Product details

Siemens 5SY5206-6KK11 — 2-pole B-curve MCB for railway and industrial panels

Breaking capacity is rated at 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, with a DC rating of 10 kA per EN 60898-2 and 15 kA per IEC 60947-2 at 440 V DC.

Panel integration and mounting notes

The 2-pole design does not switch the neutral — it's a line-only break for both poles. Installation depth is 70 mm, leaving 6 mm clearance behind the 76 mm body for wiring. Supply polarity matters for DC operation: AC can be connected as required, but DC polarity must be observed.
