Single-pole width saves rail space compared to a two-pole DC breaker when you only need to switch the positive leg. The 5SY5 series uses the same tunnel terminals as the rest of the 5SY line — wire it with the same ferruled conductors you'd use for the AC branch breakers alongside it.","metaTitle":"Siemens 5SY5103-6CC12 MCB, 1P B3, 220V DC, 10kA","metaDescription":"Siemens 5SY5103-6CC12 miniature circuit breaker, 1-pole B-curve, 3A, rated 220V DC with 10kA breaking capacity.
