Big 3 phase line filters.
Where I work, we have switching power supplies that use Shaffner's big 45
amp, three phase, dual stage, 480V line filters. The design has the
terminals arranged such that they tend to get easily damaged connectors.
Although the damage does not affect the filter, it often requires that the
thing be replaced if the supply comes back for repair (like the wire is
nicked). As a result, I see a fair number being tossed in the trash that
really can be very easily fixed and used.
If anyone has a use for these and doesn't mind paying for about ten bucks
shipping I will keep an eye out for you and snag them from the melting
pot... It is a shame to see them go to waste...
