Schneider Electric CA3KN22FD Industrial Control Relay

Schneider Electric CA3KN22FD is a TeSys K control relay configured as a four-pole device with 2 normally open and 2 normally closed contacts, enabling compact, multi-path control logic in automation panels. It employs a 110 V DC standard coil and supports a maximum switching voltage up to 690 V, making it suitable for interfacing lower‑voltage control circuits with higher‑voltage loads. As part of the TeSys K family, this 4P (2NO+2NC) relay is designed to directly interface with PLCs and other control circuitry in industrial applications, delivering reliable switching for logic and interlocking tasks.
