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. ## Footprint and panel fit It mounts in any position and uses the quick-assembly system for snap-on rail attachment.","metaTitle":"Siemens 5SY5263-7CC SENTRON MCB, 63A C-curve 2-pole DC 440V","metaDescription":"Siemens SENTRON 5SY5263-7CC miniature circuit breaker, 63A, C-curve, 2-pole, 440 V DC, 10 kA breaking capacity per IEC 60947-2.
