Reliability tests

The test results in table 6.4 were gathered from a 1 sec ON/OFF test cycle. Please note that
the over current induced by in-rush greatly reduces the relay contacts service life. The rated life
for an inductive AC load such as a contactor or solenoid valve is 500,000 operations at 20VA.
