It accepts 85-132 V or 170-264 V AC at 47-63 Hz with automatic range selection. The 6 A rating holds up to +45 °C; derate 1.6%/K above that up to +70 °C. Input terminals (L, N, PE) are single screw clamps accepting 0.5-2.5 mm²; output terminals (+, -) give you two screw clamps per polarity for daisy-chaining or separate load feeds. ## Protection and isolation Output is safety extra-low voltage (SELV) per EN 60950-1 and EN 50178, so it's suitable for powering control circuits, PLCs, and sensors where galvanic isolation from the mains is required. An internal T 3.15 A/250 V fuse protects the primary side. Siemens recommends a 6 A characteristic C miniature circuit breaker in the feeder line — that's your selectivity starting point for the upstream protection. Carries cULus listing under UL 508 and CSA C22.2 No. 107.1 (File E197259), plus cCSAus per UL/CSA 60950-1. Also CE and EAC marked, so it's accepted across North America, the EU, and Eurasian Customs Union markets. No ATEX or IECEx rating — not certified for hazardous locations. Lifecycle status is current production.","metaTitle":"Siemens 6EP1333-2BA20 Power Supply, 6 A, DIN Rail","metaDescription":"Siemens 6EP1333-2BA20 power supply, 6 A rated output, 85-264 VAC input, DIN rail mount, UL/CSA listed, CE marked.
