Values can change due to the switching frequency, desired reliability levels, environmental conditions and in-rush load levels. It is recommended to test actual load conditions for the
application. It is the user’s responsibility to determine the performance suitability for their speci
fi
c application. The use of any coil voltage less than the rated coil voltage may compromise
the operation of the relay.
