The coil is 24 VDC, pulling 3.3 W both during pickup and holding — no inrush spike to size your control transformer around. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded copper, or 2x (24 to 14 AWG). Side-by-side mounting is allowed — no derating required for zero-gap spacing — but keep 6 mm clearance to grounded metal on the front and sides for the IP20 finger-safe enclosure. The AC-3 rating (4.5 kW at 500 V, 5.5 kW at 690 V) is the one that governs motor switching — it tells you the contactor can break the motor's locked-rotor current without welding. For resistive loads (AC-1), the maximum operating current is 10 A (AC-12). AC-4 duty at 400 V is rated at 8.5 A, covering plugging and inching applications where the contactor interrupts full-load current. Built-in varistor surge suppression across the coil — no external snubber needed for the 24 VDC circuit.","metaTitle":"Siemens 3RT1016-2DB44-ZW96 SIRIUS Contactor, 24 VDC, 5.5 kW","metaDescription":"Siemens 3RT1016-2DB44-ZW96 SIRIUS power contactor, size S00, 24 VDC coil, spring-loaded terminals, rated 5.5 kW at 690 V.
