Product details

Dual-standard breaking capacity — what it means for panel design

The 5SY6506-6 carries both IEC/EN 60898-1 (6 kA) and IEC/EN 60947-2 (30 kA) ratings, plus UL 1077 and CSA C22.2 No. 235 (5 kA). This is the same dual-certification approach as the 5SL series, but the 5SY family adds a neutral-switching pole (1P+N) that the 5SL single-pole breakers lack. If your panel spec calls for disconnecting the neutral on a single-phase circuit, the 5SY6506-6 fits where a 5SL6006-7 would not.

Panel integration — dimensions and mounting

Snap-on mounting to DIN rail (EN 60715). Mounting position is any — horizontal, vertical, or flat — no derating required.

Frequently asked questions

Will 5SY6506-6 drop into a panel specified around 5SY4140-7 without rewiring?

Both are 2-MW-unit SENTRON breakers with the same 36 mm width and DIN-rail mounting, so the mechanical fit is identical. The key difference is tripping characteristic: 5SY6506-6 is B-curve, while 5SY4140-7 is a different curve — verify the coordination study before swapping. The terminal layout and busbar pitch are the same.

What compliance documentation does Siemens provide for 5SY6506-6?

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, supporting RoHS and REACH declarations.
