How Many Auxiliary Contacts Can be Added to the LK4QU3N Disconnect?

Issue:
Needs to know the maximum number of contacts they can add.

Product line:
IEC Style Disconnect Switches

Environment:
LK4 Disconnect Switches

Resolution:
We have two aux switch options, LK4AD10N which is 1 contact and LK4AD20N which is 2 contacts.  The contacts are field installable as NO or NC, but you can only mount one block onto the LK4QU3N disconnect.

If additional contacts are needed, consider an interposing relay.
