Rated for a maximum DC operating voltage of 250 V, this breaker covers the common 220 V DC bus found in many industrial control systems. The 10 kA interrupting rating at 220 V DC gives sufficient fault-clearing capacity for most panel-level DC distribution. The degree of pollution 3 rating means it's suitable for environments with conductive pollution — typical inside a non-sealed industrial cabinet. ## Environmental and compliance profile Operating temperature range spans -40 °C to 75 °C, with humidity derating: max 95% RH up to 55 °C, declining to 35% at 75 °C. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz — sufficient for installation on machinery subject to moderate vibration without nuisance tripping. The part accepts supplementary devices (product extension installable supplementary devices: Yes), allowing add-on accessories like shunt trips or auxiliary contacts without replacing the breaker.","metaTitle":"Siemens 5SY5104-7CC SENTRON MCB, 1P C 4A, 10kA DC","metaDescription":"Siemens 5SY5104-7CC SENTRON miniature circuit breaker, 1-pole, C-curve, 4 A, 10 kA DC at 220 V.
