The 0.8 A continuous current rating sets the motor FLA it protects — sized for a small motor drawing roughly 0.8 A at full load, corresponding to 0.18 kW at 400 V AC-3 duty. Ground fault detection is not included, so a separate ground-fault relay or GFCI breaker is needed if that protection is required. Depth is 96 mm from the rail to the front of the housing, which fits most standard enclosures with 120 mm or deeper back-panel clearance. Screw terminals accept 2x (1 to 2.5 mm²) solid or stranded, and 2x (2.5 to 6 mm²) for larger conductors, with AWG equivalents of 2x (14 to 10). The product carries RoHS compliance with a substance prohibition date of 01.05.2012, and REACH compliance is standard for Siemens SIRIUS components. The IP20 front protection and 6 kV surge voltage resistance are specified per IEC/EN 60947-2 and 60947-4-1 standards for motor protection circuit breakers. Shock resistance is rated at 25g for 11 ms.","metaTitle":"Siemens 3RV1021-0HA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-0HA10-ZX95 motor protection circuit breaker, 0.8 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V.
