●Relationship of Mounting Distance between K8AK-AS 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.
