DIN rail contactor with wide AC/DC coil range
The 3RT2628-1NP35 is a Siemens contactor accepting a 200-280 V AC/DC coil at 50/60 Hz, so it works across both AC and DC control circuits without a separate rectifier or coil change-out — one part number covers mixed-voltage panels. Screw-type coil terminals and main power connections: solid wire up to 2x 4 mm² or stranded 2x 10 mm², with ring-tongue capability at 40 °C for 1x 16 mm² and at 60 °C for 1x 25 mm² — covers most panel wiring from control to load side without adapter lugs.
Switching frequency and thermal limits
Maximum switching rate drops with applied voltage: 100 operations per hour at 230/240/400 V, 70/h at 480 V, 65/h at 500 V, 45/h at 600 V, and 36/h at 690 V — the thermal capacity of the coil limits cycle rate at higher voltages. Operate and release times are 30-50 ms for both AC and DC coil supplies — consistent switching speed regardless of control voltage type, simplifying timing coordination in sequence circuits.
Environmental and sourcing
Dimensions: 45 mm wide, 150 mm high, 165 mm deep — fits standard 35 mm DIN rail footprint with clearance for screw-terminal wiring access on all sides.
