For a panel that runs warm (say 45–50 °C ambient inside the enclosure), the continuous load should be sized against the derated value, not the 30 °C number. At 72 mm wide (4 modular width units) and 85 mm tall, the 5SU1346-6FP32 occupies four adjacent slots on a standard 35 mm DIN rail. Installation depth is 70 mm; the overall depth including the front face is 72 mm. Supply can enter from either the top or bottom — no mandatory orientation for line/load.","metaTitle":"Siemens 5SU1346-6FP32 SENTRON RCBO, 4P, 32 A, 6 kA, Type B","metaDescription":"Siemens 5SU1346-6FP32 SENTRON RCBO, 4-pole, 32 A rated at 30 °C, 6 kA breaking capacity per EN 60898, Type B characteristic.
