Main Features and Advantages

The 6EP1333-3BA00​ sits at the intersection of “simple enough for a panel builder, configurable enough for a system house,” and that duality is where its value lives. The wide-range input—85–132 V on the low tap, 176–550 V on the high tap—means a single MLFB covers 120 V North American singles, 230 V European singles, and two legs of a 400–500 V three-phase distribution without reordering. For EPCs that standardize a panel family across multiple continents, stocking the 6EP1333-3BA00​ instead of region-split PSUs simplifies sparing and documentation.Power Boost is the second differentiator. The 6EP1333-3BA00​ can deliver 3 × rated current (≈15 A) for 25 ms—the so-called “Power Boost” window that carries inductive inrush from contactors, solenoid valves, or motor-starter coils without tripping the PSU or forcing a larger frame size. For loads that sit at 4–5 A steady but spike on startup, this keeps the designer on a 5 A frame rather than stepping up to the 10 A sibling unnecessarily. Short-circuit behavior is jumper-selectable via switch B: constant-current clamp at ~5.5 A (amber LED, auto-recovery) versus latch-off (red LED, manual reset or remote OFF via auxiliary module 6EP1961-3BA10). Being able to pick the trip philosophy per panel—reset-happy machine builder vs. fail-safe process cabinet—is why the 6EP1333-3BA00​ survives in both machinery OEM and process-DCS contexts.Diagnostics are intentionally minimal but sufficient: green LED confirms >20.5 V DC present, amber flags an overload still in constant-current, red flags a latched fault or remote OFF. No display, no communications—by design, because adding a fieldbus head to a 5 A PSU complicates sparing and raises cost. If remote signaling or extended buffering is required, Siemens offers the 6EP1333-3BA00–compatible auxiliaries: 6EP1961-3BA00 extends mains buffer to ~3 s, 6EP1961-3BA10 adds input/output monitoring contacts and remote ON/OFF. The base 6EP1333-3BA00​ stays lean; the auxiliaries bolt on when the application demands it. Certifications round out the advantage list—SEMI F47 makes it wafer-fab friendly, cULus opens North American panels, ABS/DNV GL covers marine, and the IP20 / Class I / SELV stack satisfies both machinery (EN 60204) and process (IEC 61131 cabinet) specs.

Application Field

The 6EP1333-3BA00​ is the kind of 24 V DC 5 A supply that ends up in almost every industrial cabinet type because its input range and certifications refuse to pigeonhole it. In factory automation it powers S7-300/S7-400 PLC racks, ET 200 distributed I/O heads, HMI panels, and small servo/motor-starter clusters on 24 V side—machine builders like it because the 70 mm width preserves DIN-rail real estate and the Power Boost carries contactor inrush without derating. In process automation the 6EP1333-3BA00​ feeds Teleperm M or SPPA-T3000 auxiliary racks, remote I/O shelters, and analyzer houses where 24 V DC is the field instrument rail and upstream mains may be 230 V single-phase in one shelter and 400 V two-leg in the next; one MLFB covers both.Infrastructure and utility panels are another footprint—pump stations, water/wastewater SCADA kiosks, substation RTU cabinets, and solar balance-of-system combiner-monitoring boxes routinely specify the 6EP1333-3BA00​ because SEMI F47 and the 1300 Vₚ / 1.3 ms surge withstand match utility-grade transients better than commodity switched bricks. On the machinery OEM side, packaging lines, bottling depalletizers, conveyor merges, and CNC auxiliary cabinets use the 6EP1333-3BA00​ in stacks—one per control zone—because paralleling two units (selector A set) doubles the 24 V budget without jumping to a 10 A frame that may not fit the zone’s width allowance.Marine and offshore is the fourth niche: ABS and DNV GL approvals plus the wide input range make the 6EP1333-3BA00​ a default choice on deck-machinery controls, engine-room monitoring cabinets, and topside process skids where the supply might be 440 V 60 Hz one vessel and 230 V 50 Hz the next. For plant maintenance teams the application case is often obsolescence-driven sparing—PSU200M is mature but not discontinued, yet lead times fluctuate, so keeping two 6EP1333-3BA00​ per panel family on the shelf avoids a forced overnight expedite when a green-LED failure finally shows up after a decade of service.
