The Siemens SENTRON 5SU1622-7KC63 is a 2-pole RCBO (residual current circuit breaker with overcurrent protection) rated 63 A at 400 V AC, 50 Hz. 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.
