Schneider Electric CA2KN40M7 Control Relay

Schneider Electric's TeSys K CA2KN40M7 is a four-pole control relay with four normally open contacts, rated for control circuits up to 690 V and a 10 A load current on the NO contacts. This model is the 220–230 V AC coil variant within the CA2KN40 family, and is offered with flexible terminal options, including screw-clamp or spring-terminal connections, to suit different panel-wiring preferences. The coil can be configured with a built-in bidirectional peak-limiting diode suppressor or selected without an integral suppression device, depending on the application’s surge protection needs. As part of the TeSys K lineup, CA2KN40M7 benefits from Schneider Electric’s accessory ecosystem, enabling compatible add-ons and alternative mounting or wiring configurations to optimize cabinet space and wiring density. This relay is well-suited for energizing control circuits in industrial automation, such as machine controls, conveyors, fans, or other panel-mounted control logic, where compact size, reliable 10 A NO switching, and straightforward wiring support robust, predictable operation.
