Rated for a 24 V DC coil that draws 3.3 W both on pickup and hold — no power drop after closure, so the coil supply must be rated for continuous 3.3 W draw. Main and auxiliary circuits use spring-loaded terminals, accepting 2x (0.25... 2.5 mm²) solid or stranded, or 2x (24... 14) AWG — no screw torque to check, but the wire strip length must match the cage spec. Operational current at AC-12 (resistive load) is 10 A — that is the full-load current for general-purpose resistive switching. Motor power ratings: 4.5 kW at 500 V and 5.5 kW at 690 V — sized for a 3-phase induction motor in those voltage classes. Coil pickup at 0.85 x 24 V; dropout at 1.1 x 24 V. Pollution degree 3. IP20 on front and terminals. Operating temperature -25 to +60 °C. RoHS compliance date 01.07.2006.","metaTitle":"Siemens 3RT1016-2BB42 SIRIUS Contactor, 24 VDC Coil, 10 A AC","metaDescription":"Siemens 3RT1016-2BB42 SIRIUS power contactor, size S00, 24 VDC 3.3 W coil, spring-loaded terminals, 45 mm wide, IP20, -25 to +60 °C.
