Technical Assistance [phone] www.aemc.com1of 4

The Model MN307 is the latest in
compact AC current probes. It is
designed to meet the most stringent
demands in industry and electrical
contracting. Model MN307 meets
EN 61010, 600V, Cat. III safety
standards and is CE Marked and
UL approved for Canada and United
States.

The Model MN307 has a 0.78" (20mm)
jaw opening and accommodate
conductors up to 250MCM. The
unique hooked jaw design facilitates
clamping and hooking onto
conductors. Polycarbonate materials
and ultrasonic welding are used
throughout to ensure ruggedness
and overall lasting reliability.

The Model MN307 is a high perform­ance model and uses a custom nickel
core to improve accuracy and phase
shift on the low end of the measure­ment range. The Model MN307 is an
excellent probe to be used in power
and low level current measurement
applications.
