AEMC MD300 Data sheet

AC Current Probe Model MD301
The Model MD301 is built for ruggedness, versatility and ease of use. It is designed with a unique hook-shaped jaw that enables the user to “pry” into or “hook” onto cables (will accept 2 x 500kcmil) or even smaller bus bars.
The Model MD301 measures up to 500A. It provides a voltage output proportional to the measured current.

This voltage output enables instruments without current ranges to measure, display or log currents on an AC voltage range.
The electronics and batteries are self-contained in the handles. The output of AC probes is
d c /Aa c .
1mV
