Schneider Electric LA1KN22 TeSys K 2NO+2NC Top Mount Contactor Auxiliary Contact Block

The Schneider Electric LA1KN22 is a TeSys K series top-mount contactor auxiliary contact block providing a 2NO+2NC contact configuration for industrial control and automation applications. Designed to expand the signalling and interlocking capability of TeSys K contactors, the LA1KN22 mounts directly on top of the contactor body, minimising panel space and simplifying wiring. Weighing just 45 g, this compact block is ideal for space-constrained control panels.

Applications & Use Cases

• Motor Control Circuits: Extends auxiliary signalling on TeSys K contactors for motor start/stop feedback and interlocking.
• Industrial Automation: Provides additional control contacts for PLC input signals and status monitoring in automated production lines.
• Control Panel Wiring: Top-mount design saves panel space while delivering two normally open and two normally closed auxiliary contacts.
• Interlocking Schemes: Used in reversing starter and star-delta starter circuits where multiple auxiliary contacts are required.
