The unit also accepts an auxiliary switch (product extension auxiliary switch: Yes) for remote status feedback. Terminals accept solid and stranded conductors: 2x (1 … 2.5 mm²) and 2x (2.5 … 6 mm²), with AWG equivalents 2x (14 … 10). Depth is 96 mm, width 45 mm, height 97 mm — zero clearance needed at the back or sides for heat dissipation. Rated for a 0.75 kW motor at 400 V AC-3 duty, with a maximum operating frequency of 15 switching cycles per hour. Power dissipation at rated current is 7.25 W total (2.4 W per pole). Surge voltage resistance is 6 000 V. Storage and transport temperature range is -50 … +80 °C; operating range is -20 … +60 °C. Shock resistance: 25g / 11 ms. Compliance: RoHS substance prohibition date is 01 May 2012. Ground fault detection is not included — this is a standard motor-protective breaker, not a ground-fault device.","metaTitle":"Siemens 3RV1021-1BA10-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1BA10-ZW98 SIRIUS motor protection circuit breaker, 2 A continuous, CLASS 10, 100 kA breaking at 400 V.
