The Class 47 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 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.
