It mounts directly onto the S7 rail, occupying a 40 mm top clearance and 40 mm bottom clearance with zero side clearance left and right — a tight footprint for crowded DIN-rail enclosures. This unit carries ATEX (EX) II 3G Ex nA nC IIC T3 Gc and IECEx Ex nA nC IIC T3 Gc certification, meaning it is approved for installation in Zone 2 gas atmospheres with IIC gas group and T3 temperature class. ## Key Electrical Characteristics for Panel Integration Galvanic isolation provides safety extra-low output voltage (SELV) per EN 60950-1 and EN 50178, so the 5 A DC output can feed control circuits without additional isolation barriers. The recommended upstream protection is a miniature circuit breaker from 6 A, characteristic C. Maximum I²t is 1.2 A²·s, which governs fuse and breaker coordination for selectivity studies. Off-state leakage is specified at a maximum of 3.5 mA, typically 0.5 mA — relevant when sizing residual-current devices on the primary side. Operating temperature range is 0 to 60 °C with natural convection (no fan required), and storage/transport range is -40 to +85 °C. MTBF at 40 °C is 2,480,589 hours, reflecting a robust design for continuous industrial duty. ## Deployment Context — Where This Power Supply Goes This SITOP unit is sized for a S7-300 PLC rack or similar 24 VDC control load drawing up to 5 A. The S7 rail mounting and IP20 protection class mean it lives inside a sealed enclosure — typically a panel with a gland plate for cable entry. The ATEX and Class I Div. 2 approvals make it a candidate for Zone 2/Div. 2 installations in chemical processing, oil and gas skids, paint booths, or pharmaceutical lines where flammable gases may occasionally be present.","metaTitle":"Siemens 6ES7307-1EA01-0AA0 SITOP Power Supply, 5 A, ATEX","metaDescription":"Siemens 6ES7307-1EA01-0AA0 SITOP power supply, 5 A rated output, 120/230 VAC input.
