The Siemens 5SY5115-7CC12 is a 1-pole miniature circuit breaker from the 5SY5 series, rated at 1.6 A with a C-trip curve.
DC rating and deployment
The 220 V DC rating makes this MCB suitable for DC distribution panels, battery banks, UPS output circuits, or solar combiner boxes where the string voltage lands near 220 VDC. The 10 kA interrupting rating at that voltage means it handles the available fault current typical in industrial battery or rectifier-fed DC bus systems. Snap onto standard DIN rail inside an enclosure — no special adapters needed.
