Output current is rated 0 … 3 A across the operating range, derated 2 %/K above +55 °C up to the +70 °C ceiling — meaning the headline 3 A only holds while the cabinet air stays below 55 °C; in a sealed enclosure with summer ambient, the continuous figure drops before the electronics do (cite: cite:). Input accepts 85 … 264 V AC at 47 … 63 Hz or 110 … 300 V DC, so the same unit rides a 120 V control transformer, a 230 V European rail, or a 220 V DC battery-backed plant bus without re-spec (cite: cite: cite: cite: cite:). The wide AC window makes it usable across the single-phase voltages found in most switchrooms and MCC lineups without a step-down transformer ahead of it. ## What the agency marks buy you at the tender desk ATEX, IECEx, FM, and UL hazloc are all absent from the file, so any Ex-area application needs a different SITOP line (cite: cite: cite: cite:). Output is safety extra-low voltage per EN 60950-1 and EN 50178, with internal fusing and an I²t ceiling of 0.8 A²·s — i.e. the inrush profile is bounded enough that a 6 A B-curve or 2 A C-curve MCB on the feeder is the upstream protection Siemens publishes for (cite: cite: cite: cite:). ## Mounting, clearance, and panel-side wiring Snaps onto DIN rail EN 60715 35×7.5/15 and may be mounted in any orientation — the published clearances are 20 mm top and bottom with 0 mm left and right, so the unit sits cleanly between neighbours in a high-density cabinet as long as the airflow path above and below stays open (cite: cite: cite: cite: cite:). That zero side-clearance figure is the panel-space win on retrofit jobs where every DIN slot is already spoken for. IP20 housing — finger-safe at the terminals but not sealed, so it belongs inside an enclosure, not on the machine skin (cite:). ## Reliability envelope and lifecycle read MTBF at 40 °C is published as 2,931,709 h — on the order of three centuries per unit, which is the typical Siemens reliability statement for this class and is the right figure to quote into a tender durability section (cite:). Operating temperature is −25 … +70 °C with natural convection, storage −40 … +85 °C, transport −40 … +85 °C — the unit tolerates a warehouse shelf across a wide climate band before it ever sees a panel (cite: cite: cite:). Availability here runs through independent distribution against an RFQ — quote-level confirmation, with pricing and lead time validated against the BOM line at the time the RFQ is raised, not at order code lookup.","metaTitle":"Siemens 6EP3310-6SB00-0AY0 DIN Rail PSU, 24 V / 3 A","metaDescription":"Siemens 6EP3310-6SB00-0AY0 SITOP-style DIN rail power supply, 3 A output, 100–240 V AC / 110–300 V DC input, cULus + cURus NEC Class 2.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DIN Rail Power Supplies"],"specifications":{"Top":"20 mm","ATEX":"No","Left":"0 mm","IECEx":"No","Right":"0 mm","at DC":"110 ... 300 V","title":"6EP3310-6SB00-0AY0","Bottom":"20 mm","DNV GL":"Yes","Maximum":"3.8 A","Typical":"3.8 A","At Input":"L, N: 1 screw terminal each for 0.5 ... 2.5 mm2 single-core/finely stranded","At Output":"+, -: 1 screw terminal each for 0.5 ... 2.5 mm²","CE marking":"Yes","NEC Class 2":"Yes","Rated Range":"0 ... 3 A; +55 ... +70 °C: Derating 2%/K","Rated Value":"3 A","UL approval":"Yes; cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259; cURus-Recognized (UL 60950, CSA C22.2 No. 60950), File E151273, NEC class 2 (acc. to UL 1310)","description":"LOGO!Power 5 V / 3 A stabilized power supply input: 100-240 V AC output: 5 V DC / 3 A *Ex approval no longer available*","CSA approval":"Yes; cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259; cURus-Recognized (UL 60950, CSA C22.2 No. 60950), File E151273, NEC class 2 (acc. to UL 1310)","EAC approval":"Yes","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","In The Feeder":"Recommended miniature circuit breaker: from 6 A characteristic B or from 2 A characteristic C","Initial Value":"85 V","During Storage":"-40 ... +85 °C","Line Frequency":"47 ... 63 Hz","MTBF at 40 °C":"2 931 709 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, direct mounting in different mounting positions","Full-Scale Value":"264 V","I2t value maximum":"0.8 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","Maximum Rated Value":"240 V","Minimum Rated Value":"100 V","protection class IP":"IP20","Fuse Protection Type":"internal","Bridging Of Equipment":"Yes","Efficiency In Percent":"76 %","Shipbuilding Approval":"ABS, BV, DNV GL, LRS","Depth Of The Enclosure":"53 mm","Response Delay Maximum":"0.5 s","Width Of The Enclosure":"36 mm","Height Of The Enclosure":"90 mm","Voltage Curve At Output":"Controlled, isolated DC voltage","For Emitted Interference":"EN 55022 Class B","Nippon Kaiji Kyokai (NK)":"No","Adjustable Output Voltage":"4.6 ... 5.4 V","For Interference Immunity":"EN 61000-6-2","Load Step 10 To 90% Typical":"1 ms","Load Step 90 To 10% Typical":"1 ms","cCSAus, Class 1, Division 2":"No","at rated input voltage 120 V":"0.36 A","at rated input voltage 230 V":"0.22 A","Supplied Active Power Typical":"15 W","Type Of Electrical Connection":"screw-type terminals","at output 1 at DC rated value":"5 V","Type Of Output Voltage Setting":"via potentiometer","Overvoltage Overload Capability":"300 V AC for 1 s","Design Of Input Wide Range Input":"Yes","During NO-Load Operation Maximum":"0.3 W","Type Of The Power Supply Network":"1-phase AC or DC","output voltage at DC rated value":"5 V","Lloyds Register of Shipping (LRS)":"Yes","Design Of Short-Circuit Protection":"Constant current characteristic","Measuring Point For Output Current":"50 mV =^ 3 A","On Slow Fluctuation Of Ohm Loading":"0.1 %","Operating Resource Protection Class":"Class II (without protective conductor)","Design Of The Overvoltage Protection":"Yes, according to EN 60950-1","Display Version For Normal Operation":"Green LED for output voltage OK","On Slow Fluctuation Of Input Voltage":"0.1 %","French marine classification society (BV)":"Yes","Relative Overall Tolerance Of The Voltage":"3 %","Operating Condition Of The Mains Buffering":"at Vin = 187 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.
