Here&rsquo;s the thing: we run it on 400V three-phase because it spreads the load evenly across all three legs. That keeps the wiring size and contactor stress manageable, while still packing serious wattage into a compact tube.</p> <h3 id="power-voltage-and-sizewhy-it-all-clicks">Power, voltage, and size—why it all clicks</h3> <p>You get 2500W packed into a 300mm tube. That’s high watt-density, exactly what you need when space is tight. And running at 400V brings the amperage down compared to a 230V option at the same power. So you can use smaller wires and cut voltage drop over longer runs. The 300mm length hits a sweet spot: long enough to cover the heating zone, short enough to squeeze into crowded enclosures and get you up to temp quicker.</p>
