The IP20 rating applies with connected conductors — the terminals are finger-safe but the unit is not sealed against moisture; it belongs inside a railway-rated enclosure.","metaTitle":"Siemens SENTRON 5SY5225-6CC12 MCB, 2P B25, 440 VDC, 10 kA","metaDescription":"Siemens SENTRON 5SY5225-6CC12 miniature circuit breaker, 2-pole, B-curve, 25 A, 440 VDC, 10 kA, IP20.
