Product details

Compared to the 5SY7206-7CC (a 2-pole B-curve MCB), the 5SY8610-7 adds two more poles, a C curve, and a much higher breaking capacity (40 kA vs. the 6 kA typical of that series). If a panel was laid out for the 5SY7206-7CC, the 5SY8610-7 will not drop in without rewiring — it occupies 4 MW units (72 mm) instead of 2 MW, and the neutral conductor must land on the switched pole rather than a busbar.

At 72 mm wide (4 modular width units) and 76 mm deep, it fits standard distribution boards. The quick-assembly fastening system allows ganging with other SENTRON 5SY units. Combined top and bottom terminals simplify busbar feed-through. Rated IP20 with conductors connected — suitable for enclosed panel use, not open washdown areas.

Frequently asked questions

Where can I buy the 5SY8610-7 and get a price?

The 5SY8610-7 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will the 5SY8610-7 drop into a panel specified for the 5SY7206-7CC?

No — the 5SY8610-7 is 4-pole (3P+N) and 72 mm wide versus the 2-pole 5SY7206-7CC at 36 mm. The neutral must be wired to the switched pole, and the panel width and busbar arrangement need redesign.

What compliance documentation does Siemens provide for the 5SY8610-7?

The 5SY8610-7 is certified to IEC/EN 60947-2 and UL 1077. It is halogen-free and silicon-free. Standard Siemens declarations (CE, UKCA, RoHS, REACH) accompany the product.
