Rated operational current at AC-12 (resistive load) is 10 A maximum. For motor duty, the contactor is rated 4.5 kW at 500 V and 5.5 kW at 690 V. Under AC-2 duty (slip-ring motors) at 400 V, it handles 4 kW; under AC-4 (plugging/reversing) at 400 V, the rated current is 8.5 A. These are the figures that decide fit for a given motor nameplate — not the AC-12 number. Main and auxiliary circuits use screw-type terminals. Solid or stranded wire acceptance: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). AWG equivalents: 2x (20 to 16), 2x (18 to 14), 1x 12. For coordination 1 (no damage to the contactor), the fuse is gL/gG 35 A. These are the values to hand to the panel designer for selectivity studies.","metaTitle":"Siemens 3RT1016-1BB42-0AA1 SIRIUS Power Contactor, 24 VDC, S","metaDescription":"Siemens SIRIUS 3RT1016-1BB42-0AA1 power contactor, size S00, 24 VDC coil, 45 mm wide.
