NI 333 Leakage current clamp626005024
Earth leakage current clampAt first glance, the NI 333 looks like a normal current clamp, but due to a special construction of the clamp, very small currents and differential currents can be measured. The NI 333 is equipped with an ergonomic housing with a wide mouth (opening).
This allows conductors to be measured from even
The mouth of the current clamp is very sensitive, also well insulated. This not only measures the basic frequency of 50 / 60Hz, but also higher frequencies. To suppress the effect of high-frequency noise, a low-pass filter has been developed to filter out the higher frequencies. This makes the range from 40 Hz to 1 kHz. The measured values are accurately displayed on the clear LCD display.
