  • Description

CA3KN31ED is Schneider Electric's TeSys K control relay in a 3NO+1NC arrangement, built around a 48 V DC coil with electronic surge suppression and rated 10 A Ith at up to 690 V. It is rated for AC-15/DC-13 duty, used to control and duplicate pilot signals in motor control and interlocking circuits, and connects via screw clamp terminals on DIN rail or a mounting plate.

Selection Notes

Choose the 3NO+1NC version when the application needs three make contacts for parallel command signals alongside one break contact for interlocking or indication. The 48 V DC coil variant fits control circuits already wired at that voltage, so the contactor coil can be driven directly without an additional transformer tap. The DC coil has no inrush surge and a longer 30–40 ms closing time than the AC-coil CA2Kseries, which electronic surge suppression trades for lower steady-state power draw — relevant when the relay is driven from a PLC transistor output or a current-limited 24 V DC rail.
