2622-0?","answer":"As a Siemens SENTRON product, the 5SM2622-0 is designed to meet applicable IEC/EN standards (IEC 61008 for RCCBs).

The part carries an overvoltage category III rating and pollution degree 2 per IEC 60947."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SM2622-0","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/5SM2622-0 when reusing this data.
