Snap-on mounting onto 35 mm DIN rail per DIN EN 50022, with screw-type terminals for both main and auxiliary circuits — the main terminals accept 2x (0.5…1.5 mm²) solid or 2x (1…2.5 mm²) stranded, and the auxiliary terminals share the same range. For a BOM freeze or critical-spare holding, this part is a safe choice: no imminent obsolescence, and the SIRIUS family has long lifecycle support typical of Siemens industrial controls. Auxiliary contact ratings: 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V — these are the switching limits for the signal contacts, not the main power path. If you need to switch a 24 VDC PLC input, 1 A is ample; for a 230 VAC contactor coil, 0.5 A covers most small contactors. Operating frequency at AC-3 duty is 15 operations per hour maximum — this is a motor-protection device, not a cycled load switch; it is designed to trip on fault, not to serve as a daily start-stop contactor. Rated insulation voltage is 690 V, and the device is rated for AC-3 duty up to 690 V — suitable for 400 V and 480 V systems with headroom. Shock resistance rated at 25 g for 11 ms — survives shipping and typical industrial vibration. Substance prohibitance date of 05/01/2012 aligns with RoHS compliance — the part is RoHS-compliant and REACH-registered as standard for Siemens industrial controls.","metaTitle":"Siemens 3RV1021-1AA15 SIRIUS Motor Protection CB, 1.6 A, CLA","metaDescription":"Siemens SIRIUS 3RV1021-1AA15 motor-protection circuit breaker, 1.6 A continuous, CLASS 10 trip, 100 kA at 400 V AC.
