The 45 mm width and 58 mm height fit standard S00 footprint enclosures. Depth of 73 mm leaves clearance for wiring and auxiliary contact blocks. Accepts solid or stranded conductors from 0.5 to 4 mm², with dual-wire capability up to 2x 2.5 mm². ## Switching performance and thermal limits Maximum switching frequency varies by duty: 1 000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor start/run), and 250/h at AC-4 (plugging/inching).","metaTitle":"Siemens 3RT2016-1AH02 SIRIUS Power Contactor, 24 VDC 10 A, S","metaDescription":"Siemens SIRIUS 3RT2016-1AH02 power contactor, 24 VDC coil, 10 A rated operational current, Size S00, screw terminals, snap-on DIN rail mounting.
