At DC the maximum rated voltage is 72 V, so it works in 48 V or 60 V DC auxiliary circuits common in rail and industrial control. The 2-pole format switches both line and neutral on a single-phase feed, or one pole per phase on a two-phase subfeed. Mounting position is any, which helps when you're packing breakers into a tight gland plate or a swing-panel layout. Sealable, halogen-free, and silicon-free — relevant for rail and aerospace specs where outgassing or contamination matters.","metaTitle":"Siemens 5SY4201-6CC11 SENTRON MCB, B Curve 1 A 2-Pole 10 kA","metaDescription":"Siemens 5SY4201-6CC11 SENTRON miniature circuit breaker, 1 A B-curve, 2-pole, 10 kA breaking capacity at 400 V AC.
