IC-640: Three-phase unbalanced wattmeter clamp 600 V, 600 A

IC-640: Three-phase unbalanced wattmeter clamp 600 V, 600 A

Compact CATIII and CAT V wattmeter clamp with transient protection designed to work in any location, even in confined spaces. It can measure impedance, grid frequency (power frequency), continuity and record the system energy consumption.


The IC-640 professional, compact wattmeter clamp can measure unbalanced three-phase loads and store in its internal memory the consumption in kW/h. The IC-640 clamp can take TRMS measurements in alternate current (AC) up to 600 A, analyze the three-phase and single-phase power, measure the total power factor and the impedance.

Its big LCD screen is easy and convenient to read and the instrument design, with a high level of functionality, allows a single hand easy operation.

The functions in the IC-640 wattmeter clamp make it a perfect tool for advanced applications in the field of the electrical power distribution.
