Screw terminals on both the main and auxiliary circuits accept solid conductors from 0.5 mm² up to 2.5 mm² (two per clamp) and stranded up to 6 mm², covering the typical motor branch wiring range. Power dissipation at rated current is 7.25 W — a factor to include in the panel thermal budget when grouping several breakers. Zero clearance is required at the back and sides, so the breaker can be installed directly against adjacent devices without derating for air circulation. The auxiliary switch is a transverse design and is field-addable, allowing remote status indication without an extra module. Shock resistance is rated at 25 g for 11 ms, which covers the vibration profile of most industrial machinery and conveyor systems. The maximum operating frequency in AC-3 duty is 15 switching cycles per hour — adequate for motor start/stop applications but not for high-cycling loads like rapid reversing drives.","metaTitle":"Siemens 3RV1021-1DA15-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1DA15-ZW97 motor protection circuit breaker, 3.2 A continuous, Trip Class 10, 100 kA breaking at 400 V AC.
