It combines a C-curve MCB with a Type A residual current device tripping at 300 mA, all in a single 3-module-wide unit. ## Installation and wiring Terminals accept solid or stranded conductors from 0.75 mm² up to 35 mm², with a tightening torque of 2.5 to 3 N·m on the screw terminals. The supply cord can enter from either top or bottom, and the neutral conductor is switched internally. For a BOM line requiring this exact order code, the 63 A rating, 50 kA breaking capacity, and Type A 300 mA residual protection define the fit — verify the tripping characteristic (C-curve) and pole configuration (2P) match your panel design before specifying.","metaTitle":"Siemens 5SU1622-7KC63 SENTRON RCBO, 63 A, 50 kA, Type A, 300","metaDescription":"Siemens SENTRON 5SU1622-7KC63 RCBO, 2-pole, 63 A, 50 kA breaking capacity per EN 60898, Type A, 300 mA residual current, C-curve.
