It's designed for motor protection, includes phase failure detection, and trips on Class 10 overload curves, so it matches standard IEC motor starting profiles. At 45 mm wide, it fits a standard single-module slot in a panel. Screw terminals on both main and auxiliary circuits — solid wire 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²), stranded 2x (1... 2.5 mm²) or 2x (2.5... 6 mm²). The 0.4 A continuous rating sets the motor full-load current this breaker protects — pair it with a motor nameplated at or below that value. The 100 kA breaking capacity holds across 240 V, 400 V, 500 V, and 690 V, so it's suitable for installations with high available fault current without needing a current-limiting upstream device.","metaTitle":"Siemens 3RV1021-0EA15-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-0EA15-ZX95 motor protection circuit breaker, 0.4 A continuous, 100 kA breaking capacity at 400 V.
