DC-rated MCB for 63 A, C-curve, 2-pole — 5SY5263-7CC
The Siemens SENTRON 5SY5263-7CC is a 2-pole miniature circuit breaker rated for 440 V DC with a 10 kA breaking capacity per IEC 60947-2, tripping characteristic C, and a 63 A current rating. The C-curve (5–10× In) suits moderate inrush loads like contactor coils, solenoid valves, and small DC motors — common in machine-tool and conveyor controls. The 2-pole design switches both lines, and polarity must be observed when connecting the supply.
