The car, the cable and the supply each cap the charge speed · review

Tera W01, 11 kW, 16 A, 400 V, integrated DC 6 mA protection, 7 m review

An 11 kW charger with integrated 6 mA DC residual current detection and a stated requirement for an external Type A breaker, CE and TÜV certified, with a 7 metre cable and holder.

By Jean-Benoit Buisson

The bottom line The only charger on this shelf that says what has to be installed alongside it, and explains why its own protection is sufficient in combination. That single line is worth more than the app features on seven of its neighbours.

An 11 kW charger that talks about the installation rather than only about itself.

The sentence nobody else writes

Integrated DC 6 mA residual current detection, with an external Type A breaker required. That is a complete statement about protection: what the charger does, and what must exist upstream for the combination to work.

An electric vehicle can produce a DC fault current that blinds a standard Type A device. A charger that detects it at 6 mA is why a Type A remains acceptable rather than a costlier Type B. Eight chargers on this shelf and one explains this.

The certifications

CE and TÜV, with a German manual supplied and all product certificates stated as available. TÜV is a body; the AIMILER on this shelf names a connector standard instead.

The scheduling

On the unit itself or through a dedicated application, which means the charger works when the phone does not.

What it does not do

Solar surplus charging, which two chargers here offer. And consumption metering, which none of the eight describes properly.

Availability

German, French, Italian and Spanish Amazon stores quoted 280 € to 399 € when this page was compiled.

British Amazon store carries it too, priced in its own currency, which the euro range above deliberately omits.

American Amazon store returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

These figures are what Keepa reported on the day this page was last updated. Availability and pricing move without notice.

What it gets right, and what it leaves out

Strengths

It states what protection must exist upstream — an external Type A breaker — rather than leaving it unsaid
Integrated 6 mA DC fault detection, which is what a Type A breaker cannot see
CE and TÜV certification named, with a German manual supplied

Compromises

The second bullet is about product certificates and support rather than the product
No solar surplus charging
No consumption metering described

Questions owners ask about this one

Why does 6 mA DC detection matter?

Because an electric vehicle can produce a direct-current fault that a standard Type A residual current device cannot detect, and which can blind it. A charger with integrated 6 mA DC detection handles that, which is why it is permitted alongside a Type A rather than requiring a more expensive Type B.

Does that mean no other protection is needed?

No. The first bullet says an external Type A breaker is required alongside it. What a specific installation needs is set by the national wiring rules and by whoever is qualified to assess it, and this page reports the maker’s statement rather than extending it.
