At 40 °C it derates to 19.5 A, at 50 °C to 18.9 A, and at 60 °C to 18.4 A — so if the panel runs hot, size the upstream protection for the derated value, not the 30 °C figure. ## Residual current and selectivity The 30 mA trip threshold is the standard for personal protection against electric shock. The super resistant K design indicates enhanced immunity to nuisance tripping from surge currents and voltage transients — useful on lines with switching power supplies or motor drives. Depth is 72 mm, installation depth 70 mm — confirm the gland plate clearance if the board is shallow.","metaTitle":"Siemens 5SU1324-6FR20 SENTRON RCBO, 2-pole, B-curve, 20 A, 3","metaDescription":"Siemens 5SU1324-6FR20 SENTRON RCBO, 2-pole, B-curve, 20 A, 30 mA residual current, 10 kA breaking capacity.
