At 1 A and 400 V AC, this MCB protects a branch circuit drawing under an amp — think a control transformer primary, a small power supply, or a signal-conditioner loop. For UL 489 or CSA C22.2 No. 235 applications, the 5 kA rating at the same voltage is the figure to use in your SCCR calculation. The DC rating is 72 V, so it's usable on DC control buses up to that voltage, but not on a 125 V DC battery bank. If your load has a motor start or a transformer inrush that peaks above 5 A for a few cycles, you'd want a C curve instead — this one will trip on that pulse. For mechanical engineering and industrial environments, as the suitability note states, it's rated for the vibration profile per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. That covers most panel-mounted gear on a machine base. The 3-module width (54 mm) fits standard per-pole spacing.","metaTitle":"Siemens 5SY4301-6CC SENTRON MCB, 1A, 3P, B Curve, 10kA","metaDescription":"Siemens 5SY4301-6CC SENTRON miniature circuit breaker, 1 A, 3-pole, B characteristic, 10 kA IEC breaking capacity.
