The 690 V AC-3 rating covers most European 400 V motor circuits with headroom for 690 V applications. The 45 mm width (3 modules) fits standard enclosure cutouts for Size S0 breakers. Screw-type terminals on both main and auxiliary circuits accept 2x (0.5...1.5 mm²) solid/stranded or 2x (0.75...2.5 mm²) with ferrules; AWG equivalents 2x (16...12) and 2x (14...8) for mains, 2x (20...16) and 2x (18...14) for auxiliaries. Terminal torque: 2...2.5 N·m. Relative humidity 10 to 95 % during operation. Shock resistance 25 g / 11 ms per IEC 60068-2-27. Substance prohibition date 05/01/2012 — RoHS and REACH compliance documentation is standard for this brand and order code.","metaTitle":"Siemens 3RV6021-4AA15 SIRIUS Motor Protection CB, 16 A, Clas","metaDescription":"Siemens 3RV6021-4AA15 SIRIUS motor protection circuit breaker, 16 A rated current, Trip Class 10, Size S0, 690 V AC-3, screw terminals, DIN rail mount.
