The NIST TRIO Motorscope is the three-phase version of the UNO. It learns how much power your pump normally draws and switches it off when something is wrong. Wire it into your existing starter or control box; if you need a complete starter as well, choose the TRIO Panel.
What it protects against
- Dry-run (under-load) protection with an adjustable recovery timer, 4 minutes to 16 hours
- Overload (jammed pump), over- and under-voltage
- Phase failure, phase sequence change and phase imbalance
- WiFi and Bluetooth: monitor and switch the pump from your phone with the free NCS Toolbox app
- Remembers the last 100 trips with date and time
- 8 weekly timers and a start-up sequencer
Note: it does not protect against lightning; fit surge protection as well.
- Motor: 400V three phase, up to 5.6kW
