It accepts dual-range AC input — 120 V (93–132 V) or 230 V (187–264 V) — selectable via a front-panel switch, and handles line frequencies from 47 to 63 Hz. The output is rated continuously at 5 A over 0–60 °C with natural convection; above 45 °C, derate at 2%/K. This unit snaps onto a standard DIN rail (EN 60715 35×7.5/15) and is IP20 rated, so it belongs inside a control cabinet — not in a washdown or outdoor location. The output terminals accept 0.5–2.5 mm² stranded or solid wire; input terminals are similarly sized, with L, N, and PE each on a dedicated screw clamp. ## Installation notes Mounting requires 50 mm clearance above and below the unit for convection airflow; left and right sides can be flush (0 mm clearance). The internal fuse is a T 3.15 A/250 V (not user-accessible). Siemens recommends a 6 A characteristic C miniature circuit breaker in the feeder. Off-state leakage is typically 0.4 mA, maximum 3.5 mA — negligible for most control circuits, but worth noting if you're feeding sensitive electronics that share a residual-current device.","metaTitle":"Siemens 6EP1333-1LB00 Power Supply, 5 A, 120/230 V AC","metaDescription":"Siemens 6EP1333-1LB00 power supply, 5 A rated, 120/230 V AC input, SELV output, UL/CSA listed, IP20, DIN rail mount.
