The 0.8 A continuous current rating sets the thermal pickup for motor overload protection — this breaker is sized for small motors drawing under an amp at full load. Breaking capacity of 100 kA at 400 V AC (also 100 kA at 240 V, 500 V, and 690 V AC) covers virtually any installation fault level without needing upstream fuses. The auxiliary switch (transverse design) provides a signal contact rated 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V — enough for PLC or relay feedback. Power dissipation at AC in hot operating state is 7.25 W — factor this into enclosure thermal calculations when grouping multiple breakers. Width 45 mm, height 97 mm, depth 96 mm — fits a standard 45 mm-wide DIN-rail slot with zero clearance needed at the sides or back. Shock resistance rated at 25 g for 11 ms — suitable for mounting on machinery subject to vibration.","metaTitle":"Siemens 3RV1021-0HA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1021-0HA15 SIRIUS motor protection circuit breaker, 0.8 A rated current, Trip Class 10, 100 kA breaking capacity at 400 V AC, screw terminals, DIN rail mount.
