single-phase appliCaTions
Some three-phase line reactors are listed for use with single-phase input power. Follow the
connection diagram shown below. Make sure that terminals B1 and B2, if present, are properly
insulated before any connections are made. If a 3-phase reactor is used on the line side of a
single-phase input drive application, ensure that the actual single-phase current does not exceed
the Line Reactor's current rating (example: a 3-phase, 5hp Line Reactor and 3-phase 5hp drive will
not handle enough current to power a 5hp motor on a single-phase supply - both the drive and the
Line Reactor will have to be upsized).
