The Furnas Brand Class 47 47AB10 series alternator relay
provides a means of automatically alternating
the operation of two separately mounted motor
driven pumps or compressors. This alternating
action assures even readiness and wear on both
pumps.
The Class 47 47AB10 series alternator is of industrial design
specifically for use in pump and compressor
applications. It is easily field installed and wired
in control panels, pump panels or as a
separately enclosed unit for surface mounting.
The alternator has single pole double throw
heavy duty 10 ampere silver cadmium oxide
contacts enclosed in a transparent dust cover.
The snap action contacts transfer when the unit
is de-energized. The circuit is never closed or
opened while current is being conducted. This
provides increased control life. The alternator is
wired to operate the second motor starter the
next time a pump operation is required.
