The 0.8 A continuous rating sets the motor full-load current it protects — pair it with a motor drawing 0.8 A or less. Breaking capacity holds at 100 kA across 240 V, 400 V, 500 V, and 690 V AC (–), giving high fault-current headroom even on stiff 400 V distribution. Screw terminals accept solid conductors 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²), and stranded 2×(1…2.5 mm²) and 2×(2.5…6 mm²). The auxiliary switch is transverse design and field-installable. Zero clearance required at the back and sides — no ventilation gaps needed. Any mounting position works. Shock rated at 25 g for 11 ms. Front IP20 means finger-safe but not washdown.","metaTitle":"Siemens 3RV1021-0HA15-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-0HA15-ZX95 motor protection circuit breaker, 0.8 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V AC.
