The C0.3 curve means it handles moderate inrush currents typical of small motor or lighting loads — the 0.3 A nominal rating suits low-current DC control circuits or instrumentation supplies. The 2-pole construction simultaneously breaks both lines in a DC circuit. ## DC circuit breaker deployment Snap-on mounting to DIN rail per EN 60715 fits standard control-panel enclosures. The DC rating at 440V makes it a candidate for photovoltaic combiner boxes, DC drive bus protection, or battery-bank branch circuits. At 0.3 A, it protects low-current DC loads where a conventional AC MCB would lack the DC arc-quenching capability.","metaTitle":"Siemens 5SY5214-7CC12 MCB 2P C0.3 440V DC 10kA","metaDescription":"Siemens 5SY5214-7CC12 5SY5 series MCB, 2-pole C0.3 curve, rated 440V DC, 10kA breaking capacity.
