Target Applications & Sectors

Main LV switchboards & motor control centresCommercial building tenant energy sub-meteringStandby generator control & transfer panelsIndustrial plant automation & SCADA systemsSolar PV generation monitoring & net meteringPumping station level & dry-run control

Using the free Lovato NFC smartphone app, you can configure parameters, set CT ratios, and clone settings simply by holding your smartphone next to the unpowered device faceplate, saving hours of commissioning time.

Split-core CTs open up and clamp directly around existing cables or busbars without disconnecting the power or unbolting cables, making them ideal for retrofit sub-metering installations.
