Any mounting position is permitted, and zero clearance is required at the sides or rear, so it can be packed tightly in a crowded enclosure. ## Terminals and wiring Screw-type terminals on both the main and auxiliary circuits. The main contacts 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), plus AWG 2x (14…10). The auxiliary switch is transverse and rated 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V.","metaTitle":"Siemens 3RV1021-1FA15-ZW95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1FA15-ZW95 motor protection circuit breaker, 5 A continuous, CLASS 10, 100 kA breaking at 400 V.
