Product details

The Siemens SENTRON 5SQ2270-0KA10 is a 2-pole miniature circuit breaker rated 10 A at 400 V AC with a C tripping characteristic.

Occupies 2 width units (36 mm) on a DIN rail, with an installation depth of 55 mm — shallow enough to clear most enclosure back panels without crowding. IP20 finger-safe terminals suit enclosed distribution boards; no special sealing for washdown or outdoor exposure. The neutral conductor is switched internally (2-pole switching), so this breaker isolates both phase and neutral on fault or manual disconnect — a requirement in many regional wiring codes for final subcircuits.

Frequently asked questions

What is the breaking capacity of 5SQ2270-0KA10?

The breaking capacity is 3 kA according to EN 60898 at 400 V AC.

Where can I buy 5SQ2270-0KA10?

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

What is the difference between 5SQ2270-0KA10 and 5SU9304-1KK32?

The 5SU9304-1KK32 is an RCBO (RCD + MCB) with 30 mA residual current protection, rated 32 A, and a 10 kA breaking capacity — higher fault rating and adds earth-leakage protection. The 5SQ2270-0KA10 is a plain MCB with no RCD, lower 3 kA breaking capacity, and 10 A rating. They are not drop-in substitutes; the RCBO requires neutral connection and occupies a different width.
