Rated at 20 A with a D-characteristic trip curve and type A residual current sensing, it breaks fault currents up to 6 kA. The D curve means it tolerates high inrush currents — typically found on motor or transformer loads — without nuisance tripping, while the type A sensing catches pulsating DC residual currents that standard AC types miss.","metaTitle":"Siemens 5SU9356-8CN20 RCBO 1+N 6 kA D char. 20 A","metaDescription":"Siemens 5SU9356-8CN20 RCBO, 1+N poles, 6 kA breaking capacity, D characteristic, type A, 20 A.
