Schneider Electric LRD05 Electromechanical Relay

LRD05 is Schneider Electric’s TeSys Deca thermal overload relay, a compact electromechanical device that protects AC motors and circuits from overloads when paired with TeSys Deca contactors. It is rated for up to 690 VAC and provides a current-setting range of 0.63–1 A (with additional selectable ranges listed by Schneider Electric), plus 1 normally open and 1 normally closed contact (1NO+1NC) for control circuitry. The relay features screw-clamp terminals for secure wiring and is classified for Class 10A thermal protection. Used as part of the TeSys Deca motor-protection family, the LRD05 interrupts motor current to prevent overheating, making it suitable for small-to-medium industrial motors in 690 VAC networks. Its straightforward installation and reliable overload protection make it a practical choice for motor control panels that require robust thermal protection and simple wiring.
