The 3RT1034-1DW48-0PA6: The coil is rated 48 V DC, with an operating time of 20 to 30 ms and an arcing time of 10 to 15 ms — meaning it pulls in fast and extinguishes the arc quickly, which matters for DC control circuits where contact erosion is a concern.
For motor duty, the AC-3 rating at 500 V is 18.5 kW and at 690 V is 10 kW — these are the numbers you use for sizing a contactor to a standard three-phase induction motor. For DC switching, the DC-13 ratings tell you the inductive load capability: 10 A at 24 V, 2 A at 60 V, 6 A at 230 V, and 3 A at 400 V. These are the values that govern contact life when switching DC solenoids or brake coils — the DC arc is harder to extinguish than AC, so the current is derated as voltage rises. Maximum switching frequency at AC-3 duty is 1,000 operations per hour.
The S2 frame size gives a width of 95 mm, height of 112 mm, and depth of 130 mm — check your enclosure depth before committing; 130 mm is deeper than a typical S0 contactor. Main circuit connections are screw-type terminals accepting 2x (0.75 to 16 mm²) solid or stranded. The control circuit accepts 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, with a maximum of 2x (0.75 to 4 mm²). Minimum permissible conductor cross-section at 40 °C is 16 mm² for the main circuit.
As a Siemens SIRIUS product, it carries the usual CE marking for the European market and is designed to IEC/EN 60947-4-1 standards for contactors and motor-starters.
