The DC side carries a 220 V rating; the AC supply can be connected as required, but DC polarity must be observed per the manufacturer's note. Touch protection is built in (IP20 with connected conductors), and the unit is sealable — useful for panel builders who need to lock settings after commissioning.","metaTitle":"Siemens 5SY5102-7KK11 SENTRON MCB, 1P C 2A, 10 kA, Railway","metaDescription":"Siemens SENTRON 5SY5102-7KK11 miniature circuit breaker, 1-pole C-curve 2 A, 10 kA breaking capacity per EN 60898.
