That 10 kA SCCR means it can safely clear a fault up to 10,000 A without welding its contacts or cascading the fault upstream — important for selectivity in a residential or light commercial distribution board where the upstream main breaker is typically rated higher. This MCB occupies 2 modular width units (36 mm) on a standard DIN rail, with a depth of 76 mm and a 70 mm installation depth — it sits flush with the rail and leaves room for wiring behind the panel door. Vibration resistance to 50 m/s² at 25–150 Hz per IEC 60068-2-6 means it holds up on a machine panel or in a mobile installation. At 30 °C ambient, the MCB carries its full 1 A rating. At 40 °C it derates to 0.95 A, at 45 °C to 0.92 A, and at 50 °C to 0.89 A. By 55 °C you're down to 0.86 A.","metaTitle":"Siemens 5SL4201-7CC SENTRON MCB, 2-pole C-curve 1 A 10 kA","metaDescription":"Siemens 5SL4201-7CC SENTRON miniature circuit breaker, 2-pole, C-curve, 1 A, 10 kA at 400 V AC.
