Product details

The Siemens 6EP1333-4BA00 is a 24 V DC power supply from the SITOP PSU8200 series, rated for 8 A continuous output. It accepts dual-range AC input — 85–132 V or 170–264 V — at 45–65 Hz, with automatic range selection. The unit is designed for mounting directly on an S7-1500 rail, saving panel space. This supply carries ATEX II 3G Ex nA nC IIC T3 Gc and IECEx Ex nA nC IIC T3 Gc certifications, plus cULus hazloc approval for Class I, Div. 2, Groups A, B, C, D, T3 (File E330455). That means it is qualified for installation in Zone 2 gas environments and Division 2 locations — a common requirement for chemical, oil & gas, and pharmaceutical lines. Output terminals are spring-loaded (L+, M) accepting 0.5–2.5 mm²; input uses screw terminals for L, N, PE. The recommended upstream protection is a 16 A B-curve or 10 A C-curve MCB. Galvanic isolation provides SELV output per EN 60950-1, EN 50178, and EN 61131-2.

The unit requires 40 mm clearance above and below (top and bottom) for natural convection cooling. No side clearance is needed — left and right are 0 mm. This fits a standard 80 mm tall DIN-rail slot with the supply centered. Operating temperature range is 0–60 °C with natural convection; storage and transport range is -40 to +85 °C.

Compliance & Approvals

Full approval set: CE, cULus (UL 508, CSA C22.2 No. 142, File E143289), EAC, FM (Class I, Div. 2, Group ABCD, T4), ATEX, IECEx, and DNV GL. The ATEX and IECEx certifications cover gas group IIC, temperature class T3. The cULus hazloc listing (File E330455) covers Class I, Div. 2, Groups A, B, C, D, T3. Protection class is IP20.
