No ground fault detection on this variant. ## Terminal wiring and aux contacts Main current circuit terminals are screw-type. Solid conductors: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²). Stranded: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²). The auxiliary switch is transverse design and rated: 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V. No auxiliary contacts are included as standard — the auxiliary switch is built into the breaker body.","metaTitle":"Siemens 3RV1021-1FA15-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1FA15-ZW98 SIRIUS motor protection circuit breaker, 5 A continuous, Class 10 trip, 100 kA breaking at 400 V.
