If the panel ambient runs above 40 °C, factor the derated value into the load schedule — a 20 A circuit at 50 °C is effectively an 18.9 A circuit. Insulation voltage Ui 500 V, surge voltage resistance 4 kV. Snap-on DIN rail mount, 2 MW wide (36 mm), depth 72 mm, installation depth 70 mm. The halogen-free designation is No, so if the specification requires halogen-free materials (e.g., for rail or marine), this part does not meet it.","metaTitle":"Siemens 5SU1324-6FN20 SENTRON RCBO, 2P B 20 A 30 mA, 10 kA","metaDescription":"Siemens SENTRON RCBO 5SU1324-6FN20, 2-pole, B-curve, 20 A, 30 mA, 10 kA breaking capacity per EN 60898.
