Description
Fluke i400s AC Current Clamp (400A)
The Fluke i400s AC Current Clamp (400A) is built for use with Fluke scope and power quality meters to enable current measurements up to 400A AC. Many power quality testers support up to four of these clamps, allowing full measurements of electrical systems.
CAT IV 600V and CAT III 1000V safety rated, the i400s can be used to test safely at all times and clamps securely around a conductor without the need to break the circuit and carry out invasive testing. It can used on conductors with a maximum diameter of 32mm and it is possible to use this device with multimeters as well (requires the use of a PM9081/001 BNC/Banana Adapter – sold separately).
Two ranges are available on the device: 40A and 400A with 1mV/Amp output.
