The Siemens 6EP1332-2BA00 is a SITOP PSU100M power supply rated for 3.7 A continuous output. It accepts dual AC input ranges — 93…132 V (120 V nominal) and 187…264 V (230 V nominal) at 50/60 Hz — so it lands on either a 120 V or 230 V line without rewiring. That dual-range input is the critical path for a panel build: set the wire jumper on the terminal block to match the incoming supply before energizing. Output is SELV per EN 60950-1, galvanically isolated from the input. The internal fuse is rated T 3.15 A/250 V (not user-accessible). For the feeder, Siemens recommends a 6 A miniature circuit breaker, characteristic C.
Snaps onto DIN rail EN 60715 35×7.5/15. Ambient operating range is 0…60 °C with natural convection; no forced air required. Storage and transport range is -40…+85 °C. Dimensions: top and bottom clearance is 50 mm each; left and right clearance is 0 mm — the unit can be mounted flush side-to-side with adjacent devices. That matters when you're packing modules into a tight DIN rail row.
Not NEC Class 2. If your design requires Class 2 power, this unit does not meet that marking.
The 3.7 A rating at 120/230 VAC is the headline spec that confirms fit for a BOM line calling for a 3.7 A SELV supply. The dual input range and DIN-rail footprint mean it drops into a standard control panel without panel modifications.
