The 18 mm width (1 width unit) fits tight panel layouts. Halogen-free and silicon-free construction. Sealable for tamper-evident installations. Touch protection is built in. Rated for overvoltage category III. Suitability for operation listed as residential buildings and infrastructure. No neutral conductor switching function — this is a single-pole DC breaker. The DC voltage rating of 220 V DC maximum makes it a fit for telecom rectifier outputs, solar combiner boxes, or DC bus distribution in smaller installations.","metaTitle":"Siemens 5SL5125-7RC SENTRON MCB, 1-pole DC, C-curve 25 A, 22","metaDescription":"Siemens 5SL5125-7RC SENTRON miniature circuit breaker, 1-pole DC, C tripping characteristic, 25 A, 220 V DC, 10 kA breaking capacity.
