Product details

The Siemens 5SY6208-8CC is a SENTRON miniature circuit breaker — 2-pole, D tripping characteristic, rated 8 A with a 6 kA breaking capacity per EN 60898 at 400 V AC.

Ratings & Fit

Breaking capacity is 6 kA per EN 60898 at 400 V AC, and 5 kA per UL 1077 / CSA C22.2 No.235 — enough for most commercial and light industrial panelboards. The 2-pole design (2 MW) switches both phase conductors; neutral is not switched. The operating temperature range spans -40 °C to 75 °C, with derating for humidity (max 95% 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.

Frequently asked questions

Where can I buy the 5SY6208-8CC and get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for current pricing and availability; a quote will be confirmed at that time.

Will the 5SY6208-8CC drop into a panel specified around the 5SY4304-7CV?

Yes — both are 2-pole, 2 MW units with the same 36 mm width and DIN-rail mounting. The physical footprint is identical, so no rewiring of the busbar or enclosure is needed. The difference is the current rating (8 A vs 4 A) and breaking capacity (6 kA vs 10 kA).

What compliance documentation does Siemens provide for the 5SY6208-8CC?

The breaker carries ratings per EN 60898 and UL 1077 / CSA C22.2 No.235, indicating IEC and North American market compliance. It is halogen-free and silicon-free. Specific RoHS/REACH declarations are available from Siemens upon request.
