The auxiliary switch contact is included on the device — no separate add-on module needed for status feedback to the PLC or annunciator. Dimensions are 45 mm wide, 97 mm tall, 96 mm deep — fits the standard SIRIUS 45 mm footprint, same as the 3RV1011 frame. Main circuit terminals are screw-type, accepting solid or stranded copper: 2x (1 … 2.5 mm²) or 2x (2.5 … 6 mm²) per clamp, with AWG equivalents of 2x (14 … 10).","metaTitle":"Siemens 3RV1021-1CA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1CA10-ZX95 SIRIUS motor protection circuit breaker, 2.5 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V.
