The integrated transverse auxiliary switch (1 NO + 1 NC) gives a status signal back to the PLC or safety relay without needing a separate contact block. ## Breaking capacity — 100 kA across the board That means this breaker can sit upstream of a motor starter without worrying about cascading failure under a bolted fault — the SCCR headroom covers most industrial supply transformers. The 20...690 V rated operating voltage range lets it run on 400 V or 480 V distribution without a different variant. The spring terminals on the main circuit accept 2x (0.5...4 mm²) solid or stranded, or 2x (0.5...2.5 mm²) finely stranded with ferrule. No screwdriver needed for the power connections — strip to 8 mm, push the spring, insert the wire. The auxiliary switch terminals are also spring-loaded, same strip length. Side-by-side mounting at 0 mm spacing is allowed; no derating required for the 100 kA rating when ganged. RoHS compliant per the substance prohibition date of 10/01/2009. The SIRIUS 3RV series carries UL/CSA/CE/IEC certifications standard for motor-protective circuit breakers. The manufacturer provides a declaration of conformity and a full datasheet with time-current curves for coordination studies.","metaTitle":"Siemens 3RV2011-0KA25-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2011-0KA25-ZX95 motor protection circuit breaker, 1.25 A, CLASS 10 trip, 100 kA breaking capacity at 400 V, spring terminals, active production.

The -ZX95 variant adds the factory-fitted transverse auxiliary switch (1 NO + 1 NC) and spring terminals instead of screw terminals. No rewiring needed if the panel was laid out for the S00 form factor, but the spring terminals may require a different strip length or ferrule compared to the screw-clamp version."},{"question":"What is the rated voltage range of 3RV2011-0KA25-ZX95?","answer":"20 to 690 V AC, covering 240 V, 400 V, 480 V, and 690 V distribution systems without needing a different variant."},{"question":"What compliance documentation does this part carry?","answer":"RoHS compliant (substance prohibition date 10/01/2009).
