It accepts a wide AC input: 85 to 264 V on one phase, or 176 to 550 V on two phases — so it handles everything from a shaky single-phase line to a 480 V three-phase panel without a separate transformer. Line frequency tolerance is 47 to 63 Hz, covering 50 and 60 Hz grids. The unit snaps onto a standard DIN rail per EN 60715 35x7.5/15, and its IP20 enclosure keeps fingers out but isn't sealed for washdown — fine for a clean control cabinet, not for a wet floor. The 5 A continuous rating (rated value) is what the supply can deliver indefinitely at rated input and 25 °C ambient. The I²t maximum of 1.7 A²·s tells you the thermal stress the output can handle during a short burst — useful for sizing upstream protection or estimating inrush into a capacitive load. Efficiency is 87 %, typical for this class; the rest dissipates as heat, so factor that into cabinet ventilation. Galvanic isolation is safety extra-low voltage (SELV) per EN 60950-1 and EN 50178, meaning the output is safe to touch and can power 24 V DC control circuits without additional isolation barriers. The MTBF at 40 °C is 885,740 hours — roughly 100 years — which is a reliability figure for fleet planning, not a warranty. This is a DIN-rail-mount power supply for control cabinets — think PLC racks, 24 V DC sensors, contactor coils, and analog loops. The wide input range makes it a natural fit for global machines that ship to both 230 V and 480 V regions; the dual-range input means the same part works in a 208 V panel or a 400 V line without a rewire. The recommended upstream protection is spelled out per input configuration: a 6 A (10 A) miniature circuit breaker, characteristic C (B) for single-phase, or a specific 3RV breaker for two-phase operation at 230 V or 400/500 V. That's not a suggestion — the inrush can trip a standard breaker if undersized.","metaTitle":"Siemens 6EP1333-3BA00 SITOP PSU, 5 A, 85-264/176-550 VAC","metaDescription":"Siemens 6EP1333-3BA00 SITOP power supply, 5 A rated output, wide-range AC input 85-264/176-550 V, cULus listed, IP20, DIN rail mount.
