Auxiliary Contact Block 2NO/2NC

The Schneider Electric LA1KN22 is an auxiliary contact block designed for industrial control circuits. It adds four switchable contacts to compatible TeSys K series contactors or relays. This component suits panel builders and maintenance engineers expanding control logic in automation panels.

Front-mount IP20 screw-clamp terminals

The block mounts on the front of the device for quick access during wiring or inspection. Screw-clamp terminals accept solid or stranded conductors without special tools. An IP20 rating protects fingers from live parts during routine checks.

Four contacts in one compact block

Two normally open and two normally closed contacts let you signal status, interlock circuits or drive indicator lights from a single mounting point. The 690 V AC rating covers common industrial control voltages. Compatibility with TeSys K frames X, Y and Z simplifies stocking for multi-size panels.
