It accepts single-phase AC input at 120 V or 230 V nominal (85–132 V / 170–264 V ranges) at 50/60 Hz. The output is safety extra-low voltage (SELV) per EN 60950-1 and EN 50178, so it's suitable for powering PLCs, I/O racks, sensors, and other control-circuit loads in an industrial panel. Mounting snaps onto standard DIN rail EN 60715 (35×7.5/15). Input and output connections use screw terminals accepting 0.5–2.5 mm² wire. The 10 A continuous rating is the headline figure, but the rated range of 0–12 A up to +45 °C gives you headroom for short-term peaks or loads that don't exceed the thermal limit. Above +45 °C you need to derate; the unit operates up to +60 °C with natural convection. The internal fuse is a T 6.3 A / 250 V (non-accessible), so external branch protection is required — Siemens recommends a 10 A C-curve MCB in the feeder. The I²t value of 3.3 A²·s tells you the energy let-through during a fault — useful for coordinating with upstream breakers. MTBF at 40 °C is 1,460,803 hours, which translates to a long service life in a climate-controlled panel. This unit carries CE marking, UL/cULus listing (UL 508, CSA C22.2 No. 107.1, File E197259), cCSAus (CSA C22.2 No. 60950-1, UL 60950-1, UL 1604), and EAC approval. It is not ATEX or IECEx rated, so it is not certified for explosive atmospheres. DNV GL marine approval is present, which covers shipboard and offshore installations. ## Sourcing and fit considerations The 6EP1334-2AA01 is a standard SITOP PSU100M unit. If your BOM originally called for the higher-current sibling 6EP1336-3BA00 (20 A), this 10 A version will not drop in without rewiring — the output terminals are the same, but the load must be within the 10 A continuous limit. For a panel designed around the 20 A unit, you would need to verify the total load current and possibly upsize the supply. Conversely, if your panel was specified for this 10 A unit, the 20 A version is physically larger and may not fit the same DIN-rail footprint without panel modifications.","metaTitle":"Siemens 6EP1334-2AA01 SITOP PSU100M 24V 10A, 0-12A rated","metaDescription":"Siemens 6EP1334-2AA01 SITOP PSU100M power supply, 24V 10A, 0-12A rated range, UL/CSA listed, DIN rail mount, active production.
