Input accepts 120 VAC (85 to 132 V) or 230 VAC (170 to 264 V) at 47 to 63 Hz — covers global line voltages without a tap change. The ATEX II 3G Ex nA nC IIC T4 Gc and IECEx Ex nA nC IIC T4 Gc ratings mean it is certified for use in Zone 2 gas hazardous areas (non-sparking, non-incendive) with T4 temperature class (≤135 °C surface). The cULus Class I, Div. 2 approval (File E330455) extends that to North American Division 2 locations. Galvanic isolation with safety extra-low output voltage ensures the 24 VDC side is touch-safe and isolated from the mains — critical for protecting downstream PLC I/O and field sensors. ## Mounting and wiring checklist Fastens onto the S7-300 DIN rail (standard 35 mm profile). Clearance: 40 mm top and bottom, 0 mm left and right — no side gap needed, but plan for airflow above and below. Output terminals: L+, M — two screw terminals each for the same wire range. Strip length and torque per standard practice. Recommended upstream protection: a 3 A characteristic C miniature circuit breaker in the feeder. Operating temperature range 0 to 60 °C with natural convection — no forced cooling required within that range. Storage and transport range -40 to +85 °C. CE marked. cULus-Listed to UL 508 and CSA C22.2 No. 142 (File E143289). EAC approved. FM registered for Class I, Div. 2, Groups A, B, C, D, T4. MTBF at 40 °C: 2,320,078 hours — reflects a robust design for continuous industrial operation. Maximum I²t value: 1 A²·s — relevant for fuse coordination and inrush current assessment.","metaTitle":"Siemens 6ES7307-1BA01-0AA0 SITOP Power Supply, 2 A, ATEX, UL","metaDescription":"Siemens 6ES7307-1BA01-0AA0 SITOP power supply, 2 A rated, 120/230 VAC input.
