Schneider Electric LRD350 Industrial Low-Voltage Relay

The Schneider Electric TeSys Deca LRD350 differential thermal overload relay provides motor protection when used with TeSys LR.D contactors, forming a complete TeSys LR.D starter assembly for industrial motor control in panels and switchgear. It’s rated for 37 to 50 A and supports operation up to 690 V, with a selectable trip configuration of 1 normally open and 1 normally closed contact (1NO+1NC), a class 10A thermal-trip rating, and EverLink connection technology that supports quick, reliable terminations. The device uses screw-clamp terminals for both outgoing cables and the control circuit, and it’s available in black-model variants within the LR.D family to suit panel aesthetics or existing equipment color schemes. When paired with a compatible LR.D contactor, the LRD350 provides coordinated overcurrent protection and a concise, maintenance-friendly wiring solution for motor control applications.
