Flexible Form Factor
The NXCT-F3 features a linear wrap-around sensing head that can be installed without breaking the current path. Current measurement does not depend on sensor position; all that is required is a whole number of turns around the conductor with the sensor loop end plugged back into its enclosure.

High Performance
The NXCT-F3 is a precision optical sensor available in a variety of measurement and protection accuracy classes over a wide temperature range.

Lightweight Fiber Optic Design
The all dielectric sensing head is easy to install and set up even on a temporary basis for calibration of another CT or optical sensor. A generous 20 meter sensor length allows the user to configure the sensor through conduit or other supports while maintaining strike distance and safety requirements mandated for the system voltage and application. Longer head lengths are available as an option.

Software Adjustable Scale Factor
The scale factor, or electronic turns ratio, can be adjusted in software allowing a single sensor to address a broad range of primary currents as it is deployed in the field or moved from job to job. Furthermore, the user can adjust the sensitivity of the sensor by selecting the number of fiber turns around the conductor – more turns for small currents, fewer turns for large primary currents.
