The load circuit accepts 48 to 460 V AC, and the control input is 4 to 30 V DC — a wide-range logic-compatible coil that covers 5 V, 12 V, and 24 V PLC outputs without a dropping resistor. Connection is via ring cable lugs, which means the contactor lands on a stud or busbar rather than a spring-cage terminal; factor that into your panel wiring plan. This is not an AC-3 motor-switching figure; for inductive motor loads you derate significantly or step to the 3RF34 series. The 48-460 V load range covers standard three-phase line voltages (208, 240, 400, 480 V) on a single pole. The 4-30 V DC control input is a single-supply range: no separate coil voltage variant to order, and it triggers cleanly from a 24 V DC PLC output card or a 5 V logic signal. The 3RF3320-3AA44 carries an active lifecycle status — it is a current-production catalog item, not a phase-out or NRND line. RoHS compliance is confirmed since 15 January 2024. No official successor is listed because none is needed — this is the current build state. ## Panel and wiring integration Packaging dimensions are 105 x 27 x 122 mm — a narrow 27 mm footprint that clips onto a standard 35 mm DIN rail, leaving adjacent slots free for overload relays or terminal blocks. The ring cable lug connection means each power terminal expects a crimped ring lug on a stud; keep a crimp tool and M4/M5 ring lugs on the build cart. No auxiliary contact block is integrated on this base unit, so if you need status feedback, add a 3RF3900-0A series accessory block on top.","metaTitle":"Siemens 3RF3320-3AA44 SIRIUS 3RF33 Solid-State Contactor, 20","metaDescription":"Siemens 3RF3320-3AA44 SIRIUS 3RF33 solid-state contactor, 1-pole, 20 A AC-1 at 40 °C, 48-460 V load, 4-30 V DC control, ring cable lug connection.
