Schneider Electric CA2KN31F7 Control Relay Contactor

Schneider Electric CA2KN31F7 TeSys K control relay/contactor is a four-pole device that integrates three normally open contacts and one normally closed contact (3NO + 1NC) in a compact form, energized by a 110 V AC coil to switch standard AC control circuits in industrial panels. With a maximum switching voltage of up to 690 VAC and a current rating of 10 A, the CA2KN31F7 is suited for controlling moderate-power line loads such as motors, pumps, or auxiliary circuits, while keeping wiring simple and compatible with Schneider Electric's TeSys K ecosystem. The unit is designed for DIN rail mounting in control cabinets, and its footprint is roughly 45 mm wide by 58 mm high, offering a compact solution that fits alongside other TeSys K components and enables consistent, scalable control architectures. By providing both NO and NC paths in a single module, the CA2KN31F7 reduces component count and simplifies control logic, making it a practical choice for engineers implementing Schneider Electric automation systems that require reliable 110 V AC control and robust AC switching.
