Product details

The Siemens SENTRON 5SL3206-6MB is a 2-pole miniature circuit breaker rated 6 A with a B tripping characteristic, breaking 4.5 kA per EN 60898 at 400 V AC. The 2-pole design switches both line conductors simultaneously, with no neutral switching (the neutral conductor is not switched on this unit).

Panel fit and peer delta

The closest peer in the same SENTRON family is the 1-pole 5SL3116-6MB (16 A, B-curve, 1 MW width). The 5SL3206-6MB is physically wider (36 mm vs 18 mm) and rated lower (6 A vs 16 A) but carries the same 4.5 kA breaking capacity and 400 V AC rating. If your panel was laid out for the 5SL3116-6MB, the 5SL3206-6MB will not drop in without rewiring: the 2-pole unit needs two line conductors and occupies double the DIN space. The depth (76 mm) and height (90 mm) are identical, so the enclosure depth is not a constraint.

Installation and environmental limits

The sealable feature (tamper-evident seal wire) is present for applications requiring locked settings.

Frequently asked questions

What is the breaking capacity of 5SL3206-6MB?

4.5 kA per EN 60898 at 400 V AC. That is the maximum fault current it can safely interrupt under the standard.

Will 5SL3206-6MB fit in a panel designed for 5SL3116-6MB?

Not without changes. The 5SL3206-6MB is 2-pole (36 mm wide) versus the 1-pole 5SL3116-6MB (18 mm wide), so it needs double the DIN rail space and two line conductors. Depth and height match at 76 mm and 90 mm respectively.

Where can I buy 5SL3206-6MB?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
