The Siemens 6EP7133-6AB00-0BN0 is a SITOP PSU8200 power supply rated for 6 A output, with a continuous 5 A up to +60 °C and derating above that. It accepts dual AC input ranges — 85…132 V or 170…264 V — and automatically selects the range. The unit snaps onto a 35 mm DIN rail per EN 60715, with a 50 mm width that fits standard panel cutouts. Output is safety extra-low voltage (SELV) per EN 60950-1 and EN 50178, so it can supply control circuits without additional isolation. The 50 mm height and 0 mm left/right clearance requirements mean it packs tightly into a crowded cabinet — no side breathing gaps needed.
Certifications and approvals
This unit carries ATEX II 3G Ex ec nC IIC T3 Gc and IECEx Ex ec nC IIC T3 Gc, making it suitable for Zone 2 gas environments. UL and CSA listings cover UL 61010-2-201, CSA C22.2 No. 142, plus ITE safety standards (UL 60950-1, CSA C22.2 No. 60950-1). CE, UKCA, EAC, and C-Tick marks are also present. Marine approval from DNV GL is on file.
Mounting and wiring
Input terminals: L, N, PE each accept one PushIn connector for 0.2…2.5 mm² solid or finely stranded wire. Output side has two PushIn terminals per polarity (+ and -) for the same wire range. The recommended upstream protective device is a B/C 6 A or 3 A miniature circuit breaker. Operating temperature range is -30…+70 °C with natural convection; storage and transport range is -40…+85 °C. The MTBF at 40 °C is 1 598 441 hours. I²t value is 3.15 A²·s, useful for fuse coordination.
