Product details

The quick-assembly fastening system and any-position mounting simplify rail placement in crowded enclosures.

Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) and mechanical endurance of 10 000 operating cycles typical. Compliant with IEC / EN 60898-1 and IEC / EN 60947-2, plus UL 1077 and CSA C22.2 No. 235 (5 kA at AC). The dual-standard marking means it carries both the domestic and industrial certifications, covering panel builds destined for European, North American, and Canadian sites.

Frequently asked questions

What compliance documentation does Siemens provide for 5SY6205-7?

The breaker is certified to IEC / EN 60898-1, IEC / EN 60947-2, UL 1077, and CSA C22.2 No. 235. It is halogen-free and silicon-free. Standard RoHS/REACH declarations are available from Siemens documentation.

Where can I buy 5SY6205-7 and how is it quoted?

The part is sourced to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead-time estimate.

Will 5SY6205-7 drop into a panel specified around 5SY5240-7 without rewiring?

Both are 2-pole SENTRON MCBs with the same 36 mm width and DIN-rail mounting, so the mechanical fit is identical. The 5SY6205-7 has a higher breaking capacity (30 kA vs the 5SY5240-7's typical 10 kA per IEC 60947-2), so it can replace the lower-rated unit without rewiring as long as the cable and busbar ratings are adequate for the higher fault current.
