Schneider Electric SE CA3KN31GD Control Relay

The Schneider Electric TeSys K CA3KN31GD control relay delivers reliable switching of auxiliary control circuits in industrial automation, powered by a 125 VDC coil within a 4‑pole configuration for precise signal control. It carries a 10 A (thermal) current rating and provides 3 normally open plus 1 normally closed auxiliary contacts, making it suitable for PLC control panels, motor starter assemblies, conveyors, packaging equipment, HVAC controls, and other automated machinery where dependable control signaling is essential. The DC coil includes a built‑in bidirectional peak‑limiting diode suppressor, and the unit is panel or DIN‑rail mountable with screw clamp terminals for secure wiring. Designed for industrial environments, it supports a rated operating voltage up to 690 VAC while maintaining 125 VDC coil operation, and is part of the TeSys K family from Telemecanique (Schneider Electric) under model CA3KN31GD. Common replacements include Schneider Electric CA3KN31BD, Allen‑Bradley 700‑CF310EJ, and Siemens 3TH4231.
