The 24 VDC coil draws 10 A at rated voltage, with an operating range of 0.8 to 1.1 times nominal at 50 Hz and 0.85 to 1.1 at 60 Hz — meaning the coil holds in reliably even if the control supply sags to about 19 VDC. ## Mounting and integration — DIN rail, IP20, pollution degree 3 Pollution degree 3 rating confirms it handles conductive dust and humidity typical of industrial control cabinets without conformal coating. ## Termination and wiring — screw terminals, dual-wire capacity Main and auxiliary circuits use screw-type terminals accepting 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or up to 2x (0.75 to 4 mm²) max. AWG equivalents are 2x (20 to 16) solid, 2x (18 to 14) stranded, and 1x 12. This dual-wire capability simplifies daisy-chaining in motor starter assemblies without additional terminal blocks. ## Environmental and endurance — 30 million mechanical cycles, -25 to +60 °C Rated for 30 million mechanical operations, this contactor suits high-cycle applications like conveyor sorters or packaging machines. Side-by-side mounting is permitted, which helps when packing multiple contactors into a compact motor control centre.","metaTitle":"Siemens 3RT1016-1AM21 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1016-1AM21 power contactor, Size S00, 24 VDC coil, 10 A rated, screw terminals, IP20, DIN rail mount.
