The feeder requires a 3-pole miniature circuit breaker 10-16 A, characteristic C, or a Siemens 3RV2011-1DA10 (set to 3 A) or 3RV2711-1DD10 (UL 489). ## Output and derating Rated output is 24 V DC at 40 A continuous, with a 92% efficiency at full load. Above +60 °C ambient, the unit derates 3.75 %/K — at +70 °C the available current drops to roughly 25 A. The output terminals accept 0.33 to 10 mm² wire; two screw terminals per polarity (+ and -) simplify load distribution. The galvanic isolation provides safety extra-low voltage (SELV) per EN 60950-1 and EN 50178, so the output is safe to touch and suitable for supplying control circuits directly. ## Sourcing and RFQ No stock-holding claim is made; each order is quoted individually.","metaTitle":"Siemens 6EP1437-3BA10 SITOP PSU6200, 40 A","metaDescription":"Siemens 6EP1437-3BA10 SITOP PSU6200, 40 A output, 400-500 V AC input, 92% efficiency, UL 508 listed.
