Product details

The 10 A rated current at 240 V AC on a 50 Hz network is the continuous load it can carry without nuisance tripping. The single-pole form factor with no neutral pole switching means this breaker protects only the phase conductor — the neutral is solidly connected through the busbar. It occupies one modular width unit on the DIN rail, so it fits a standard 18 mm slot. IP20 finger-safe terminals are standard for panel-internal wiring; no washdown or outdoor rating here.

Deployment context in a panel

The single-pole width keeps the rail fill factor tight — you can pack 18 of these across a 360 mm rail section. The B-curve 10 A rating is a common choice for lighting circuits, general-purpose socket outlets, and control transformer primaries where the inrush stays under 50 A. Because it's a 1-pole device with no neutral switching, it pairs with a separate solid neutral bar on the same DIN assembly.

Frequently asked questions

Where can I buy the 5SQ2160-0KA10 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead-time estimate. No stock count or price is listed here because both fluctuate with market conditions.

What are the key ratings of the 5SQ2160-0KA10?

It is a 1-pole miniature circuit breaker with B characteristic, rated 10 A at 240 V AC, 50 Hz, with a 3 kA breaking capacity per EN 60898. It occupies 1 modular width unit (18 mm) and installs to a 55 mm depth on DIN rail. Pollution degree 3 and overvoltage category 3 apply.

Will the 5SQ2160-0KA10 drop into a panel specified for the 5SQ2170-2YA15 without rewiring?

Yes, the physical footprint is identical — both are 1-pole, 1 modular width unit, 55 mm depth, same DIN-rail mounting. The difference is the tripping characteristic: the 5SQ2170-2YA15 has a C curve (magnetic trip at 5 to 10 times rated current) and a 1.6 A rating, while the 5SQ2160-0KA10 is a B curve at 10 A. If the panel wiring and load are designed for a 10 A B-curve breaker, it swaps in. If the original design called for a 1.6 A C curve, the 10 A B curve will not provide the same overcurrent protection — verify the branch-circuit load and coordination before swapping.
