The 10 A figure is the full rated current across the 0–10 A range; below 110 V AC/DC the output power derates to 100 W max, so a 24 V rail pulling 10 A needs at least 110 V on the input side to hold full power. Galvanic isolation provides safety extra-low voltage (SELV) per EN 60950-1, which means the output is touch-safe and suitable for feeding control circuits, PLCs, and sensors without an additional isolation transformer. The unit snaps onto a DIN rail EN 60715 35×7.5/15 — standard panel mount, no drilling. ## Mounting and thermal derating In a 65 °C cabinet, that means 10 % derating — 108 W available instead of 120 W. Storage and transport range is –40 to +85 °C. IP20 protection — suitable for clean, dry control cabinets; not for washdown or outdoor use. The unit is ATEX and IECEx rated No, so it is not certified for explosive atmospheres. Clearance distances: top 50 mm, bottom 50 mm, left 0 mm, right 0 mm. That means zero side gap is acceptable — units can be mounted side-by-side without spacing, but 50 mm above and below must be free for convection airflow. ## Approvals and feeder protection UL/cULus-Listed under UL 508 and CSA C22.2 No. 107.1, File E197259 — accepted for North American panels. CE marked, EAC approved, C-Tick for Australia. Not CSA approved separately (covered by cULus), not DNV GL or FM registered, not NEC Class 2. Recommended feeder protection: a miniature circuit breaker 6–10 A, characteristic C. The maximum I²t value is 1 A²·s, which helps with coordination when sizing the upstream breaker. ## Connections and wiring Input terminals (, N, PE): one screw terminal each for 0.5–2.5 mm² single-core or finely stranded wire. Output terminals (+, –): two screw terminals each for the same wire range — useful for daisy-chaining to multiple loads without a separate distribution block. ## Reliability and transient response MTBF at 40 °C is 1 200 000 hours — roughly 137 years continuous. Typical response time (likely transient recovery or start-up delay) is 20 ms. Maximum leakage current is 3.5 mA, relevant for earth-leakage breaker coordination in sensitive installations.","metaTitle":"Siemens 6EP3343-0SA00-0AY0 SITOP PSU8200, 10 A / 120 W","metaDescription":"Siemens SITOP PSU8200 6EP3343-0SA00-0AY0 power supply, 10 A rated, 120 W output, 85-264 V AC/DC input, UL 508 listed.
