Breaking capacity is 100 kA at 240 V, 400 V, and 500 V AC, dropping to 8 kA at 690 V AC. Screw-type terminals for the main current circuit accept solid conductors: 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²). Stranded conductors: 2×(1…2.5 mm²) and 2×(2.5…6 mm²). The auxiliary switch is transverse design; the breaker includes an auxiliary switch (yes) but no auxiliary contacts for the main circuit (0). No ground-fault detection. Trip class CLASS 10 matches most standard motor starting profiles. Shock rated at 25g / 11 ms. Mounting position any.","metaTitle":"Siemens 3RV1021-1DA15-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1DA15-ZW96 motor protection circuit breaker, 3.2 A continuous current, CLASS 10 trip, 100 kA breaking capacity at 400 V.
