Product details

It is a CLASS 10 device. Its 45 mm width and 97 mm depth fit standard panel layouts, and the spring-loaded terminals accept 2× (0.5 to 4 mm²) solid or stranded wire — no tool needed for termination, which cuts wiring time on a multi-motor panel. Rated operating voltage spans 20 to 690 V. The interrupting capacity at 400 V is 100 kA, giving solid SCCR headroom for most industrial distribution. At 690 V it still clears 4 kA, so it handles fault energy on 690 V line-fed motors. Ground fault detection is not included, so for ground-fault protection you'd add a separate module upstream.

Mounting position is any orientation. Required clearances: 50 mm above and below, 30 mm to the side, 0 mm forward and backward — so it can sit flush against a backplate or panel door. This matters when packing breakers tightly in a motor control center.

Frequently asked questions

Does this breaker have phase failure protection?

Yes, phase failure detection is built in. It will trip if one phase is lost, protecting the motor from single-phasing.

What compliance documentation is available for 3RV2011-1KA20-ZX95?

As a Siemens SIRIUS product, it carries CE, UL, CSA, and IEC certifications typical for motor protection circuit breakers. Specific declaration documents (RoHS, REACH) are available from Siemens on request.
