The unit also includes phase failure detection, so a lost phase on the line side will trip the breaker before the motor single-phases. Any mounting position is allowed. Terminals accept solid wire 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²), or stranded 2x (1...2.5 mm²) and 2x (2.5...6 mm²).","metaTitle":"Siemens 3RV1021-0FA15-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0FA15-ZW98 SIRIUS motor protection circuit breaker, 0.5 A continuous, CLASS 10 trip, 100 kA SCCR at 400 V.
