Schneider Electric LRD04. Overload Relay Module

Schneider Electric LRD04 is a TeSys Deca thermal overload relay that provides motor overload protection in 690 VAC circuits. It covers a current range of 0.4 to 0.63 A and features 1 normally open plus 1 normally closed contact (1NO+1NC) for monitoring and interlocking in control circuits. The device uses screw clamp terminals for secure wiring and is rated Class 10A, ensuring reliable protection by opening the circuit when an overload condition occurs. Designed to be paired with TeSys Deca contactors to form a complete motor-protection assembly, the LRD04 is suitable for motors whose running current falls within the 0.4–0.63 A range at up to 690 VAC. As part of Schneider Electric's TeSys family, this overload relay integrates with the broader TeSys protection ecosystem to provide consistent performance in industrial motor starter configurations.
