CLASS 10 trip characteristic protects motors with short starting times. Breaking capacity: 100 kA at 240 V and 400 V AC, 42 kA at 500 V, and 6 kA at 690 V. Front protection is IP20; the enclosure is rated for any mounting position, with 0 mm clearance required at the sides and back. Terminals accept solid conductors: 2x (0.5–1.5 mm²) and 2x (0.75–2.5 mm²); stranded: 2x (1–2.5 mm²) and 2x (2.5–6 mm²).","metaTitle":"Siemens 3RV1021-1KA15-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1KA15-ZW96 SIRIUS motor protection circuit breaker, 12.5 A continuous rating, CLASS 10 trip, 100 kA breaking capacity at 400 V AC.
