That makes it the right choice for motor starter feeders, control transformers, and lighting panels where the load draws a moderate magnetizing surge. Rated operating voltage is 400 V AC (440 V multi-phase or single-phase) and 880 V DC, with a maximum DC operating voltage of 1 000 V. The IP20 rating applies with connected conductors — the terminals are finger-safe only when wired. Combined top and bottom terminals allow daisy-chaining busbars without extra jumpers. Operates across -40 °C to 75 °C ambient, with humidity limits of 95% up to 55 °C, derating to 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — survives shipping and fan vibration in industrial cabinets.","metaTitle":"Siemens SENTRON 5SY5463-7 MCB, 4P C-Curve, 10 kA IEC/UL, 76","metaDescription":"Siemens SENTRON 5SY5463-7 miniature circuit breaker, 4-pole C-curve, 10 kA breaking capacity per IEC/EN 60898-2 and UL1077.

On DC circuits it delivers 10 kA per EN 60898-2 and 15 kA per IEC 60947-2."},{"question":"What compliance documentation does Siemens provide for 5SY5463-7?","answer":"The 5SY5463-7 is listed to IEC/EN 60898-2 and UL1077. It is halogen-free and silicon-free. The manufacturer provides standard compliance documentation including RoHS and REACH declarations upon request."},{"question":"How do I get current pricing and availability for 5SY5463-7?","answer":"The 5SY5463-7 is sourced and quoted to order against an RFQ through independent distribution.
