Schneider Electric CA2KN40F7 AC Magnetic Contactor

Schneider Electric CA2KN40F7 TeSys K control relay is a 4P4NO AC magnetic contactor with a 110 V AC coil, delivering four independent normally open paths that are switched on energization. It is designed to operate with a maximum switching voltage of up to 690 VAC, making it suitable for coordinating auxiliary circuits in control panels and automation systems alongside larger contactors. As part of the TeSys K family, the CA2KN40F7 provides compact, reliable electromagnetic control for applications requiring multiple controlled outputs from a single coil signal—ideal for sequencing, interlocking, conveyors, pumps, fans, and other industrial equipment where precise control of several circuits is needed from standard 110 V control logic.
