It snaps onto standard DIN rail EN 60715 35x7.5/15 and provides a safety extra-low output voltage per EN 60950-1 and EN 50178. The 50 mm top clearance and 0 mm side clearances define its mounting envelope — it needs breathing room above, not beside. The 5 A rated current is the continuous output at nominal input and 25 °C ambient. Above 24 V output, derate 4% per volt of input rise; below 100 V or 200 V input, output drops to 80% of rated. That matters if your line voltage sags — at 90 VAC you only get about 4 A. The internal T 3.15 A fuse is not user-accessible; the feeder needs a 6 A (10 A) characteristic C (B) MCB for single-phase, or a 3RV2011-1EA10 (3.8 A setting) for two-phase at 230 V. ## Where it fits and approvals Mounts on DIN rail — no drilling. Output: +, - with two screw terminals each for the same wire range. Galvanic isolation keeps the output SELV, so downstream loads stay within low-voltage protection. Approvals stack up: cULus-Listed (UL 508, CSA C22.2 No. 107.1), cCSAus (CSA C22.2 No. 60950-1, UL 60950-1), CE, EAC, and DNV GL marine type approval. No ATEX, no IECEx, no FM — not for hazardous location use. IP20 protection means it's for dry indoor panels only.","metaTitle":"Siemens 6EP3333-8SB00-0AY0 Power Supply, 5 A, 50 mm Top Clea","metaDescription":"Siemens 6EP3333-8SB00-0AY0 power supply, 5 A rated, 50 mm top clearance, UL/CSA listed, CE/EAC, active lifecycle.
