The 32 A rating handles branch circuits feeding lighting, socket outlets, or small heating loads. B-curve avoids nuisance trips on loads with modest inrush (resistive heaters, incandescent lamps, general receptacles). The 3 kA breaking capacity matches typical domestic and light commercial available fault current; if your service entrance SCCR exceeds 3 kA, step up to a higher-rated series. IP20 finger-safe terminals — install inside a closed panel or distribution board. The 55 mm installation depth fits standard DIN-rail enclosures. Overvoltage category 3 and energy limiting class 3 mean it coordinates with downstream loads per IEC 60898.

Frequently asked questions
Where can I buy 5SQ2160-0KA32 and how do I get a price?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ through this listing.
What is 5SQ2160-0KA32's listed number of poles?
It is a 1-pole breaker (1P), switching a single phase.
What is 5SQ2160-0KA32's listed type of voltage?
The breaker is rated for AC/DC voltage, with a specific AC supply rating of 240 V at 50 Hz.
Will 5SQ2160-0KA32 drop into a panel specified around 5SQ2360-0KA16 without rewiring?
No — 5SQ2360-0KA16 is a 3-pole breaker (3P) rated 16 A at 400 V, while 5SQ2160-0KA32 is 1-pole at 32 A and 240 V. The pole count, voltage, and current ratings differ; the panel would need rewiring and possibly a different DIN-rail position.
