Breaking capacity is a flat 100 kA across the full voltage range: 240 V, 400 V, 500 V, and 690 V AC. The unit includes factory-fitted transverse auxiliary contacts: 1 NO + 1 NC, rated for 100,000 mechanical/electrical operations. RoHS compliance date is noted as 10/01/2009, meaning the design meets EU Directive 2002/95/EC. No separate UL or CSA listing appears in the spec record, but the SIRIUS range typically carries IEC/EN 60947-2 and 60947-4-1 approvals; verify the specific certification mark on the unit if your panel requires UL 508 listing. ## Panel integration and fit Snap-on DIN rail mounting, no tools needed. Side-by-side mounting requires 30 mm clearance to adjacent devices for heat dissipation; zero clearance when using the side-by-side arrangement with the same S00 frame. The spring terminals accept ferruled or solid conductors — strip length is 8 mm for the cage clamp. The breaker integrates directly with SIRIUS contactors in sizes S00 and S0 via a screwless bus bar system, forming a compact motor starter assembly.","metaTitle":"Siemens 3RV2011-0CA25-ZX95 SIRIUS Motor Protection CB, 0.25","metaDescription":"Siemens SIRIUS 3RV2011-0CA25-ZX95 motor protection circuit breaker, 0.25 A, CLASS 10, 100 kA breaking capacity at 400 V, spring terminals, active production.

This is the standard class for protecting standard IEC induction motors against locked-rotor conditions."},{"question":"Will 3RV2011-0CA25-ZX95 drop into a panel wired for 3RV2011-0BA20?","answer":"Both are size S00 with the same 45 mm width and 35 mm DIN rail mounting, so the mechanical fit is identical. The key difference is the current range: the -0BA20 adjusts 0.14–0.2 A, while this -0CA25 adjusts 0.18–0.25 A. If your motor FLA falls within 0.18–0.2 A, it is a direct swap; below 0.18 A you need the -0BA20. The spring terminals on this unit are the same type as the -0BA20, so no rewiring of the main circuit is required."},{"question":"Where can I buy 3RV2011-0CA25-ZX95 and get a price?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
