Schneider Electric Telemecanique CA2-DN31U6 Control Relay

The Schneider Electric Telemecanique CA2DN31U6 Control Relay is a four-pole auxiliary switching device for industrial control panels, driven by a 240 V AC, 60 Hz coil (U6) and delivering 3 normally open plus 1 normally closed contact configuration. It handles up to 10 A conventional current (Ith) with a maximum switching voltage of 600 V AC and is rated for Ue up to 500 V AC and Ui up to 660 V, with screw clamp terminals for secure wiring and mounting on a DIN rail or panel. Designed for auxiliary control, PLC interfacing, machine sequencing, interlocking, and signaling in motor control centers, packaging machinery, conveyors, and process equipment, this relay is built for industrial automation environments that demand reliable auxiliary contact switching. It conforms to IEC 60947 / EN 60947 and also lists UL, CSA, and VDE 0660 standards, supporting widespread compatibility. Common replacements include the TeSys K and TeSys D lines, such as CA2KN31U7, CAD31P7, and CAD32P7, providing equivalent or compatible switching options.
