● Maximum overload: 1000 A RMS. The accuracy is specifi ed on the
symmetrical waveforms.
● N1: The maximum verifi cation of current and frequency product is less than
400,000 A x Hz.
WARNING:
The measuring duty cycle should not exceed the following limits.
0 ~ 600 A RMS Continuous
600 ~ 700 A RMS 10 minutes ON, 10 minutes OFF
700 ~ 1000 A RMS 5 minutes ON, 20 minutes OFF.
