Schneider Electric Telemecanique CA2-DN40 Control Relay

The Schneider Electric Telemecanique CA2-DN40 Control Relay delivers reliable auxiliary switching in industrial control circuits, featuring a 24 V AC, 50/60 Hz coil and four normally open contacts for coordinating control signals in panels and machinery. As part of the CA2 Series, it provides 4 poles with a conventional thermal current (Ith) of 10 A, rated operational voltage up to 660 V AC, maximum switching voltage of 600 V AC, and an AC-11 current rating of 6 A at 500 V. The device uses screw clamp terminals and supports mounting on 35 mm DIN rails or panel surfaces, with IEC 60947-compliant design. Common applications include motor control centers, control panels, packaging machinery, conveyors, and process equipment where reliable auxiliary contact switching and PLC interfacing are required; common replacements include Schneider Electric CA2KN40B7 TeSys K, CAD40B7 TeSys D, and CAD50B7 TeSys D control relays.
