Mounts in any position; the quick-assembly system means no tools for the rail clip. IP20 with conductors connected, so it's a panel-interior part, not a field-mounted disconnect. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — survives the floor of a typical machine skid.","metaTitle":"Siemens 5SY7350-7CC SENTRON MCB, 3P, C-Curve, 50 A, 400 V","metaDescription":"Siemens SENTRON 5SY7350-7CC miniature circuit breaker, 3-pole, C-curve, 50 A, 400 V AC, 20 kA IEC breaking capacity.

The IEC figure handles most industrial distribution subfeeds; the UL figure governs North American supplementary-protection installations."},{"question":"What is the closest functional second-source to 5SY7350-7CC?","answer":"The 5SY4140-7 series is a functional peer in the same SENTRON family — same 3-pole C-curve form factor, but different current ratings. The 5SY7350-7CC is a 50 A variant; the 5SY4140-7 covers lower current values. They share the same DIN-rail footprint and modular width, so a panel designed for one can accept the other without rewiring, provided the current rating matches the load."},{"question":"Where can I buy 5SY7350-7CC?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
