CTloggers™ use a current transformer that clips over the monitored wire to record the time-of-use by detecting the current draw. Applications include; hot water heaters, air conditioners, heat pumps, fans, commercial motors, pumps, computers, and virtually any electrical device.

CTlogger™ comes with a 150 Amp CT and has a built-in sensitivity adjustment giving you the option to monitor only the high power draw components of the metered device.

Optional large window CTs are available for monitoring bigger conductors.  The small opening measures 0.4" or 10mm, while the larger opening measures 2" or 51mm.
