Product details

The Siemens SENTRON 5SY8463-7 is a 4-pole miniature circuit breaker with C-curve tripping characteristic, rated for 25 kA interrupting capacity at 400 V AC per IEC 60947-2 and 15 kA at 60 V DC per the same standard. It also carries a UL1077 listing at 5 kA, making it a dual-standard part for panels shipping to both IEC and North American markets.

Ambient range spans -40 °C to 75 °C, with derating on humidity: max 95% RH at 55 °C, tapering to 35% at 75 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, which suits rotating machinery environments.

Frequently asked questions

What is the interrupting capacity of 5SY8463-7?

25 kA at 400 V AC per IEC 60947-2, 15 kA at 60 V DC per the same standard, and 5 kA per UL1077.

Will 5SY8463-7 drop into a panel specified around 5SY4140-7 without rewiring?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint (4 modular width units), so the mechanical fit is identical. The difference is in ratings — check the interrupting capacity and curve against your BOM before swapping.

What compliance documentation does Siemens provide for 5SY8463-7?

The part is certified to IEC/EN 60947-2 and UL1077. It is halogen-free and silicon-free. Specific RoHS/REACH declarations are available from the manufacturer upon request.

Where can I buy 5SY8463-7 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ with target quantity; availability and pricing are confirmed at quote time.
