Industrial Auxiliary Contact Block
The Schneider Electric LA1KN11 auxiliary contact block adds one normally open and one normally closed contact to compatible motor starters. It mounts on the front of TeSys K frame sizes X, Y and Z. Rated for 10 A at 690 V AC, it uses screw clamp terminals for secure wiring. The transparent housing provides an IP20 protection rating.
Front-Mount Contact Expansion
This block replaces the need for a separate control relay when only one additional NO and NC contact is required. It fits directly onto the starter face without extra panel space or DIN rail hardware. The upgrade is worth it when the application demands a simple, compact contact addition with a 690 V AC rating. Installation uses the existing starter mounting points.
Panel Builders Adding One NO/NC Pair
Electricians and panel builders who need a single extra contact pair on a TeSys K starter will find this block a direct fit. It suits control circuits staying within the 10 A and 690 V AC limits. Buyers who need more than two contacts, a different mounting style or a higher current rating should look at other auxiliary block configurations.

Questions about this item
Does the LA1KN11 use screw-clamp terminals for wiring?
Yes, the block has screw-clamp terminals that accept standard ferrules or stripped wire for secure connections.
What is the correct orientation when snapping the block onto the front of a TeSys K contactor?
Align the moulded guide ribs with the contactor's front slots and press firmly until the latch clicks; the transparent housing lets you verify full engagement.
When should the auxiliary contact block be inspected or replaced?
Check contact resistance and terminal tightness during scheduled panel maintenance; replace the block if the IP20 housing shows cracking or the contacts exceed 10 A rated current.
