The 6EP1436-2BA10 is a SITOP PSU8200 power supply rated for 20 A continuous output at 400-500 VAC three-phase input. It delivers 91% efficiency and snaps onto standard DIN rail EN 60715 35x7.5/15 — no drilling, no bracket.
The 20 A output is the full rated current at 25 °C ambient. The I²t maximum of 0.9 A²·s tells you the energy the output can deliver into a short-duration overload — useful when sizing the upstream breaker. The feeder requires a 3-pole miniature circuit breaker 6-16 A characteristic C, or a Siemens 3RV2011-1DA10 set at 3 A (or 3RV2711-1DD10 for UL 489). That means the supply itself doesn't carry branch-circuit protection; you must provide it externally.
cULus-Listed to UL 508 and CSA C22.2 No. 107.1 (file E197259), plus cCSAus to CSA C22.2 No. 60950-1 and UL 60950-1. CE marked, EAC approved, DNV GL marine type-approved. No ATEX or IECEx rating, no UL hazardous location listing — keep it out of classified areas. Galvanic isolation provides SELV output per EN 60950-1 and EN 50178, transformer per EN 61558-2-16.
