If the panel runs hot — say 50 °C inside a sealed enclosure — the usable continuous current drops to 17.4 A. Overvoltage category III. Energy limiting class 3. Halogen-free and silicon-free construction. IP20 with distribution board installed and conductors connected. The product is classified per DIN EN 61346-2 and DIN EN 81346-2 as function F.","metaTitle":"Siemens 5SU1324-6FM20 SENTRON RCBO, 2P, 20 A, Type A, 10 kA","metaDescription":"Siemens 5SU1324-6FM20 SENTRON RCBO, 2-pole, 20 A rated, Type A fault current, 10 kA breaking capacity per EN 60898.
