It accepts a 3-phase input of 400 to 500 VAC at 47 to 63 Hz, making it a direct fit for standard European and North American industrial mains without a step-down transformer. Rated output holds at 5 A continuously; up to 6 A is permissible at ambient temperatures up to +45 °C. Above +60 °C, derate linearly at 5 % per Kelvin up to the +70 °C operating limit. This matters for panels running near the thermal ceiling — plan your load margin accordingly. Efficiency hits 89.5 % at rated load, which keeps enclosure heat rise manageable. The unit snaps onto a DIN rail EN 60715 35x7.5/15 — standard panel integration, no adapter plate needed. ## Approvals and Compliance — What the Certifications Mean Carries cULus-Listing under UL 508 and CSA C22.2 No. 107.1 (File E197259), plus cCSAus to CSA C22.2 No. 60950-1 and UL 60950-1. That means it is accepted for panel builds destined for North American sites without a separate NRTL review. Also holds CE, EAC, C-Tick, and shipbuilding approvals from ABS and DNV GL. Not rated for ATEX or IECEx hazardous locations, and not NEC Class 2. For ordinary industrial environments (dry, non-hazardous) this is the standard choice; if the line runs in a classified area, you need a different SITOP variant with the appropriate protection. ## Wiring and Integration Notes Input terminals:, L2, L3, PE — one screw terminal each, accepting 0.05 to 2.5 mm² single-core or finely stranded wire. Output terminals: + and -, two screw terminals each for 0.2 to 2.5 mm². The dual output terminals simplify daisy-chaining to downstream loads or a distribution block. The upstream feeder requires a 3-pole miniature circuit breaker, 3 to 16 A, characteristic C, or a Siemens 3RV2011-1DA10 (set to 3 A) or 3RV2711-1DD10 (UL 489 listed). This is not optional — the breaker provides the branch-circuit protection the UL listing assumes. Galvanic isolation provides safety extra-low output voltage (SELV) per EN 60950-1 and EN 50178, with a transformer built to EN 61558-2-16. The I²t let-through is 0.5 A²·s maximum, which helps with downstream fuse coordination. Optional accessories include a redundancy module, buffer module, selectivity module, and DC UPS — all from the SITOP family, all designed to share the same DIN-rail footprint and wiring scheme. This is a current-production part with an MTBF of 500,000 hours at 40 °C. The closest functional sibling in the SITOP family is the 6EP1336-3BA00, a single-phase 400-500 VAC unit with a lower output rating. The 6EP1433-2BA20 is the 3-phase version — if your panel already has 3-phase mains, this is the correct drop-in; the single-phase sibling would require a different feeder circuit and may not match the existing wiring plan.","metaTitle":"Siemens 6EP1433-2BA20 SITOP PSU8200, 5 A, 400-500 VAC input","metaDescription":"Siemens 6EP1433-2BA20 SITOP PSU8200 power supply, 5 A rated (8 A max), 400-500 VAC 3-phase input, 89.5% efficiency, UL/CSA listed, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DIN Rail Power Supplies"],"specifications":{"ATEX":"No","IECEx":"No","C-Tick":"Yes","DNV GL":"Yes","Maximum":"8 A","Typical":"6.6 A","At Input":"L1, L2, L3, PE: 1 screw terminal each for 0.05 ... 2.5 mm² single-core/finely stranded","At Output":"+, -: 2 screw terminals each for 0.2 ... 2.5 mm²","CE marking":"Yes","NEC Class 2":"No","Rated Range":"0 ... 5 A; 6 A up to +45°C; +60 ... +70 °C: Derating 5%/K","Rated Value":"5 A","UL approval":"Yes; cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259; cCSAus (CSA C22.2 No. 60950-1, UL 60950-1)","CSA approval":"Yes; cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259; cCSAus (CSA C22.2 No. 60950-1, UL 60950-1)","EAC approval":"Yes","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","In The Feeder":"Required: 3-pole connected miniature circuit breaker 3 ... 16 A characteristic C or circuit breaker 3RV2011-1DA10 (setting 3 A) or 3RV2711-1DD10 (UL 489-listed, DIVQ)","Initial Value":"340 V","During Storage":"-40 ... +85 °C","Line Frequency":"47 ... 63 Hz","MTBF at 40 °C":"500 000 h","FM registration":"No","lifecycle_stage":"current","During Operation":"-25 ... +70 °C; with natural convection","During Transport":"-40 ... +85 °C","Fastening Method":"Snaps onto DIN rail EN 60715 35x7.5/15","Full-Scale Value":"550 V","I2t value maximum":"0.5 A²·s","Other Information":"Specifications at rated input voltage and ambient temperature +25 °C (unless otherwise specified)","ULhazloc approval":"No","Galvanic Isolation":"Safety extra-low output voltage Uout acc. to EN 60950-1 and EN 50178, transformer acc. to EN 61558-2-16","Maximum Rated Value":"500 V","Minimum Rated Value":"400 V","protection class IP":"IP20","Bridging Of Equipment":"Yes","Efficiency In Percent":"89.5 %","Shipbuilding Approval":"ABS, DNV GL","Depth Of The Enclosure":"120 mm","Electrical Accessories":"redundancy module, buffer module, selectivity module, DC UPS","For Auxiliary Contacts":"13, 14 (alarm signal): 1 screw terminal each for 0.2 ... 2.5 mm²","Mechanical Accessories":"Device identification label 20 mm × 7 mm, pale turquoise 3RT1900-1SB20","Response Delay Maximum":"1.5 s","Width Of The Enclosure":"50 mm","Height Of The Enclosure":"125 mm","Voltage Curve At Output":"Controlled, isolated DC voltage","For Emitted Interference":"EN 55022 Class B","Nippon Kaiji Kyokai (NK)":"No","Type Of Signal At Output":"Relay contact (NO contact, rating 60 V DC/ 0.3 A) for \"24 V OK\"","Adjustable Output Voltage":"24 ... 28 V","For Interference Immunity":"EN 61000-6-2","Load Step 10 To 90% Typical":"4 ms","Load Step 90 To 10% Typical":"4 ms","cCSAus, Class 1, Division 2":"No","Load Step 100 To 50% Typical":"3 ms","Load Step 50 To 100% Typical":"3 ms","at rated input voltage 400 V":"0.45 A","at rated input voltage 500 V":"0.4 A","Supplied Active Power Typical":"120 W","Type Of Electrical Connection":"screw-type terminals","at output 1 at DC rated value":"24 V","For Mains Harmonics Limitation":"EN 61000-3-2","Type Of Output Voltage Setting":"via potentiometer; max. 120 W","Design Of Input Wide Range Input":"Yes","Type Of The Power Supply Network":"3-phase AC","output voltage at DC rated value":"24 V","Lloyds Register of Shipping (LRS)":"No","Design Of Short-Circuit Protection":"Constant current characteristic","On Slow Fluctuation Of Ohm Loading":"0.1 %","Operating Resource Protection Class":"Class I","Design Of The Overvoltage Protection":"protection against overvoltage in case of internal fault Vout < 35 V","Display Version For Normal Operation":"Green LED for 24 V OK","On Slow Fluctuation Of Input Voltage":"0.1 %","French marine classification society (BV)":"No","Relative Overall Tolerance Of The Voltage":"3 %","Operating Condition Of The Mains Buffering":"at Vin = 400 V","Product Function Output Voltage Adjustable":"Yes","Property Of The Output Short-Circuit Proof":"Yes","Galvanic Isolation Between Input And Output":"Yes","American Bureau of Shipping Europe Ltd.
