The 440 V DC rating covers common DC bus voltages in drives and solar combiner boxes — it will hold off arc extinction at that voltage, which is the critical parameter for DC breakers. The C8 curve (8 A nominal, magnetic trip at 5–10× In) is sized for moderate inrush loads: think a bank of small DC contactors or a PLC power supply, not a large capacitor bank.","metaTitle":"Siemens 5SY5208-7CC12 MCB, 440V DC, 10kA, 2P C8","metaDescription":"Siemens 5SY5208-7CC12 MCB, 440V DC, 10kA, 2-pole, C8 curve.
