It carries a 10 kA breaking capacity per IEC 60947-2 at 880 V DC, making it suitable for protecting DC distribution panels, photovoltaic combiners, and industrial DC bus systems where the fault current can reach that level. The C-curve means the magnetic trip threshold is 5 to 10 times rated current — 20 to 40 A — so it handles moderate inrush from DC loads like contactor coils or power supplies without nuisance tripping, while still clearing short circuits fast enough for the downstream equipment. The 4-pole design switches all poles simultaneously, but note that neutral conductor switching is not provided — the breaker is intended for ungrounded DC systems where all poles are line conductors. Polarity must be observed when connecting the supply. The 5SY5404-7CC snaps onto a standard DIN rail via the quick assembly system and occupies 4 modular width units (72 mm). Halogen-free and silicon-free construction reduces corrosive off-gassing in enclosed panels. The breaker is sealable for tamper-proof applications. Degree of pollution 2 and overvoltage category II cover standard industrial environments. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz — adequate for most machine-mounted panels.","metaTitle":"Siemens 5SY5404-7CC SENTRON MCB, 4A C-Curve 4P 880VDC 10kA","metaDescription":"Siemens SENTRON 5SY5404-7CC miniature circuit breaker, 4A C-curve, 4-pole, 880VDC, 10kA IEC 60947-2.

Both are 4-pole, 4-module-width units with combined terminals. The only difference is the current rating (4 A vs 16 A) and the DC breaking capacity (10 kA vs 15 kA at 880 V DC). No rewiring is needed for the same panel cutout and busbar arrangement."},{"question":"What compliance documentation does Siemens provide for 5SY5404-7CC?","answer":"The breaker is designed per IEC 60947-2 for DC applications.
