Note 1: The table above gives
approximate wire size for the zero phase
reactors but the selection is ultimately
governed by the type and diameter of
cable fitted i.e. the cable must fit through
the center hole of zero phase reactors.
Note 2: Only the phase conductors should
pass through, not the earth core or screen.
Note 3: When long motor output cables
are used an output zero phase reactor
may be required to reduce radiated
emissions from the cable.
Diagram B
Please put all wires through 4 cores in
series without winding.
Diagram A
Please wind each wire 4 times around the
core. The reactor must be put at inverter
output as close as possible.
