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 specific application. The use of any coil voltage less than the rated coil voltage may compromise
the operation of the relay.
