Breaking capacity is 50 kA at 400 V AC, dropping to 10 kA at 500 V and 4 kA at 690 V. ## Integration Notes Width is 45 mm. Depth is 96 mm, height is 97 mm. Screw terminals on the main circuit accept solid or stranded wire: 2x (1 … 2.5 mm²) and 2x (2.5 … 6 mm²) per pole. That covers most motor feeder cables up to 6 mm² (roughly 10 AWG). No auxiliary contacts are included — the unit has zero built-in aux contacts, so if you need a status signal, you'll add the separate auxiliary switch block (the listing confirms auxiliary switch is available as an add-on). Ground fault detection is not included, so for sensitive ground-fault protection you'd need an external module or a different breaker. Shock resistance is 25g / 11 ms, which is adequate for most industrial environments but not for extreme vibration like near a large reciprocating compressor without additional damping.","metaTitle":"Siemens 3RV1021-4CA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-4CA10-ZW97 motor protection circuit breaker, 22 A continuous, CLASS 10 trip, 50 kA breaking at 400 V.
