When power just needs to work.

No one on a construction site says: “Hopefully it works today.”
It has to work. That’s it.

At seven in the morning, the smell of damp concrete fills the air. Dust floats around. Someone starts a 400V concrete mixer, right next to it a 230V grinder kicks in. In the workshop, a compressor powers up. In the garden, a PV installer connects an inverter for testing.

And it all comes down to one question:
can the power supply handle it?

This is exactly where the TD Series Distribution Boards come in.
It’s the first Doktorvolt® series. The one developed the longest. The one most tested in real conditions.

Not because it’s the oldest.
Because it has been refined again and again—until it stopped surprising anyone.

And in electrical work, no surprises is the highest compliment.

TD Series – a foundation, not a novelty

In theory, it’s a construction distribution board. Some simply call it a “site box.”
In practice, it’s the point where energy stops being chaos.

Over a hundred variants. Different configurations of 230V and 400V sockets. Models with RCD protection. Versions with increased sealing, including IP65. Compact setups as well as more advanced configurations.

This isn’t just one box.
It’s a system designed for real-life scenarios.

On a residential construction site, the TD series organizes circuits and stabilizes the operation of multiple machines at once. In the garden, it powers a mower, pump, lighting, and tools without the risk of overload. In a workshop, it distributes the load so nothing trips at the worst possible moment.

The TD Series doesn’t try to impress.
It’s built to perform.

What sets it apart in practice?

Not a brochure. Not a slogan. Mechanics.

The socket layout is logical. The circuits are separated in a way that actually makes sense. Protection devices – both overcurrent and residual current – are standard, not optional. That means a TD Series distribution board doesn’t just distribute power—it actually controls it.

Models with IP65 enclosures handle moisture and dust without issues. You don’t need to cover them with plastic at the first sign of rain. And when you’re working outdoors, that matters more than any dry catalog description suggests.

What do you actually gain?

Time. Safety. Predictability.

These aren’t marketing buzzwords. They’re real outcomes: fewer interruptions, less frustration, and a lower risk of equipment damage.

With over 100 variants available, you’re far more likely to find a model that fits your exact scenario—instead of adjusting your workflow to fit the equipment.
