Product details

The Siemens SENTRON 5SL4206-6 is a 2-pole miniature circuit breaker (MCB) with a B tripping characteristic, rated 6 A and 10 kA breaking capacity at 400 V AC per both EN 60898 and IEC 60947-2. Rated for 400 V AC multi-phase operation (max 440 V) at 50/60 Hz, with a DC rating up to 72 V.

Sealable design (can be locked in OFF position) and halogen-free / silicon-free construction — relevant for installations requiring low smoke emission or avoiding silicone contamination near sensitive electronics. Overvoltage category III, pollution degree 2, energy limitation class 3.

Frequently asked questions

What is the breaking capacity of 5SL4206-6?

10 kA at 400 V AC per both EN 60898 and IEC 60947-2 — the same rating under both standards, so no ambiguity for panel builders specifying to either code.

Will 5SL4206-6 drop into a panel specified for 5SL4363-7?

No — 5SL4363-7 is a 3-pole C-curve 63 A unit occupying 3 MW (54 mm), while the 5SL4206-6 is a 2-pole B-curve 6 A unit at 2 MW (36 mm). Different pole count, trip characteristic, current rating, and physical width; they are not drop-in substitutes without rewiring and re-coordination.

Where can I buy 5SL4206-6 and get current pricing?

Sourced and quoted to order against an RFQ through independent industrial-automation distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial offer.
