Product details

The Siemens SENTRON 5SN6206-8CP is a 2-pole miniature circuit breaker (MCB) from the 5SN series, rated for 400 V AC at 50 Hz.

Two-pole switching means it simultaneously opens both live conductors — required for 230 V line-to-line loads or where double-pole isolation is specified. Rated voltage of 400 V AC with multi-phase operation and 440 V AC maximum covers standard 400/230 V three-phase systems. The 72 V DC maximum limits DC use to control circuits, not traction batteries. Mechanical endurance of 10 000 operating cycles is typical for an MCB; it is not a contactor for frequent switching.

Panel integration

Snaps onto DIN rail in a standard 36 mm width, occupying 2 modular width units. Accepts solid conductors up to 35 mm² — enough for 16 A through 25 A feed-through in a distribution board.

Frequently asked questions

Where can I buy 5SN6206-8CP and how do I get a price?

The 5SN6206-8CP is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 5SN6206-8CP drop into a panel that was specified around 5SY5202-6 without rewiring?

Yes. Both share the same 76 mm depth, 36 mm width, 90 mm height, 70 mm installation depth, and 2-module DIN-rail footprint. The 5SN6206-8CP uses the same terminal range (solid up to 35 mm²) and mounting position. The key difference is breaking capacity: the 5SN6206-8CP is rated 6 kA per EN 60898, while the 5SY5202-6 is rated 10 kA per the same standard. If the panel's fault level is below 6 kA, the swap is mechanical and electrical drop-in.

What compliance documentation does Siemens provide for 5SN6206-8CP?

As a SENTRON series MCB, the 5SN6206-8CP is designed and tested to EN 60898 and IEC 60947-2. Standard documentation includes a CE declaration of conformity and the manufacturer's datasheet. RoHS and REACH compliance declarations are available from Siemens on request.
