Breaking capacity sits at 100 kA at 240 V AC and 50 kA at 400 V AC, then drops to 3 kA at 500 V and 2 kA at 690 V — so for most 400 V line-side faults this breaker clears high-energy arcs without upstream coordination issues. The main circuit uses spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. Width is 45 mm, height 90 mm, depth 81 mm — fits a standard 45 mm module slot. IP20 on the front; no IP rating on the sides or back, so panel enclosure provides the environmental seal. Shock rated at 25g / 11 ms. Mounting position any.","metaTitle":"Siemens 3RV1011-1KA20-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1011-1KA20-ZX95 motor protection circuit breaker, 12 A continuous, 5.5 kW at 400 V, CLASS 10 trip, 50 kA breaking at 400 V.

The wiring difference is in the terminal type: the 1KA20-ZX95 uses spring-loaded terminals, while the 1HA10 uses screw terminals. If the panel was wired for screw terminals, you will need to adapt the conductor terminations — the spring clamp accepts 0.25–2.5 mm² solid or 0.25–1.5 mm² ferrule-stranded."},{"question":"What compliance documentation does this brand provide for 3RV1011-1KA20-ZX95?","answer":"Siemens SIRIUS breakers typically carry IEC/EN 60947-2 and 60947-4-1 certifications, plus UL/CSA listings for the North American market.
