Schneider Electric LA1KN20 Contact Block

The Schneider Electric LA1KN20 is a front-mount auxiliary contact block designed for industrial control circuits. It provides two normally open contacts rated at 10 A for switching AC loads up to 690 V. The transparent housing allows visual inspection of contact status. It integrates with TeSys and TeSys K series contactors for automation panels.

Compatibility check before ordering

Verify that your existing contactor belongs to the TeSys or TeSys K series and matches the specified frame sizes X, Y or Z. Ensure the control circuit voltage does not exceed 690 V AC and the load current stays within the 10 A rating. Confirm that front mounting is suitable for your enclosure layout and that screw clamp terminals match your wiring method.

Thermals noise and power draw

The IP20 enclosure protects against solid objects but offers no water ingress protection, so install it inside a suitable cabinet. Contact resistance generates minimal heat during normal 10 A operation, and the device produces no audible noise as it has no moving parts or coil. Power consumption is limited to the control circuit driving the host contactor.

Questions about this item

What comes with the LA1KN20 contact block and is anything else required for installation?

The contact block is supplied as a single unit with screw clamp terminals for wiring. Mounting hardware and control circuit wiring are not included and must be sourced separately.

Which version of the LA1KN20 should I choose for a 10 A, 690 V AC control circuit?

This model provides two normally open contacts rated at 10 A and 690 V AC, matching that requirement directly.

How does the 10 A rating apply when the block is fitted to a TeSys K contactor?

The 10 A AC rating is the maximum current each of the two normally open contacts can switch when mounted on a compatible TeSys K frame.
