Schneider LA1KN22 Auxiliary contact block

The Schneider Electric LA1KN22 is an auxiliary contact block from the TeSys K range, featuring 2 normally open (NO) and 2 normally closed (NC) instantaneous contacts. It mounts on the front of TeSys K LC1K contactors and CA2K/CA3K control relays, extending their contact capacity for signalling and interlocking circuits. Rated at 690 V AC with a conventional free air thermal current of 10 A at 50°C, it suits a wide range of industrial control applications.
