Product details

The Siemens SENTRON 5SQ2170-0KA02 is a 1-pole miniature circuit breaker with a C tripping characteristic, rated at 2 A and 3 kA breaking capacity per EN 60898 at 240 V AC, 50 Hz. It occupies a single width unit on a DIN rail — fits a standard 18 mm slot in a distribution board or panel.

Panel integration

Installation depth is 55 mm — standard for a modular DIN-rail device, no extra clearance needed behind the panel. IP20 rated, intended for dry indoor enclosures, not washdown areas.

Frequently asked questions

Where can I buy 5SQ2170-0KA02 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of 5SQ2170-0KA02?

3 kA per EN 60898 at 240 V AC, 50 Hz — sufficient for most final subcircuits in residential and light commercial distribution boards.

What does the C tripping characteristic mean for this breaker?

The C-curve (energy limiting class 3) trips at 5 to 10 times rated current, so it handles moderate motor or lighting inrush without nuisance trips.
