It hunts down the data hidden in your switchboards
A portable three-phase measurement case. Installed in under an hour, with no shutdown and without touching the installation.
The case in detail
Non-intrusive, end to end
- Flexible probes closed around the conductors: no rewiring, no shutdown
- Automatic installation check: reversed probe, phase rotation, phase presence
- Front-panel indicators: phase order, dangerous voltage on neutral or earth
- Remotely managed: no recurring site visits
- Currents, voltages, power, energy, frequency, power factor, neutral
A case next to the switchboard, one probe per phase
The VISU Box sits at the foot of the main switchboard or cabinet. Flexible probes go around the cables of the feeders to monitor, up to 9 at a time.
One flexible probe per phase, closed around each feeder cable. No shutdown, no rewiring.
Placed near the switchboard, it handles up to 9 three-phase feeders. A standard 400 V socket powers it.
Measurements are sent over a secure link: curves, alerts and reports, remotely.
Six steps, a few minutes per feeder
The first curves appear on VISU Live a few minutes after power-up.
1. Place the case
Close to the switchboard, on a stable and dry surface, lid open and accessible.
2. Power the VISU Box
Plug the 400 V connector (3P+N+E) into an available socket. Check the three phase indicators.
3. Fit the probes
Open the flexible probe, wrap it around the conductor, close it. No shutdown.
4. Respect the direction
The probe arrow points towards the load. A reversed probe is flagged automatically.
5. Connect and label
Plug each probe into its channel, 1 to 9, and note which feeder it measures.
6. Check the data
Curves appear on VISU Live. The installation check confirms the setup.

The VISU Box, in questions
The intelligence sits in the case. The platform centralises, compares and reports.
How many feeders does a VISU Box monitor?
Up to 9 three-phase feeders, simultaneously. Three flexible probes per feeder, one per phase.
Do I need to cut the power to install it?
No. The flexible probes close around the cables, nothing is disconnected. Installation takes under an hour and an automatic check validates the wiring.
Where is the data computed?
In the case. Power, power factor, harmonics and imbalance are computed on site, right next to the switchboard: this is edge computing. VISU Live receives data that is already processed.
What if the internet connection drops?
Measurement continues. The case stores the data in memory and sends it as soon as the link is back. No data is lost.
Can I read the measurements without internet?
Yes. The case's screen displays the measurements on site.
Do alerts depend on the cloud?
No. Threshold overruns are detected in the case. The platform then notifies your teams by email or on mobile.
Is VISU Live a cloud platform?
Yes: VISU Live is an online platform, hosted in the European Union, accessible from a browser or smartphone. It centralises history, compares sites and produces reports. But measurement and computation do not depend on it: they happen in the case.
Is my data protected?
Secure link, EU hosting, named accounts with per-tab permissions, connection log and off-site backup.
How is the case powered?
From a standard 400 V socket (3P+N+E).
Rent or buy?
Both: short-term rental installed by VISU, long-term rental with team training, or purchase. See our offers.
