B.7 Zero Phase Reactor (RF220X00A)
Note: 600V Insulated Unshielded Cable.
Diagram A
Please wind each wire 4 times around the core. The reactor must be put at inverter side as
close as possible.
Diagram B
Please put all wires through 4 cores in series without winding.
Note1: The table above gives approximate wire size for the zero phase reactors but the
Note2: Only the phase conductors should pass through, not the earth core or screen.
Note3: When long motor output cables are used an output zero phase reactor may be
Single-core
Three-core
Cable type
(Note)
UNIT: mm(inch)
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.
