Product details

The Siemens SIRIUS 3RV2011-0KA10 is a motor-protective circuit breaker designed for Class 10 trip characteristics, meaning it will trip within 10 seconds at 7.2× rated current — fast enough to protect standard induction motors during locked-rotor conditions without nuisance tripping on normal starts.

The interrupting capacity is rated 100 kA at 240 V, 400 V, 500 V, and 690 V AC — that covers high-fault utility feeds common in industrial plants. The screw-type terminals accept up to 2× 4 mm² stranded or solid, which covers most motor branch-circuit wiring up to 16 A.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, depth is 97 mm, height is 97 mm. It mounts on 35 mm DIN rail with screw or snap-on fastening, and requires 50 mm clearance above and below, 30 mm to the side, and zero forward or backward clearance.

Does this breaker detect phase failure?

Yes, phase failure detection is included, so the breaker will trip if one phase is lost, protecting the motor from single-phasing damage.
