AcuAmp CTF series split core current transformers provide an easy-to-install, compact and cost-effective means of measuring AC current, producing a 0-5 A output proportional to the current flowing through the sensing window. AcuAmp AC transformers feature a larger than average sensing window and a split-core case for convenient installation over large wires or bus bars without disconnecting. The compact design saves space in control panels by remotely locating the sensing of the current closer to the load. Primary current ratings are from 150A to 1000A. The 5A output of these current transformers is compatible with most standard power monitors and panel meters, ammeters, wattmeters, instrumentation and energy management systems. Starting at $64.50, AcuAmp AC current transformers have a 5-year warranty and are cURus, CE approved.
