Rated operational voltage reaches 690 V AC, with the switching capacity holding at 100 kA across the 240 V to 690 V range (–). That SCCR headroom simplifies panel coordination — the breaker can be placed downstream of a transformer or main switch without derating. Screw-type terminals on the main circuit accept solid or stranded conductors: 2x 1–2.5 mm² or 2x 2.5–6 mm² per pole. The AWG equivalent is 2x 14–10 AWG. No auxiliary contacts are included, but the design accepts add-on blocks if needed. ## Integration and Deployment Mounting position is any orientation. Shock resistance is rated at 25 g for 11 ms, suitable for industrial machinery and panel-mounted applications subject to vibration. IP20 finger-safe protection on the front — adequate for enclosed panels; no washdown rating, so keep this inside a cabinet. The SIRIUS 3RV family is a well-established platform; no direct official successor has been published for this order code.","metaTitle":"Siemens 3RV1021-0EA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-0EA10-ZX95 motor protection circuit breaker, 0.4 A continuous rating, Class 10 trip, 100 kA breaking capacity at 400 V.
