INFRATEK Switzerland 0-3000A Flexible Current Clamp



0-3000A Flexible Current Clamp

 Back

The RR3030 is an AC current probe utilising the Rogowski principle.
It can be used to measure currents up to 3000A when used in conjunction
with Infratek Power Analyzers. The flexible and lightweight measuring head
allows quick and easy installation in hard to reach areas.
