The Siemens 5SY5101-6CC12 is a miniature circuit breaker (MCB) from the 5SY5 series, specified as a 1-pole unit with a B1 tripping characteristic, rated for 220V DC and a breaking capacity of 10kA.
Deployment context
As a DIN-rail mounted MCB, the 5SY5101-6CC12 integrates into standard panel enclosures for DC branch circuit protection. The 220V DC rating suits it for photovoltaic arrays, DC bus distribution, or battery-backed control circuits where a B-curve (short magnetic trip at 3-5x rated current) is specified.
