Schneider Electric LRD16 Overload Relay

Schneider Electric's TeSys LRD16 thermal overload relay protects 3‑phase motors in TeSys LRD/Deca starter configurations, offering reliable motor protection with a nominal current rating of 9–13 A and a class 10A thermal protection class. It is designed to be paired with a TeSys D/Deca contactor to form a compact, integrated motor starter that interrupts power when an overload occurs, helping prevent motor damage and nuisance trips. The LRD16 variant can include a supplementary auxiliary contact (1NO+1NC) for status signaling to the control circuit, enabling simple feedback to PLCs or motor control logic. Wiring is straightforward thanks to screw‑clamp terminals that provide secure, vibration‑resistant connections in demanding industrial environments. This relay is suitable for typical motor protection needs in automation panels, pumps, fans, conveyors, and other driven equipment, where dependable overload sensing and fast, clear signaling improve overall system reliability. For designers needing precise trip coordination, the LRD family offers clearly defined current ranges within the 9–13 A envelope, and the LRD16 is specifically tuned for applications at the 9–13 A load level, ensuring a balance between protection and motor efficiency.
