This means it protects DC circuits — common in solar arrays, battery banks, or DC bus systems — from overcurrents and short circuits up to 10,000 amps. The 0.5 amp rating makes it a fine choice for control circuits, signal wiring, or low-current branches where a standard 1A or 2A breaker would be too coarse. Two poles means it occupies 36 mm of rail width (two 18 mm modules). The DC rating at 440V is key — most MCBs derate significantly on DC; this one holds its full 10kA interrupting capacity at that voltage, so it's sized for 400V-class battery strings or DC bus feeders without needing a series-connected second breaker.","metaTitle":"Siemens 5SY5205-7CC12 MCB, 440V DC 10kA 2P C0.5, current pro","metaDescription":"Siemens 5SY5205-7CC12 miniature circuit breaker, 2-pole C0.5 curve, rated 440V DC at 10kA breaking capacity.
