Rated 6 A at 30 °C with a Type C tripping characteristic (5–10× In magnetic release), it handles moderate inrush loads like small motors, lighting banks, and control transformers on 230/240 V AC 50 Hz supplies. ## Dimensions and mounting — panel fit check The 5SU1356-1KK06 occupies 2 modular width units (36 mm wide) on a DIN rail, with a depth of 77 mm and height of 90 mm. Installation depth is 70 mm. Mounting position is any orientation. Supply can enter from either top or bottom. ## Thermal derating — what 6 A means at panel ambient At 40 °C it derates to 5.7 A, at 50 °C to 5.4 A, and at 60 °C to 5.1 A. If your panel runs warm — common in crowded enclosures — size the circuit for the derated figure at expected ambient, not the 30 °C headline.","metaTitle":"Siemens 5SU1356-1KK06 SENTRON RCBO, 6 A, Type C, 6 kA","metaDescription":"Siemens 5SU1356-1KK06 SENTRON RCBO, 1P+N, 6 A, Type C, 6 kA (EN 60898) / 25 kA (IEC 60947-2).
