The AC/DC voltage type means the same breaker works on either supply, but the 3 kA breaking capacity is rated at AC; verify DC performance against your system voltage and fault current.","metaTitle":"SENTRON 5SQ2370-2YA01 Miniature Circuit Breaker, 3-Pole, C 1","metaDescription":"SENTRON 5SQ2370-2YA01 miniature circuit breaker, 3-pole, C-curve, 1 A rated current, 3 kA breaking capacity at 400 V AC.
