Relationship of Mounting Distance between
K8AK-AW Relays and Input Current
(Reference Values)
The following diagram shows the relationship between the mounting
distances and the input current.
If the relay is used with an input current that exceeds these values,
the temperature of the K8AK may rise and shorten the life of the
internal components.
